Installing or Replacing Components

This chapter describes the replacement and other maintenance procedures for the Cisco Nexus 7000 Series switch components. You can also use these procedures for installing modules and other features purchased after you receive the switch.

A Cisco Nexus 7000 Series switch is designed for redundancy, which means that you can replace its modules, fan trays, and power supply units if there is at least one other of the same type operating during the replacement process.

This chapter includes the following sections:

Replacing an AC Power Supply Unit During Operations

The Cisco Nexus 7000 Series switches use a load-balanced power supply that uses up to four AC or DC power supply units. The AC power supply units convert up to 1.2 kW, 1.4 kW, 3 kW, 3.5 kW, 6 kW, or 7.5 kW of AC power to DC power for system operations. If you can set one power supply unit in standby mode and have the required power load balanced by the remaining online power supply units, you can replace the standby power supply unit with another power supply unit without interrupting system operations.


Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029



Note If a replacement power supply unit is not available and you do not have a blank plate to cover the empty power supply bay, you should leave the original power supply in the bay until you have the replacement unit.


This section describes how to replace an AC power supply unit and includes the following topics:

Required Tools

Before you replace an AC power supply unit, make sure that you have the following tools and equipment:

  • Number 1 Phillips screwdriver with torque capability
  • Shipping materials
  • Antistatic mat
  • Replacement AC power supply unit

Caution When you handle the Cisco Nexus 7000 Series components, you must follow ESD protocol at all times to prevent ESD damage. This protocol includes but is not limited to wearing an ESD wrist strap that you connect to the earth ground.

Installing a 6-kW or 7.5-kW AC Power Supply Unit During Operations

After you remove an AC power supply, you can replace it with another power supply or replace it with a blank plate until another power supply is available. If you need to install a DC power supply unit, see the “Installing a 6-kW DC Power Supply Unit During Operations” section.


Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034


To install an AC power supply unit while a Cisco Nexus 7000 Series switch is operating, follow these steps:


Step 1 Unpack the replacement power supply unit and place it on an antistatic mat. If you are unpacking a 6-kW power supply unit, you must also unpack one or two power cords. If you are unpacking a 7.5-kW power supply unit, two power cords are already attached to the power supply unit.

Step 2 Ensure that the power switch on the power supply unit is in the standby (STBY) position and that the AC power cords are not plugged into the AC power supply.

Step 3 Holding the AC power supply unit with one hand on its handle and the other hand under the bottom (longest side), align the back of the power supply unit with the power supply bay and slide the power supply into the power supply bay. Make sure the power supply unit is fully seated in the power supply bay and that its four captive screws are aligned with their holes in the chassis.


Note The 6-kW AC power supply unit weighs 22 pounds (10 kg), and the 7.5-kW AC power supply unit weighs 26.4 pounds (12 kg). Use two hands to safely hold and move a power supply unit.


If you cannot push the power supply unit all the way into its bay, make sure that the power switch is turned to STBY before pushing the power supply unit all of the way into the bay.

Step 4 Screw in the four captive screws and tighten to 8 in-lb (0.9 N·m).

Step 5 Plug the power cables into the power jacks on the front of the power supply unit.

  • For 6-kW of power, plug two power cables into the two power jacks.
  • For 3-kW of power, plug one power cable into one of the two power jacks.

Note The 6-kW AC power supply unit does not ship with power cables attached to it, so you must attach one or two of those cables. If necessary, you can remove the cables from the AC power supply unit that you removed. The 7.5-kW AC power supply ships with permanently attached power cables, so you do not need to attach power cables to that power supply unit.


Step 6 Plug the power cables that are already attached to the power supply unit into the AC power source.


Tip For power redundancy, plug each power cable into a separate AC power supply circuit.


Step 7 Turn the Power switch from STBY to ON.

Step 8 Verify the power supply operation by checking that the power supply LEDs are in the following states:

  • Input 1 LED is green.
  • If a second AC power cord was connected, the Input 2 LED is green.
  • Output LED is green.
  • Fault LED is not on or flashing.

If one or more of these LEDs is red, turn the power switch to standby (STBY), check the AC power connections for the line in standby (STBY), and then turn the power switch back to ON. The Input and Output LEDs for the connected power supply units should be green.

For more information on the power supply unit LED states, see Appendix D, “Chassis and Module LEDs.”


 

Replacing a DC Power Supply Unit During Operations

The Cisco Nexus 7000 Series switches use a load-balanced power supply that uses up to three or four AC or DC power supply units. If you can set one power supply unit in standby mode and have the required power load balanced by the remaining online power supply units, then you can replace the standby power supply unit with another power supply unit without interrupting system operations.


Note If a replacement power supply unit is not available and you do not have a blank plate to cover the empty power supply bay, you should leave the original power supply in the bay until you have the replacement unit.



Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

For more information on the power supply unit LED states, see Appendix D, “Chassis and Module LEDs.”


 

Replacing a Supervisor Module

The Cisco Nexus 7000 Series switches can be configured with one or two supervisor modules. If the system has two supervisor modules, you can replace one of the supervisors while the other one manages system operations. If the system has only one supervisor, you must bring the system down to replace the supervisor module because the supervisor module is required for managing operations.


Note If you need to bring down the switch to change supervisors, you must also copy the running configuration, system messages, VDC configurations, and licenses onto a USB drive before removing the supervisor module as explained in the “Replacing a Supervisor Module” section.



Caution Make sure that you do not accidentally press one or more of the ejector release buttons on the I/O, supervisor, and fabric modules. These buttons and their mechanical levers are designed so that you can easily power down and remove these modules when you need to replace them. If you press one of these buttons, the lever for that button releases from the front of the module, but the module remains operational and connected to the system. If you press the other ejector button on the same module at the same time as you press the first button or while the lever for the first button is released, the lever for the second button releases, and the module powers down and disconnects from the system.

To minimize the chance of accidentally disconnecting a module with a released lever, press the lever back toward the module until it clicks. If both levers are released, the system has disconnected and powered down the module, and the STATUS LED will be unlit. To reconnect and power up the module, either remove and reinsert the module in the chassis or use system commands to power it on.

This section describes how to replace supervisor modules and includes the following topics:

Required Tools

You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screws on the supervisor module.

Replacing a Redundant Supervisor Module During System Operations

During operations, one supervisor is active while the other (redundant) supervisor is in standby mode. You can replace either of these two supervisors. If you need to replace the active supervisor, it becomes the standby supervisor as soon as you press its ejector buttons.


Note A replacement supervisor module comes with one DIMM (4 GB of memory) or, if your switch is running Cisco NX-OS 5.1 (or later release), two DIMMs (8 GB of memory). If the switch not running a version of Cisco NX-OS that is compatible with using 8 GB of memory, then you must use only one DIMM (do not install an additional DIMM).



Caution If you cannot immediately replace a supervisor, either leave the supervisor in its slot until it can be replaced or replace it with a blank module so the system airflow is not disrupted. If the system airflow is disrupted for more than a couple of minutes, the system could overheat and shut down.


Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution Handle each supervisor or I/O module carefully using an ESD wrist strap, holding the module only on its carrier edges without touching any electronic circuitry, and placing the module on antistatic mats or repacking it in its original packing materials when it is not installed in the Cisco Nexus 7000 Series chassis.

To replace a supervisor module, follow these steps:


Step 1 Place an antistatic mat or antistatic foam where you can place the new and old supervisor modules.

Step 2 If the replacement supervisor is in a shipping box, prepare the module for installation by following these steps:

a. Open the shipping box for the module and remove the module from its antistatic wrapping.

b. If the plastic protector shown in Figure 10-4 is included with the module, remove it by pulling it past the back of the module. Keep the plastic protector and the other packing materials so that you can easily ship the module at a later time.

Figure 10-4 Removing the Plastic Protector from the Supervisor Module

 


Caution To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming in contact with the circuitry.

Step 3 On the currently installed supervisor module (the module that you are going to remove), loosen the two captive screws identified in View A of Figure 10-5.

Figure 10-5 Unseating a Supervisor Module

 

1

Unscrew two captive screws.

3

Simultaneously swing open both ejector levers to unseat the module.

2

Simultaneously press both ejector buttons.

Step 4 Press the ejector release buttons on the ends of the module (see View B of Figure 10-5) to push out the ejector levers and to disconnect the module.

If the chassis has two supervisor modules and you disconnect the active supervisor module, that supervisor goes into standby mode and the other supervisor automatically becomes the active supervisor.

Step 5 Disconnect the cables attached to the front of the module to be removed. Make sure that each cable is labelled for its port on the module.

Step 6 Simultaneously rotate the two ejector levers outward to unseat the module from the midplane connector (see View C of Figure 10-5).

Step 7 With a hand on each ejector, pull the module part way out of its slot in the chassis.

Step 8 Grasp the front edge of the module with your left hand and place your right hand under the lower side of the module to support its weight. Pull the module out of its slot.


Caution To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming in contact with the circuitry.

Step 9 If you are removing the module from a Cisco Nexus 7010 chassis, rotate the module 90 degrees counterclockwise so that it is horizontal and you can see its circuitry from above.

Step 10 Place the removed module in an antistatic bag.

Step 11 Repack the bagged I/O module in its original packing materials as shown in Figure 10-6.

Figure 10-6 Repacking a Supervisor Module

 

1

Put the module in an ESD bag.

7

Tape the flap to the box.

2

Place the bagged module on the foam pad.

8

Insert the two box sides into foam blocks.

3

Attach a side pad to each of the long sides of the module.

9

Place the box and its foam blocks into the larger box.

4

Fold the side flaps up along the side pads.

10

Fold the narrow flaps over the smaller box and foam blocks.

5

Fold the long flaps up along the ends of the module and then over the top of the module. Insert the two tabs on each flap into the side flaps.

11

Fold the wide flaps over the box.

6

Insert the folded box into the slightly larger box.

12

Tape the wide flaps together and to the box.

Step 12 On the replacement module, rotate both of the ejector levers away from the front of the module.

Step 13 If you are inserting the module into a Cisco Nexus 7010 chassis, rotate the module 90 degrees clockwise.

Step 14 Align the module to the chassis guides for the vacated slot (slot 5 or 6 on the Cisco Nexus 7010 chassis or slot 9 or 10 on the Cisco Nexus 7018 chassis), and slide the module part way into the slot.

Step 15 With one or both hands on the front of the module, push the module all the way into the slot until it seats on the midplane connector.

Step 16 Simultaneously push both ejector levers inward until they come in contact with the face of the module.

The module should be fully seated in the slot and the captive screws should be aligned with their holes in the chassis. The EMI gasket should close the gap between the new module and the module in the next slot to the right.

Step 17 Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9 N·m).

Step 18 Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the “Connecting to the Console” section.

Step 19 If the previous supervisor module was connected to an asynchronous device through a modem, connect the modem cable to the COM1/AUX SERIAL PORT as explained in the “Connecting to the Console” section.

Step 20 Reconnect the network management cable to the MGMT ETH port as explained in “Setting Up the Management Interface” section.

Step 21 Reconnect the CMP cable to the CMP MGMT ETH port as explained in “Connecting the Supervisor CMP Port” section.

Step 22 Verify that both supervisors have the same amount of memory by following these steps:

a. Use the show system resources command to see how much memory is installed in the active supervisor.

b. Use the system switchover command to make the other supervisor module active.

c. Use the show system resources command to see how much memory is installed in the other supervisor.

If one of the supervisor modules has more memory than the other supervisor module, you must either remove 4 GB from the module with 8 GB (see the “Removing 4 GB of Memory from a Supervisor Module” section) or add 4 GB to the module with 4 GB (see the“Adding 4 GB of Memory to a Supervisor Module” section).


 

Replacing a Supervisor Module in a Single-Supervisor System

If you need to replace the supervisor in a single-supervisor Cisco Nexus 7000 Series system, you must shut down the system before replacing the supervisor.


Note A replacement supervisor module comes with one DIMM (4 GB of memory) or, if your switch is running Cisco NX-OS 5.1 (or later release), two DIMMs (8 GB of memory). If the switch not running a version of Cisco NX-OS that is compatible with using 8 GB of memory, you must use only one DIMM (do not install an additional DIMM).



Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution Handle the supervisor module carefully using an ESD wrist strap, holding the module only on its carrier edges without touching any electronic circuitry, and placing the module on antistatic mats or antistatic foam when it is not installed in the Cisco Nexus 7000 Series chassis.

To replace a supervisor module in a single-supervisor system, follow these steps:


Step 1 Place an antistatic mat or antistatic foam where you can place the new and old supervisor modules.

Step 2 If the replacement supervisor is in a shipping box, prepare the module for installation by following these steps:

a. Open the shipping box for the module and remove the module from its antistatic wrapping.

b. If the plastic protector shown in Figure 10-7 is included with the module, remove it by pulling it past the back of the module. Keep the plastic protector and the other packing materials so that you can easily ship the module at a later time.

Figure 10-7 Removing the Plastic Protector from the Supervisor Module

 


Caution To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming in contact with the circuitry.

Step 3 Turn off the power on each of the power supply unit by turning its power switch to standby (STBY).

Step 4 Disconnect all of the cables attached to the front of the module to be removed.

Step 5 Loosen the two captive screws identified in View A of Figure 10-5.

Step 6 Press the ejector release buttons on the top and bottom ends of the module (see View B of Figure 10-5) to push out the ejector levers and to disconnect the module.

Step 7 Simultaneously rotate the two ejector levers outward to unseat the module from the midplane connector (see View C of Figure 10-5).

Step 8 With a hand on each ejector, pull the module part way out of its slot in the chassis.

Step 9 Grasp the front edge of the module with your left hand and place your right hand under the lower side of the module to support its weight. Pull the module out of its slot.


Caution To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming in contact with the circuitry.

Step 10 If you are removing a module from a Cisco Nexus 7010 chassis, rotate the module 90 degrees counterclockwise so that it is horizontal and you can see its circuitry from above.

Step 11 Place the removed module on the antistatic mat or repack it in its original packing materials as shown in Figure 10-6.

Step 12 On the replacement supervisor module, rotate both of the ejector levers away from the front of the module.


Caution To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming in contact with the circuitry.

Step 13 If you are inserting the module into a Cisco Nexus 7010 chassis, rotate the module 90 degrees clockwise.

Step 14 Align the module to the chassis guides for the vacated slot (slot 5 or 6 on a Cisco Nexus 7010 chassis or slot 9 or 10 on a Cisco Nexus 7018 chassis), and slide the module part way into the slot.

Step 15 With one or both hands on the front of the module, push the module all the way into the slot until it seats on the midplane connector.

Step 16 Slide the module into the slot until it seats on the midplane.

Step 17 Simultaneously push both ejector levers inward until they come in contact with the face of the module.

The module should be fully seated in the slot and the captive screws should be aligned with their holes in the chassis. The EMI gasket should close the gap between the replacement module and the module in the next slot.

Step 18 Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9 N·m).

Step 19 Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the “Connecting to the Console” section.

Step 20 (For Supervisor 1 modules only) If the previous supervisor module was connected to an asynchronous device through a modem, connect the modem cable to the COM1/AUX SERIAL PORT as explained in the “Connecting to the Console” section.

Step 21 Reconnect the network management cable to the MGMT ETH port as explained in the “Setting Up the Management Interface” section.

Step 22 (For Supervisor 1 modules only) Reconnect the CMP cable to the CMP MGMT ETH port as explained in the “Connecting the Supervisor CMP Port” section.


 

Replacing Supervisor 1 Modules with Supervisor 2 or Supervisor 2E Modules

Before migrating from Supervisor 1 modules to Supervisor 2 or Supervisor 2E modules, note the following guidelines:

  • This migration process is disruptive for switches with one or two supervisor modules because the power must be turned off for the switch.
  • Backward migration procedure (migrating from Supervisor 2 or Supervisor 2E modules to Supervisor 1 modules) is not provided.
  • We recommend that you use Cisco NX-OS Release 5.2 (or later release) on the Supervisor 1 module while performing the migration.
  • You cannot mix Supervisor 2 and Supervisor 2E modules in a production environment (this mix of modules is supported only while you are migrating from using Supervisor 2 modules to Supervisor 2E modules as explained in the “Replacing Supervisor 2 Modules with Supervisor 2E Modules” section). You must replace redundant Supervisor 1 modules with either two Supervisor 2 modules or two Supervisor 2E modules.
  • If you plan to enable the admin VDC feature on the Supervisor 2 or Supervisor 2E modules, be sure to complete the entire migration procedure before enabling this feature (see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide ).

To migrate from using Supervisor 1 modules to Supervisor 2 or Supervisor 2E modules, follow these steps:


Step 1 Insert a USB drive in the top USB port (usb1) in the active supervisor 1 module. If the Supervisor 2 or Supervisor 2E module shipped with an extra USB drive, you can insert that USB drive in the usb1 drive on the Supervisor 1 module.


Note Do not use the USB drive that is in the LOG FLASH port.


Step 2 Format the drive by using the format command.

switch(config)# format usb1:

Step 3 Copy all of the VDC configurations for the switch to the USB drive by using the copy running-config command.

switch(config)# copy running-config usb1:configuration_file_name vdc-all

Step 4 Backup the installed licenses for the switch to the USB drive by using the copy licenses command.

switch(config)# copy licenses usb1:licenses_archive_file_name.tar

Note You must use the tar extension for the archive file. This file will contain all of the license files that were installed on the Supervisor 1 module.


Step 5 Determine the Cisco NX-OS software release to use on the Supervisor 2 or Supervisor 2E modules. We support Cisco NX-OS Release 6.1(1) (or later release) on those modules but another one might be recommended. Additionally, the most recommended maintenance release might not be the one that ships with the Supervisor 2 or Supervisor 2E modules. We recommend that you check with the following documents for the recommended software release:

  • Minimum Recommended Cisco NX-OS Releases for Cisco Nexus 7000 Series Switches
  • Cisco Nexus 7000 Series NX-OS Release Notes, Release 6.1

Step 6 Copy the Supervisor 2 or Supervisor 2E version of the kickstart, system, and EPLD (optional) images to the USB drive by using the copy command.

switch(config)# copy scp://path/n7000-s2-kickstart.6.1.1.bin usb1:
switch(config)# copy scp://path/n7000-s2-dk9.6.1.1.bin usb1:
switch(config)# copy scp://path/n7000-s2-epld.6.1.1.img usb1:

Note This example specifies the NX-OS Release 6.1(1) images. For a later release, use the later release number in the .bin or .img file name.



Caution Use -s2- images with Supervisor 2 or Supervisor 2E modules. If you use an -s1- image with a Supervisor 2 or Supervisor 2E module, the supervisor will not boot up.


Note Although the Supervisor 2 and Supervisor 2E ship with updated EPLD images, you might need to update the EPLD images on the other modules on the switch. For example, migrating from Supervisor 1 modules to Supervisor 2 or Supervisor 2E modules on switches that use Fabric 2 modules requires EPLD updates for the fabric modules. For more information, see the Cisco Nexus 7000 Series FPGA/EPLD Upgrade Release Notes, Release 6.1 or later release.


Step 7 Turn off the power to the switch by turning the power switch on each power supply from ON to STBY (Standby). The Output LED turns off on each power supply and the Status LEDs turn off on all of the supervisor and I/O modules.


Caution If any of the supervisor or I/O module Status LEDs is turned on (showing any color), stop at this step until you are able to turn off those modules.

Step 8 For each Supervisor 1 module installed in the switch, remove the module and replace it with a Supervisor 2 or Supervisor 2E module as explained one of the following sections:


Caution If the switch has two supervisor modules, be sure that both supervisors are the same type. Do not mix Supervisor 1 modules with Supervisor 2 or Supervisor 2E modules and do not mix Supervisor 2 modules with Supervisor 2E modules.

Step 9 Power up the switch by turning the power switch on each of its power supplies from STBY (standby) to ON. The Output LED on each power supply turns on and eventually turns green when the power supply is sending power to the switch. The Status LED on each installed supervisor module also turns on when the module begins to turn on. The supervisor that becomes active has a green ACTIVE LED (the standby supervisor module has an amber ACTIVE LED).

Step 10 Remove the USB drive from the Supervisor 1 module (this drive has copies of the Supervisor 1 configuration, license, and software images) and insert it in the Slot0: USB port on the active Supervisor 2 or Supervisor 2E module (ACTIVE LED is green).

Step 11 Connect a console to the active supervisor module as explained in “Connecting to the Console” section.

Step 12 If you are setting up the initial configuration for the supervisor module, the initial setup script will ask you if you want to enforce the secure password standard. Make your selection, enter your password, and then confirm the password by entering it again.

---- System Admin Account Setup ----
Do you want to enforce secure password standard (yes/no) [y]:
Enter the password for “admin”:
Enter the password for “admin”:

Step 13 When you are asked to enable admin VDCs, enter no .

Do you want to enable admin vdc (yes/no) [no]:no

Step 14 When you are asked to enter the basic configuration, enter no .

Step 15 When asked to log in, enter the login and password that you specified in step 12.

User Access Verification
switch login:
Password:

Step 16 Verify that the switch is running the required version of the NX-OS software by using the show version command.

switch(config)# show version

Note If the version of NX-OS is not the same as you intended to use, copy the previously saved images from the USB drive in SLOT 0 to bootflash: and perform an upgrade to the appropriate version. For more information, see the Cisco Nexus 7000 Series NX-OS Software Upgrade and Downgrade Guide.


Step 17 Copy the TAR archive containing the license files from the USB SLOT 0 drive to bootflash:, extract the archive, and install the licenses by using the copy , tar extract , and install license commands. Repeat the install license command for each extracted license file.

switch(config)# copy slot0:licenses_archive_file_name.tar bootflash:
switch(config)# tar extract bootflash:licenses_archive_file_name.tar to bootflash:
switch(config)# install license bootflash:license_file_name.lic

Note The tar extract command requires that the TAR file be located in bootflash: or volatile:.


Step 18 Make sure that all I/O modules are online and that the standby supervisor is in ha-standby mode by using the show module command.

switch(config)# show module
Mod Ports Module-Type Model Status
--- ----- ----------------------------------- ------------------ ---------------
2 0 Supervisor module-2 N7K-SUP2E active *
6 0 Supervisor module-2 N7K-SUP2E ha-standby
7 48 1/10 Gbps Ethernet Module N7K-F248XP-25 ok
...
 

Step 19 If there are Fabric 2 modules in the switch, upgrade the Fabric 2 EPLDs (see the “Configuring EPLDs” section).

Step 20 Restore the previously saved configurations by using the copy command to copy the configuration file in the USB drive to the running configuration.

switch(config)# copy slot0:configuration_file_name running-config

Note While the configuration is applied on the Supervisor 2 or Supervisor 2E module you will see an error that indicates a problem with the cmp-mgmt interface or AUX port. The Supervisor 2 and Supervisor 2E modules do not have the CMP utility nor the AUX port, so you can disregard this error message.

switch(config)# interface cmp-mgmt module 5
^
Invalid interface format at ‘^’ marker.
...
switch(config)# line com1
^
% Invalid command at ‘^’ marker.



Note If the imported configuration file includes configurations for Fabric Extenders (FEXs) and those modules are not up yet, you will see error messages for that. If that happens, we recommend that you run the FEX configuration again after the FEX modules come online. You can verify the status of the FEX modules and for the associated server-facing interfaces by using the show fex and show interface brief commands.



Note If you have not inserted the standby supervisor module until now, do not insert it during this step. Instead, wait until you complete this procedure before installing the standby supervisor module.


Step 21 Save the configuration in the startup configuration by using the copy running-config startup-config vdc-all command.

switch(config)# copy running-config startup-config vdc-all


 

Replacing Supervisor 2 Modules with Supervisor 2E Modules

Before migrating from Supervisor 2 modules to Supervisor 2E modules, note the following guidelines:

  • This migration process is not disruptive for switches with redundant (two) supervisors but it is disruptive for switches that have only one supervisor module.
  • Non disruptive backward migration (migrating from Supervisor 2E modules to Supervisor 2 modules during switch operations) is not supported—in a switch with two supervisor modules and an active Supervisor 2E module, a Supervisor 2 will not boot up nor synchronize with the active Supervisor 2E module.

To migrate from using Supervisor 1 modules to Supervisor 2 or Supervisor 2E modules, follow these steps:


Step 1 Replace one of the Supervisor 2 modules by following the steps in the “Replacing a Redundant Supervisor Module During System Operations” section.

Step 2 Verify that the Supervisor 2E module has 2 CPUs and 32 GB of DRAM by looking at the bootup output (see the highlighted portions in the following example).

CPU - 2 : Cores - 4 : HTEn - 1 : HT - 2 : Features - 0xbfebfbff
FSB Clk - 532 Mhz : Freq - 2144 Mhz - 2128 Mh
MicroCode Version : 0xffff0002
Memory - 32768 MB : Frequency - 1067 MHZ
 

Step 3 Monitor the console output for the active Supervisor 2. When the standby Supervisor 2E fully boots up, note that the console displays a SYSLOG message similar to the following:

2012 Jul 26 14:28:23 switch %SYSMGR-2-CTIVE_LOWER_MEM_THAN_STANDBY: Active Supervisor in slot 1 is running with less memory than standby supervisor in slot 2.

This message states that the Supervisor 2E module has more memory than the Supervisor 2 module (as expected).

Step 4 Verify that both supervisor modules have synchronized their states by using the show mod and show system redundancy ha status commands.

switch# show mod
Mod Ports Module-Type Model Status
--- ----- ----------------------- -------------- ---------
1 0 Supervisor module-2 N7K-SUP2 active
2 0 Supervisor module-2 N7K-SUP2E ha-standby
 
switch# show system redundancy ha status
VDC No This supervisor Other supervisor
------ --------------- ----------------
vdc 1 Active with HA standby HA standby
vdc 2 Active with HA standby HA standby
vdc 3 Active with HA standby HA standby
vdc 4 Active with HA standby HA standby
 

Step 5 Make the Supervisor 2E module active by using the system switchover command.

switch# system switchover

When the Supervisor 2E becomes active, the Supervisor 2 powers down and will not come up as a standby supervisor.

2012 Jul 26 14:50:19 switch %$ VDC-1 %$ %SYSMGR-2-SUP_POWERDOWN; Supervisor in slot 1 is running with less memory than active supervisor in slot 2
2012 Jul 26 14:50:19 switch %$ VDC-1 %$ %SYSMGR-2-CONVERT_STARTUP_ABORTED: Conversion of startup-config failed.
2012 Jul 26 14:50:19 switch %$ VDC-1 %$ %PLATFORM-2-MOD_PWRDN: Module 1 powered down
 

Step 6 Verify that the Supervisor 2E module is active and that the Supervisor 2 is powered down by using the show module command.

switch# show mod
Mod Ports Module-Type Model Status
--- ----- ----------------------- -------------- ---------
1 0 Supervisor module-2 N7K-SUP2 powered-dn
2 0 Supervisor module-2 N7K-SUP2E active *
...
 
Mod Power-Status Reason
--- ------------ ----------------------------
1 powered-dn Policy trigger initiated reset: Stdby has lower mem than active
 

Step 7 Remove the Supervisor 2 module, which is powered down (LEDs are off).

Step 8 Install a Supervisor 2E module in the open slot and connect it to the console (see the “Replacing a Redundant Supervisor Module During System Operations” section).

Step 9 Verify that both supervisor modules have synchronized their states by using the show mod and show system redundancy ha status commands.

switch# show mod
Mod Ports Module-Type Model Status
--- ----- ----------------------- -------------- ---------
1 0 Supervisor module-2 N7K-SUP2E active
2 0 Supervisor module-2 N7K-SUP2E ha-standby
 
switch# show system redundancy ha status
VDC No This supervisor Other supervisor
------ --------------- ----------------
vdc 1 Active with HA standby HA standby
vdc 2 Active with HA standby HA standby
vdc 3 Active with HA standby HA standby
vdc 4 Active with HA standby HA standby


 

Upgrading Memory for Supervisor 1 Modules

The Cisco Nexus 7000 Series Supervisor 1 modules use either 4 GB or 8 GB of memory. For switches that have two supervisor modules, each module must have the same amount of memory so that it can provide redundant services for the other. In order to use 8 GB of memory, a switch must be running Cisco NX-OS Release 5.1 or later release. If the switch is running an earlier release of Cisco NX-OS, the supervisor modules must have only 4 GB of memory installed.


Note The Cisco NX-OS software may require 8 GB of memory, depending on the software version you use and the software features that you enable. If your switch has Supervisor 1 modules with only 4 GB of memory, then you might need to upgrade the modules to 8 GB of memory by using the 8 GB supervisor upgrade kit (N7K-SUP1-8GBUPG=). This upgrade is not needed for switches that have at least 8 GB of memory (which includes Supervisor 1 modules with 8 GB and all Supervisor 2 and Supervisor 2E modules).


To determine the amount of memory installed in the active supervisor, use the show system resources command as shown in Example 10-1. To determine the amount of memory used by the standby supervisor module, use the system switchover command to make that module active and then use the show system resources command. This example shows the output for the show system resources command, which shows 4115768K (4 GB) of memory usage.

Example 10-1 Determining the Amount of Memory used by the active supervisor module.

switch# show system resources
Load average: 1 minute: 0.22 5 minutes: 0.25 15 minutes:0.15
Processes : 860 total, 3 running
CPU states : 0.0% user, 6.5% kernel, 93.5% idle
Memory usage: 4115768K total, 2747512K used, 1368256K free
 
switch#
 

The following guidelines can help you determine whether or not to upgrade an existing Supervisor 1 module:

  • When the switch memory usage exceeds 3 GB (75 percent of total memory), we recommend that you upgrade the memory to 8 GB.
  • If you create more than one VDC with XL mode enabled, or if you have more than two VDCs, 8 GB is required.

For additional guidance about whether or not to upgrade a supervisor module to 8 GB of memory, see Figure 10-8.

Figure 10-8 Supervisor Memory Upgrade Decision Flowchart

 

To determine which version of Cisco NX-OS that the switch is running, use the show version command.

This section includes the following topics:

Adding 4 GB of Memory to a Supervisor Module

If you need to add 4 GB of memory to the supervisor modules on your switch so that they have 8 GB of memory, the switch must be running NX-OS Release 5.1(1) or later release.


Note If the switch has two supervisor modules, both must have the same amount of memory. If you upgrade the standby supervisor module to 8 GB of memory, you must then switch the active supervisor to standby and upgrade the new standby supervisor to 8 GB of memory.



Note If you are using an earlier version of Cisco NX-OS, the supervisor modules can have only 4 GB of memory. If you need to remove 4 GB of memory to have only 4 GB of memory in a supervisor, see the “Removing 4 GB of Memory from a Supervisor Module” section.


To add 4 GB of memory to the supervisor modules, follow these steps:


Step 1 Follow ESD procedures, which include wearing an ESD wrist strap and placing antistatic foam or antistatic padding where you will place the supervisor module while working with it.

Step 2 Disconnect the cables attached to the front of the module to be removed. If there are two supervisors in the switch, disconnect the cables from the standby supervisor.


Note If the chassis has two supervisor modules and you disconnect the active supervisor module, that supervisor goes into standby mode and the other supervisor becomes the active supervisor.


Step 3 Loosen and fully unscrew both captive screws on the module.

Step 4 Press both ejector release buttons on the ends of the module (see Callout 2 in Figure 10-5) to push out the ejector levers and to disconnect the module.


Note If you stop this procedure at this point without removing the module and need to power it up, simultaneously press both ejector levers back to the face of the module until they click, secure both of the module captive screws to the chassis, and then use the no poweroff module slot_number command to power up the module.


Step 5 Simultaneously rotate the two ejector levers outward to unseat the module from the midplane connector (see Callout 3 in Figure 10-5).

Step 6 With a hand on each ejector lever, pull the module part way out of its slot in the chassis.

Step 7 Grasp the front edge of the module with one hand and place your other hand under the lower side of the module to support its weight. Pull the module out of its slot.


Caution To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming in contact with its circuitry.

Step 8 If you are removing the module from a Cisco 7010 chassis, rotate the module 90 degrees counterclockwise so that it is horizontal and you can see the circuitry from above.

Step 9 On the second memory slot from the front of the module, rotate both spring clips away from the slot (see Callout 1 in Figure 10-9).

Figure 10-9 Adding a 4-GB DIMM

 

1

On the second memory slot from the front of the supervisor module, rotate both spring clips out.

3

Add an 8 GB label to the right of the N7K-SUP-1 identifier on the front of the module.

2

Holding the DIMM by its edges, align it to the second memory slot and push it into place until the spring clips click into the DIMM.

Step 10 Holding the edges of the 4-GB memory board with one hand, slide it into the second memory slot from the front of the module until the two spring clips click into the DIMM (see Callout 2 in Figure 10-9).

Step 11 Place an 8-GB label on the front of the module and to the right of the N7K-SUP-1 identifier.

Step 12 Rotate both ejector levers away from the front of the supervisor module.

Step 13 Grasp the front of the supervisor module with one hand and place your other hand under the module to support its weight.

Step 14 Align the module to the open supervisor slot in the chassis and push the module into the slot until it makes contact with the midplane.

Step 15 Simultaneously push both ejector levers inward until they come in contact with the face of the module.

The module should be fully seated in the slot and the captive screws should be aligned with their holes in the chassis. The EMI gasket should close the gap between this module and the next module.

Step 16 Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9 N·m).

Step 17 Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the “Connecting to the Console” section.

Step 18 If the previous supervisor module was connected to an asynchronous device through a modem, connect the modem cable to the COM1/AUX SERIAL PORT as explained in the “Connecting to the Console” section.

Step 19 Reconnect the network management cable to the MGMT ETH port as explained in the “Setting Up the Management Interface” section.

Step 20 Reconnect the CMP cable to the CMP MGMT ETH port as explained in the “Connecting the Supervisor CMP Port” section.

Step 21 If you need to upgrade the other supervisor module to 8 GB (both modules must have the same amount of memory), repeat Steps 2 through 19.

Step 22 Verify that the upgraded module has 8 GB of memory. If there are two supervisor modules installed in the switch, use the system switchover command to make that module active, and then use the show system resources command. If there is just one supervisor module installed in the switch, use the show system resources command.

Step 23 If you need to upgrade another supervisor module to 8 GB (both supervisor modules in a switch with two supervisors must have the same amount of memory), repeat Steps 2 through 22.


 

Removing 4 GB of Memory from a Supervisor Module

If you need to remove 4 GB of memory from the supervisor modules so that they each have only 4 GB of memory, you must remove the DIMM from the second memory slot from the front of each installed supervisor module.


Note If the switch has two supervisor modules, both must have the same amount of memory. If you downgrade one supervisor module to 4 GB of memory, you must also downgrade the other supervisor module to 4 GB of memory.


To remove 4 GB of memory from a supervisor module, follow these steps:


Step 1 Follow ESD procedures, which include wearing an ESD wrist strap and placing antistatic foam or antistatic padding where you will place the supervisor module while working with it.

Step 2 Disconnect the cables attached to the front of the module to be removed. If there are two supervisor modules installed in the switch, disconnect the cables from the standby supervisor.


Note If the chassis has two supervisor modules and you disconnect the active supervisor module, that supervisor goes into standby mode and the other supervisor becomes the active supervisor.


Step 3 Loosen and fully unscrew both captive screws on the installed supervisor module that you need to upgrade.

Step 4 Press both ejector release buttons on the ends of the module (see Callout 2 in Figure 10-5) to push out the ejector levers and to disconnect the module.


Note If you stop this procedure at this point without removing the module and need to power it up, simultaneously press both ejector levers back to the face of the module until they click, secure both of the module captive screws to the chassis, and then use the no poweroff module slot_number command to power up the module.


Step 5 Simultaneously rotate the two ejector levers outward to unseat the module from the midplane connector (see Callout 3 in Figure 10-5).

Step 6 With a hand on each ejector lever, pull the module part way out of its slot in the chassis.

Step 7 Grasp the front edge of the module with one hand and place your other hand under the lower side of the module to support its weight. Pull the module out of its slot.


Caution To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming in contact with its circuitry.

Step 8 If you are removing the module from a Cisco 7010 chassis, rotate the module 90 degrees counterclockwise so that it is horizontal and you can see the circuitry from above.

Step 9 For the DIMM in the second memory slot from the front of the supervisor module, rotate the two spring clips away from the DIMM (see Callout 1 in Figure 10-10).

Figure 10-10 Removing a 4-GB DIMM

 

1

On the second socket from the front of the module, rotate both spring clips away from the DIMM.

3

Remove the “8 GB” label on the front of the module.

2

Hold the DIMM by its edges and pull it out of the memory slot.

Step 10 Holding the edges of the 4-GB DIMM with your fingers, slide it out of its memory slot (see Callout 2 in Figure 10-10) and place it in an antistatic bag.

Step 11 Remove the 8-GB label from the front of the module.

Step 12 Rotate both ejector levers away from the front of the supervisor module.

Step 13 Grasp the front of the module with one hand and place your other hand under the module to support its weight.

Step 14 Align the module to the open supervisor slot in the chassis and push the module into the slot until it makes contact with the midplane.

Step 15 Simultaneously push both ejector levers inward until they come in contact with the face of the module.

Step 16 The module should be fully seated in the slot and the captive screws should be aligned with their holes in the chassis. The EMI gasket should close the gap between this module and the next module.

Step 17 Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9 N·m).

Step 18 Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the “Connecting to the Console” section.

Step 19 If the previous supervisor module was connected to an asynchronous device through a modem, connect the modem cable to the COM1/AUX SERIAL PORT as explained in the “Connecting to the Console” section.

Step 20 Reconnect the network management cable to the MGMT ETH port as explained in the “Setting Up the Management Interface” section.

Step 21 Reconnect the CMP cable to the CMP MGMT ETH port as explained in the “Connecting the Supervisor CMP Port” section.

Step 22 Verify that the module has 4 GB of memory by using the system switchover command to make the downgraded module active and using the show system resources command.

Step 23 If you need to downgrade the other supervisor module to 4 GB (both modules must have the same amount of memory), repeat Steps 2 through 21.

Step 24 Verify that the downgraded module has 4 GB of memory. If there are two supervisor modules installed in the switch, use the system switchover command to make the downgraded module active, and then use the show system resources command. If there is just one supervisor module installed in the switch, use the show system resources command.

Step 25 If you need to downgrade another supervisor module to 4 GB (both supervisor modules in a switch with two supervisors must have the same amount of memory), repeat Steps 2 through 24.


 

Installing an I/O Module

A Cisco Nexus 7004 switch has up to two I/O modules, a Cisco Nexus 7009 switch has up to seven I/O modules, a Cisco Nexus 7010 switch has up to eight I/O modules, and a Cisco Nexus 7018 has up to 16 I/O modules. These modules are located on the front of the chassis. You can replace one of these modules at a time while the switch is operating.


Note If you are installing F2 I/O modules, all of the fabric modules in the switch must be Series 2 fabric modules.


This section describes how to replace I/O modules and includes the following topics:

Required Tools

You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screws on the I/O module.

Installing a New I/O Module

A Cisco Nexus 7000 Series switch includes one or more of the following types of I/O modules:

  • 48-port 10/100/1000 Ethernet module (N7K-M148GT-11)
  • 48-port 10/100/1000 Ethernet module with XL option (N7K-M148GT-11L)
  • 48-port 1-Gigabit Ethernet I/O module (N7K-M148GS-11)
  • 48-port 1-Gigabit Ethernet I/O module with XL option (N7K-M148GS-11L)
  • 48-port 1-/10-Gigabit Ethernet I/O modules with XL (N7K-F248XP-25 and N7K-F248XP-25E)
  • 32-port 10-Gigabit Ethernet I/O module (N7K-M132XP-12)
  • 32-port 10-Gigabit Ethernet I/O module with XL option (N7K-M132XP-12L)
  • 32-port 1- and 10-Gigabit Ethernet I/O module (N7K-F132XP-15)
  • 8-port 10-Gigabit Ethernet I/O module with XL option (N7K-M108X2-12L)

You can replace each of these I/O modules with another module of the same type while the Cisco Nexus 7000 Series switch is operational. To do this action, you must first remove an I/O module from the chassis, and then install a new or replacement I/O module in the newly vacated slot within a couple of minutes to maintain the designed airflow.


Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution Make sure that you wear an ESD wrist strap while you handle each I/O module. Hold the module only on its carrier edges without touching any electronic circuitry, and place it on antistatic mats or repack it in its original packing material when it is not installed in the chassis.


Caution If you cannot immediately replace an I/O module, either leave the I/O module in its slot or replace it with a blank module so the system airflow is not disrupted. Leaving an I/O module slot open for more than a couple of minutes can disrupt the system airflow causing the system to overheat and shut down.

To replace an I/O module, follow these steps:


Step 1 Place antistatic mats or antistatic foam where you can place the old and new I/O modules. Choose a place that prevents damage to the module while it is outside the chassis.

Step 2 Unpack and place the replacement I/O module on an antistatic mat or antistatic foam.

Step 3 Disconnect each I/O cable from the front of the module by doing the following:

    • For the 48-port 10/100/1000 Ethernet I/O module (N7K-M148GT-11 and N7K-M148GT-11L), unplug each cable.
    • For the 48-port 1-Gigabit Ethernet types of I/O modules (N7K-M148GS-11 and N7K-M148GS-11L) and the 48-port 1- and 10-Gigabit Ethernet I/O module (N7K-F248XP-25), remove the fiber-optic cables and then remove the SFP transceivers.
    • For the 32-port 10-Gigabit Ethernet types of I/O modules (N7K-M132XP-12, N7K-M132XP-12L, and N7K-F132XP-15), remove the fiber-optic cables and then remove the SFP+ transceivers.
    • For the 8-port 10-Gigabit Ethernet I/O module (N7K-M108X2-12L), remove the fiber-optic cables and then remove the X2 transceivers.

Note To prevent contaminants from entering the fiber-optic lines or transceivers, cover the fiber-optic openings with a plug.



Warning Invisible laser radiation may be omitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051


Step 4 Loosen the two captive screws identified in View A of Figure 10-11.

Step 11 On the replacement I/O module, rotate both ejector levers fully away from the front of the module.

Step 12 If you are inserting the module into a Cisco Nexus 7010 chassis, rotate the module 90 degrees clockwise.

Step 13 Align the module to the chassis guides for the vacated slot, and slide the module part way into the slot.

Step 14 With one or both hands on the front of the module, push the module all the way into the slot until it seats on the midplane connector.

Step 15 Simultaneously push both ejector levers inward until they come in contact with the face of the module.


Note Verify that the ejector levers are fully closed before tightening the captive screws. Failure to fully seat the module in the backplane connector can result in error messages.


Step 16 Tighten the two captive screws on the I/O module to 8 in-lb (0.9 N·m).

Step 17 Reconnect the I/O cables to the ports or the transceivers on the fiber-optic cables to the ports on the module.


 

Installing a NAM Module

The Network Analysis Module (NAM) can be installed in an I/O module slot on the Cisco Nexus 7004, 7009, 7010, or 7018 switch chassis. You can either replace a NAM or install a new one in an empty I/O module slot. If you install a new module, you must also install and configure the latest NAM software on the module.


Note If the switch shipped with one or more NAM modules already installed, then the modules are already configured with the Prime NAM software and are ready to be used. If you are installing a new NAM module and the module does not automatically boot up, then you must install and configure the Prime NAM software in order to use the module.


This section describes how to install NAM modules and includes the following topics:

Required Tools for Installing a NAM

You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screws on the I/O module.

Installing or Replacing a NAM

A Cisco Nexus 7004, 7009, 7010, or 7018 switch can have one or more NAMs installed in it. You can either install a new one in an empty I/O module slot or replace an existing NAM or I/O module. If you are replacing an existing NAM, you must first shut down the module with the out-of-service module command before removing the original module. If you are replacing an I/O module, you can either use the out-of-service module command to shut the module down or just remove the module and a graceful shutdown will automatically occur.


Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution To prevent ESD damage, wear an ESD wrist strap while you handle each module. Hold the module only on its carrier edges without touching any electronic circuitry, and place it on antistatic mats or repack it in its original packing material when it is not installed in the chassis.


Caution If you cannot immediately replace a NAM, either leave the module in its slot or replace it with a blank module so the system airflow is not disrupted. Leaving an I/O module slot open for more than a couple of minutes can disrupt the system airflow causing the system to overheat and shut down.

To install or replace a NAM, follow these steps:


Step 1 Place antistatic mats or antistatic foam where you can place the old and new I/O modules. Choose a place that prevents damage to the module while it is outside the chassis.

Step 2 Unpack and place the new I/O module on an antistatic mat or antistatic foam.

Step 3 If you are installing a new NAM in an empty slot, remove the blank filler plate that is in the slot by unscrewing its captive screws and pulling the plate off the chassis. Go to Step 5 to continue the installation.

Step 4 To remove an existing NAM, follow these steps:

a. Shut down the module by using the out-of-service module command with the NX-OS CLI.

switch(config)# out-of-service module 2
switch(config)#

Note Alternatively, you can use the poweroff module command, but that command requires that you use the no poweroff module command after reinstalling the module. If you use the out-of-service module command, you do not need to use another command to bring the module up when you install it.


b. Disconnect any cables attached to the front of the module.

c. Loosen the two captive screws (one on each end of the module) until they are no longer in contact with the chassis.

d. Press ejector release buttons on each end of the module to push out the ejector levers.

e. Simultaneously rotate the two ejector levers outward to unseat the module from the midplane connector.

f. With a hand on each ejector, pull the module part way out of its slot in the chassis.

g. Grasp the front edge of the module and place your other hand under the module to support its weight. Pull the module out of its slot. Do not touch the module circuitry.

h. If you are removing the module from a Cisco Nexus 7010 chassis, rotate the module 90 degrees counterclockwise so that it is horizontal (with the electronics seen from above).

i. Place the module on an antistatic mat or repack it in its original packing materials.

Step 5 Install the new NAM as follows:

a. On the replacement NAM, rotate both ejector levers fully away from the front of the module. If necessary, press the two ejector buttons to release the levers from the front of the module and then rotate the levers away from the front of the module.

b. If you are inserting the module into a Cisco Nexus 7010 chassis, rotate the module 90 degrees clockwise so that the circuitry is seen from the right side.

c. Align the module to the chassis guides for the open slot, and slide the module into the slot until it stops with the front of the module being about 1/4 inch (0.6 cm) out from the front of the chassis.

d. Simultaneously push both ejector levers inward until they come in contact with the face of the module. The module moves completely into the slot with the front of the module being at the front of the chassis.

e. Verify that the ejector levers are fully closed before tightening the captive screws. Failure to fully seat the module in the midplane connectors can result in error messages or damage to the module.

f. Tighten the two captive screws on the I/O module to 8 in-lb (0.9 N·m) of torque.

g. If you disconnected any cables from the front of the module, reconnect those cables to the module.

h. Verify that the STATUS LED eventurally turns green to show that the module is operational. For information on the other states indicated by this LED, see the “NAM-NX1 Module LEDs” section.


 

You are ready to install the Prime NAM software on the new module.

Installing the Cisco Prime NAM Software

To install the Cisco Prime NAM software, follow these steps:


Step 1 Use a browser to go to http://software.cisco.com/download/navigator.html.

The Software Download page opens.

Step 2 Choose Cloud and Systems Management > Network Analysis Module (NAM) Products > Cisco Prime Network Analysis Module Software > Cisco Prime Network Analysis Module Software 6.2 (or later verssion). A list of software files appears.

Step 3 Click the Download button for the software file name beginning with nam-nx1. The filename is nam-nx1. x-x-x .bin.gz (where x-x-x is the NAM software release number).

Step 4 Using the NAM CLI, enter the upgrade command to specify the user, password, server,path to the file, and installation file name. For example, for the admin user, “secret” password, server IP address 10.10.10.10, archive/nam_software path, and nam-nx1.6.0.1.bin.gz installation file, you would use the upgrade command as follows:

upgrade ftp://admin:secret!10.10.10.10//archive/nam_software/nam-nx1.6.0.1.bin.gz


 

Configuring the NAM

To configure the NAM software, you must do all of the following:

Configuring a VLAN Management Port for the NAM

Using the virtual device context (VDC) that the NAM belongs to, you must configure a VLAN for NAM management traffic, and you must assign that VLAN to the NAM management port.

To configure and assign a VLAN management port, follow these steps:


Step 1 Verify that the NAM is active.

switch# show service nam summary
Service Service
Name Type Interface Module State Version
---------------- ----------- -------------- --------- --------- ---------------
NAM7 NAM Po4096, Po4095 7 active 6.0

Step 2 Allocate the NAM interfaces to the VDC as follows:

  • If you are using the default VDC configuration, the NAM interfaces should be allocated to the default VDC automatically. Verify that allocation.
switch(config)# show run vdc
!Command: show running-config vdc
!Time: Wed May 29 18:47:17 2013
 
version 6.2(2)
no system admin-vdc
vdc N7K-8 id 1
limit-resource module-type m1 m1x1 m2x1 f2e
  • If you are not using the default VDC configuration,

Step 3 If a VLAN does not already exist for the NAM, create the VLAN.

switch(config)# config t
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# vlan 200
switch(config-vlan)# state active
switch(config-vlan)# no shut
switch(config-vlan)# exit
switch(config)#

Step 4 Add the VLAN to the external interface that will be used to access the NAM by specifying the interface.

switch(config)# int e4/48
switch(config-if)# switchport
switch(config-if)# switchport mode access
switch(config-if)# switchport access vlan 200
switch(config-if)# no shut
switch(config-if)# exit
switch(config)#
 

Step 5 Assign the VLAN to the management port for the NAM module by using the analysis module command.

switch(config)# analysis module 7 management-port 1 access-vlan 200
switch(config)# exit
switch#


 

After you have configured a VLAN management port for the NAM, you need to set up a SPAN session to define the switch as the traffic source and the NAM as the traffic destination. You can set up a SPAN session in either one of following ways:

Configuring a SPAN Session for a Data Port

To use the NAM with a switch, you must define a SPAN session between the switch and the NAM. You can specify the switch by its interface and specify the NAM by its data port.

If you need to define the NAM by the port channel used, see the “Configuring a SPAN Session for a Port Channel” section.

Specifying the NAM IP Configuration and Enabling the Web Server

After you assign the NAM to a VDC and set up a SPAN session between the switch and the NAM, you must go to the VDC for the NAM, set up the IP configuration for the NAM, and enable the web server. You can enable the NAM to function as either an HTTP server or an HTTPS secure server, but not both simultaneously. After you enable the web server, the NAM is functional.


Step 1 Use the Cisco NX-OS attach module slot_number processor number command to open a span session.

attach module slot_number processor 1
Example:
switch# attach module 3 processor 1
opening...

System Alert: Default password has not been changed!
Please enter a new password:

 


Tip Ensure that you are in the correct VDC. To switch to another VDC, you can use the switchto vdc command.


If you have not changed your password, you will be prompted to enter a new password.

Step 2 If you need to enter a new password, enter the password twice.

Please enter a new password:
Confirm new password:
Successfully changed password for user ‘root’

 

Step 3 Enable either an HTTP or HTTPS server.

  • To enable an HTTP server, use the ip http server enable command.
root@nam.localdomain# ip http server enable
No web users are configured.
Please enter a web administrator username [admin]:
  • To enable an HTTPS server, use the ip http secure server enable command.
root@nam.localdomain# ip http secure server enable
No web users are configured.
Please enter a web administrator username [admin]:
 

Step 4 Enter the web admin username and password.

User admin added.
Starting httpd
root@nam.localdomain

Tip We recommend that you change the admin password. All default passwords should be changed as soon as possible.


Step 5 If you need to use a Telnet or SSH client, do one of the following:

  • To use a Telnet client, use the excession on command.
root@nam.localdomain# exsession on
  • To use an SSH client, use the exsession on ssh command.
root@nam.localdomain# exsession on ssh

Step 6 Verify network connectivity to an known IP address by using the ping ip_address command.

root@nam.localdomain# ping 3.3.3.3

Step 7 Use an approved Firefox or Internet Explorer browser to access the NAM and confirm connectivity. For a list of approved browsers, see the Cisco Prime NAM Release Notes.

If the Cisco Prime NAM web server is properly configured, you can access the NAM login window.


 

At this point, the only user able to log into the NAM web server is the administrative user that you configured when you enabled the web server. There is no secondary user option. To configure additional users, see the Prime NAM Command Reference Guide or the Prime NAM User Guide on Cisco.com.

Upgrading the Cisco Prime NAM software

If you need the latest version of the Cisco Prime NAM software, see the “Installing the Cisco Prime NAM Software” section.

Replacing a Cisco Nexus 7009 Fabric Module During Operations

The Cisco Nexus 7009 switch has up five fabric modules located on the front of the chassis. You can replace one of these fabric modules at a time while the switch is operating.

You should replace a fabric module with another fabric module within a couple minutes to maintain the designed system airflow. If you cannot replace the fabric module, you must fill the slot with a blank module.


Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution Make sure that you wear an ESD wrist strap while you handle each fabric module. Hold the module only on its carrier edges without touching any electronic circuitry, and place it on antistatic mats or repack it in its original packing materials when it is not installed in the chassis.

To replace a fabric module, follow these steps:


Step 1 Place an antistatic mat or antistatic foam where you can place the fabric modules. Choose a place that prevents damage to the module while it is outside the chassis.

Step 2 Unpack and place the replacement fabric module on the antistatic mat or antistatic foam.

Replacing or Upgrading a Cisco Nexus 7010 or 7018 Fabric Module During Operations

The Cisco Nexus 7010 and 7018 switches have up to five fabric modules located on the back of the chassis. You can replace one of these fabric modules at a time while the switch is operating. You can also upgrade all of the Fabric 1 modules with Fabric 2 modules, which provide increased performance (when all of the operational fabric modules are Fabric 2 modules) and are recommended for F2 I/O modules.

This section describes how to replace fabric modules and includes the following topics:

Required Tools

You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screws on the fan tray.

Replacing a Cisco Nexus 7010 or 7018 Fabric Module

You should replace a fabric module with another fabric module within a couple of minutes to maintain the designed system airflow. If you cannot replace the fabric module, you must fill the slot with a blank module. If you are replacing Fabric 1 modules with Fabric 2 modules, see the “Upgrading Fabric 1 Modules with Fabric 2 Modules” section.


Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution Make sure that you wear an ESD wrist strap while you handle each fabric module. Hold the module only on its carrier edges without touching any electronic circuitry, and place it on antistatic mats or repack it in its original packing materials when it is not installed in the chassis.

To replace a fabric module, follow these steps:


Step 1 Place an antistatic mat or antistatic foam where you can place the fabric modules. Choose a place that prevents damage to the module while it is outside the chassis.

Step 2 Unpack and place the replacement fabric module on the antistatic mat or antistatic foam.

Step 3 Loosen the two captive screws on the module that you are removing (see View A in Figure 10-14).

Upgrading Fabric 1 Modules with Fabric 2 Modules

If you are running Cisco NX-OS 6.0(x) or a later release, you can upgrade all of the Fabric 1 modules with Fabric 2 modules in a Cisco Nexus 7010 or 7018 switch (the Cisco Nexus 7009 uses only Fabric 2 modules). You can upgrade the modules during operations if you replace each within a couple of minutes so that the switch can maintain its designed airflow. The upgrade process is non disruptive to switch operations if there is at least one fabric module installed and operating in the switch while you upgrade another fabric module.

When upgrading fabric modules, you must replace all of the Fabric 1 modules in the switch with Fabric 2 modules within 12 hours or you will see a syslog message that reminds you to complete the upgrade.


Note If you power up a switch that has both types of fabric modules installed, only the Fabric 2 modules power up. If you need the Fabric 1 modules to power up, you must first power off all of the Fabric 2 modules (see the “Shutting Down a Fabric Module” section) before the Fabric 1 modules can power up.



Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution Make sure that you wear an ESD wrist strap while you handle each fabric module. Hold the module only on its carrier edges without touching any electronic circuitry, and place it on antistatic mats or repack it in its original packing materials when it is not installed in the chassis.

To upgrade Fabric 1 modules with Fabric 2 modules, follow these steps:

Replacing the Front Door and Air Intake Assemblies on the Cisco Nexus 7018 Chassis

If you are going to move the Cisco Nexus 7018 chassis or if you need to replace the door and air intake assembly, you must first remove the installed door and air intake assemblies.


Note For the double-hinged door to easily open or close in either direction, make sure that the chassis is level. If necessary, remove the chassis from the rack and adjust the bottom-support rails so that the chassis is level. Also, make sure that the cable management assemblies are aligned to the vertical sides of the chassis and that the cable management top cover is level when you install those components.


This section includes the following topics:

Removing the Front Door and Air Intake Assemblies

When you remove the front door and air intake assemblies, you remove the door, air intake assembly, and the hardware used to hold those components to the chassis.

To remove the front door and air intake assemblies on the Cisco Nexus 7018 chassis, follow these steps:


Step 1 Remove the front door by following these steps:

a. Open the door by pulling one of its latch handles out until it clicks (the handle clicks when you pull it out about 30 degrees) and rotating the door away from the chassis (see Callouts 1 and 2 in Figure 10-35).

To replace the front door and air intake assemblies, see the “Installing a Front Door and Air Intake Assemblies” section.

Installing a Front Door and Air Intake Assemblies

When you install a front door and air intake assembly components, you install hardware to hold the door and air intake assemblies, attach the door, and then attach the air intake assembly.

To install the front door and air intake assembly components, follow these steps:


Step 1 Open the Front Door and Air Intake kit (69-1962-01) and verify that it includes the following components:

  • 1 front door (800-31268-01)
  • 1 air intake frame (800-31270-01)
  • 1 bottom hinge bracket (700-28491-02)
  • 1 left door stopper (has an L on its base) (700-27454-01)
  • 1 right door stopper (has an R on its base) (700-27592-01)
  • 8 M4x8 pan head screws (48-0398-01)
  • 4 M3x14 pan head screws (48-1699-01)
  • 4 ball-point studs (51-5171-01)

Step 2 Position the left door stopper (has an L on its base) on the middle of the left side of the cable management frame and fasten it with two M3x14 pan-head screws as shown in Figure 10-43. Tighten these two screws to 8.4 to 11 in-lb (0.9 to 1.2 N·m).

Step 11 Fasten the captive screws on the air intake frame to the chassis and tighten to 11 to 15 in-lb (95 to 130 N·m).

Step 12 On the chassis door, pull the door handle open on one of the two sides of the door until the handle clicks (the handle clicks when you pull it out about 30 degrees).

Step 13 Move the side of the door with the opened handle onto the two hinge pins as shown in Figure 10-49. Make sure that the hinge pins on the top cover and bottom hinge bracket fit through the slots on the top and bottom of that side of the door. Position the door so the hinge pins are located at the ends of the slots.


Note The double-hinged door can be installed and opened on either side. The figures in this procedure show how to install the door on the left side first, but you can use the instructions to install it on either side first.

Step 16 Swing the door closed so that the remaining two pins on the bottom hinge bracket and top cover fit inside the slots on the top and bottom of the door. When you close the door, the door stopper automatically presses the lock button on the inside of the door so that the door is locked on the hinge pins. If the door stopper does not close the latches, press the door closed at the handle until you hear the latches click. Make sure that the door is fully secured to the frames on both sides.


Note If a hinge pin is not secured behind a door latch, open the door handle for that side of the door until it clicks, open that side of the door, and then press the door closed so that the pins are positioned all the way inside the door slots. When you close the door, the door stopper automatically closes the door latches. If you do not hear the latches click, press the door at the handle to fully close it and to activate the latches. Test the door to make sure that it is fully secured to the four hinge pins.



Tip Whenever you need to open the door, pull one of the latch handles open until it clicks and then swing that side of the door open.



Note If the double-hinged door and its holders are not level, it is possible that you will have some difficulty opening or closing the door on one or both sides without the door being defective. Either push in the bottom portion of the door or slightly lift up the door on that side just before closing. If the problem persists, open the door from the other side, which should be free of this problem, or adjust the cable management system and hinge bracket so that they are level.



 

Replacing the Air Filter on the Cisco Nexus 7004 Chassis

You can replace the optional air filter while the Cisco Nexus 7004 system is operational.


Note We recommend that you check the air filter once a month. If it is covered with a significant amount of dust, replace the air filter.


To replace the air filter, follow these steps:


Step 1 On the right side of the chassis, remove eight screws that hold the airfilter to the chassis.

Step 2 Remove the air filter.

Step 3 Place the new air filter over the air intake area on the right side of the chassis and align the eight screw holes in the filter to screw holes in the chassis.

Step 4 Fasten the air filter to the chassis using eight M3 x 5 mm screws that came with the air filter.. Tighten the screws to 5 to 7 in-lb (0.56 to 0.79 N.m).


 

Cleaning or Replacing the Air Filter for the Cisco Nexus 7010 Chassis

You can clean or replace the optional air filter while the Cisco Nexus 7010 system is operational.


Note We recommend that you check the air filter once a month. If it is covered with an oily substance, you should replace it. If it is covered with dust, you can clean it and continue to use it.


To clean or replace the air filter, follow these steps:


Step 1 On the left and right side of the existing air filter, loosen the two captive screws so they are no longer attached to the chassis. The air filter can be found covering the air intake area at the bottom of the front side of the chassis (see Figure 1-5).

Step 2 With one hand holding the air filter in place, use the other hand to pull out the spring pin on one side of the air filter. Pull that side of the air filter away from the chassis and release the spring pin when it is clear of the bracket on the EMI frame.

Step 3 Switch the hands holding the air filter and use the other hand to pull out the spring pin on the other side of the air filter. Pull the air filter away from the chassis and release the spring pin.

Step 4 If the filter is covered with an oily substance, we recommend that you replace it. If the filter is dusty, you can take it outside the data center and clean it in one or more of the following ways:

  • Use a vacuum cleaner over both sides of the filter.
  • Blow compressed air through the exhaust side of the filter.
  • Rinse the filter with cold water.
  • Immerse the filter in warm, soapy water, and then rinse it.

Note If the filter gets wet while you clean it, make sure that it dries before you reinstall it.


Step 5 Align the cleaned or replacement air filter to the EMI frame covering the air intake area.

Step 6 Use one hand on the air filter to hold it in place while you use the other hand to pull out the spring pin on one side of the air filter. Adjust the air filter so that the spring pin will be released into its hole in the EMI frame bracket.

Step 7 Switch the hands holding the air filter and use the other hand to pull out the other spring pin on the other side of the air filter. With the spring pin pulled out, position the air filter so that the pin will be released into its hole on the EMI frame bracket. Release the spring pin and make sure that it holds the air filter on to the EMI frame.

Step 8 Screw in and tighten both captive screws, one on each side of the air filter.
