Replacement Procedures
This chapter describes the replacement procedures for the Cisco Nexus 7000 Series switch components.
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.

Replacing a Power Supply Unit During Operations
The Cisco Nexus 7000 Series switches use a load-balanced power supply that uses up to three or four power supply units that each convert up to 1.2 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 remove and install redundant power supply units and includes the following topics:

Removing a Power Supply Unit During Operations
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
To replace a power supply unit while a Cisco Nexus 7000 Series switch is operating, follow these steps:
Step 1 Make sure that the power supply units not being replaced have their power switches turned to ON.
Step 2 Turn the power switch on the power supply that you are removing to standby (STBY).
The Input 1 and Input 2 LEDs turn off.
Note If the power supply has only one AC power cord attached to it, only the LED for that input line turns off (the other one is already off).
Step 3 Unplug the AC power cords from the AC power source. If the power supply unit has only one AC power cable, unplug just that cable. Otherwise, unplug both AC power cables.
Step 4 Unscrew the four captive screws on the power supply unit until each screw is no longer in contact with the chassis.
Step 5 Grasp the power supply handle with one hand and slide the power supply part of the way out of the chassis. Place your other hand underneath the power supply unit and slide the power supply unit completely out of the chassis.
Step 6 Place the power supply unit on an antistatic mat or repack it in its original shipping materials.
Step 7 Either replace the power supply unit or cover the empty power supply bay as follows:
•If you are ready to replace the power supply unit, see the Installing a Power Supply Unit During Operations.
•If the power supply bay is to remain empty, install a blank power supply filler plate (Cisco part number 800-28658-01) over the opening, and secure it with the captive screws.
Installing a Power Supply Unit During Operations
After you remove a power supply, you can replace it with another power supply or replace it with a blank plate until another power supply is available.
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
To install a 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, the power cord is 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 If the power cords are not already attached to the power supply unit, plug the power cables into the power jacks on the front of the power supply unit and tighten the cable retention devices for each cable. Depending on the amount of power consumed by the power supply unit, you need to attach one or two power cords.
Note The 6-kW 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 power supply unit that you removed. The 7.5-kW power supply ships with permanently attached power cables, so you do not need to attach power cables to that power supply unit.
Step 4 Grasp the power supply unit handle with one hand, and place your other hand underneath the power supply unit to support its weight. 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 power supply unit weighs 22 pounds (10 kg), and the 7.5-kW power supply unit weighs 26.4 pounds (12 kg). Use two hands to safely hold and move a power supply unit.
Step 5 Screw in and tighten the four captive screws so the power supply unit is secured to the switch chassis.
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 blinking.
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 (STDBY), and then turn the power switch back to ON. The LEDs for the connected power supply units should be green.
For more information on the power supply unit LED states, see Table C-5 on page C-5.
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.
This section describes how to replace supervisor modules and includes the following topics:
•Required Tools
•Replacing One of Two Supervisor Modules During System Operations
•Replacing a Supervisor Module in a Single-Supervisor System
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 One of Two Supervisor Modules During System Operations
During operations, one supervisor is active while the other 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.
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 8-1 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 8-1 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 8-2.

•If you are removing an expansion flash card, you will see the following message:
switch# 2008 Mar 15 10:00:00 switch %$ VDC-1 %$ %IDEHSD-2-UMOUNT:slot0:offline
Step 3 Press the Eject button next to the reader.
The reader ejects the card part way out of the slot.
Step 4 Remove the card from the reader.
Step 5 Align the replacement card to the CompactFlash reader slot as shown in Figure 2-10 on page 2-17. The grooves on the thin side of the card must begin on the end of the card that goes into the reader first.
Step 6 Push the card all the way into the reader.
If the card does not fit easily into the slot, flip the card so the bottom edge is on top, and try pushing the card into the slot.
Step 7 Wait for the reader LED to turn green and for a message to appear on the console.
•If you are installing a card into the log flash reader, the message will end with "logflash:online."
switch# 2008 Mar 15 08:00:00 switch %$ VDC-1 %$ %IDEHSD-2-MOUNT: logflash:online
•If you are installing a card into the expansion flash reader, the message will end with "slot0:online."
switch# 2008 Mar 15 08:00:00 switch %$ VDC-1 %$ %IDEHSD-2-MOUNT: slot0:online
•If you see an offline message or do not see a message, either the card is not fully pushed into the reader or it is improperly formatted.
switch# 2008 Dec 1 12:00:00 switch %$ VDC-1 %$ %IDEHSD-2-UMOUNT:logflash:offline
Make sure that the card is fully inserted inside the reader. If the card is fully inserted, either format the card (see the Cisco NX-OS Fundamentals Configuration Guide, Release 4.1) or replace the card with another card that is properly formatted for the reader.
Replacing the Front Doors and Frame Assembly on the Cisco Nexus 7010 Chassis
If the front door and frame assembly are already attached to the chassis when you need to ship the chassis or move the chassis from one rack to another, you should remove the front doors and frame assembly for safer and easier handling of the chassis.
This section describes how to remove and install the front doors and frame assembly, and it includes the following topics:
•Required Tools
•Removing the Front Doors and Frame Assembly
•Installing the Front Doors and Frame Assembly
Required Tools
You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the screws that hold the frame members to the chassis.
Removing the Front Doors and Frame Assembly
Removing the optional front doors and frame assembly involves removing the side frames from the EMI frame, removing the bottom frame assembly, and removing the two front doors.
Note If you are installing a new chassis, you do not need to perform this task because the chassis is not shipped with these assemblies attached to it.
To remove the front doors and frame assemblies, do the following:
Step 1 Remove the two lower side frames from the EMI air filter frame by first removing the EMI panel from the chassis, then unscrewing the side frame pieces. When done, replace the EMI frame on the chassis. The following steps explain each of these tasks.
a. On the EMI panel, which covers the air intake area on the lower front side of the chassis, loosen and completely unscrew each of the four captive screws that hold the panel to the chassis.
b. Pull the EMI panel away from the chassis, along with the attached side frame members and optional air filter (if attached) (see Figure 8-6).

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 7010 Chassis
You can replace the optional air filter while the Cisco Nexus 7010 system is operational.
Note Only the Cisco Nexus 7010 chassis includes an optional air filter.
To 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 1-2 on page 1-3).
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 Align the replacement air filter to the EMI frame covering the air intake area.
Step 5 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 6 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 7 Screw in and tighten both captive screws, one on each side of the air filter.
