Preparing for an Upgrade


Note Cisco IOS Release 12.2 changed the behavior of the ROM monitor (ROMmon) during the bootup sequence. See the "Boot Changes in Cisco IOS Release 12.2" section on page 10-2 for more information.


Upgrading to the NPE-G1 or NPE-G2 is a different procedure than previous processor upgrades because of the following considerations:

The NPE-G1 and NPE-G2 contain an I/O controller, which includes the bootflash and NVRAM memory. After you install the NPE-G1 or NPE-G2 in a chassis, you can no longer access the bootflash and NVRAM on the I/O controller. You therefore must make the existing Cisco IOS software image and configuration files available to the NPE-G1 or NPE-G2, either by putting these files on a CompactFlash Disk or on a TFTP server.

The NPE-G1 and NPE-G2 include three Gigabit Ethernet interfaces. If you want to use these interfaces to replace the Ethernet or Fast Ethernet interfaces on the existing I/O controller, you must configure the new interfaces before they can be used to access the network. If you are also removing the existing I/O controller, you must remove the configuration for its Ethernet or Fast Ethernet interfaces.


Note The NPE-G2 provides a Fast Ethernet Management port, as well as three RJ-45 Gigabit Ethernet ports.


The NPE-G1 and NPE-G2 use Type 1 CompactFlash Disk memory instead of the Type 2 Flash Disk memory used in existing I/O controllers. You must transfer any information currently saved on Flash Disks to CompactFlash Disks so that it can be used after the upgrade to the NPE-G1 or NPE-G2.


Note If you are upgrading to an NPE-G2 from an NPE-G1, you do not need to perform the following procedure.


To ensure a smooth upgrade, perform the following procedure only if you are upgrading to an NPE-G1 or NPE-G2 from an NPE-400 or earlier network processing engine.

Before you install an NPE-G1 or NPE-G2 in an existing router and remove the existing processor and I/O controller, do the following:


Step 1 Copy the configuration file from the existing router to a TFTP server, Flash Disk, or PC Card. See the "Copying the Configuration File" section for details.

Step 2 Modify the configuration file to accommodate the new Gigabit Ethernet interfaces on the NPE-G1 or NPE-G2. If you are also planning to remove the I/O controller, also remove the configuration lines for the Ethernet or Fast Ethernet interfaces on the I/O controller. See the "Configuring the Native Gigabit Ethernet Interfaces" section for guidelines.

Step 3 Copy the modified configuration file to a CompactFlash Disk that can be used on the NPE-G1 or NPE-G2. If you are not planning on removing the existing I/O controller, you can do this by copying the configuration to a Flash Disk, as described in Step 1, before you install the NPE-G1 or NPE-G2. Then you can keep the Flash Disk in the I/O controller and copy it to a CompactFlash Disk in the NPE-G1 or NPE-G2 after you have finished installing the NPE-G1 or NPE-G2.

If you are planning on removing the existing I/O controller, you can copy the configuration file to a CompactFlash Disk in the following ways:

Copy the configuration file to a TFTP server and then copy it to a CompactFlash Disk on an existing NPE-G1 or NPE-G2.

Copy the configuration file to a Type 2 Flash Disk using the existing I/O controller, as described in the "Copying the Configuration File to a Flash Disk or PC Card" section. Then use a multi-function reader that accommodates both Type 1 CompactFlash Disk and Type 2 Flash Disk memory cards to transfer the configuration file to the CompactFlash Disk.

Use a Type 1-to-Type 2 adapter to convert the CompactFlash Disk to the Flash Disk form factor. Then insert the CompactFlash Disk and adapter into the existing I/O controller and copy the configuration file to it, as described in Step 1.


Note The CompactFlash Disk must be formatted before you can write any files to it. The CompactFlash Disk shipped with the NPE-G1 or NPE-G2 is already formatted, but a spare CompactFlash Disk must be formatted using the format command. Do not format the CompactFlash Disk in a PC or other workstation because the router cannot use CompactFlash Disks that are formatted by other computers. After the CompactFlash Disk is properly formatted, however, you can write to it using any PC or workstation that recognizes Type 2 CompactFlash Disk memory.


Step 4 (Optional) Copy the proper Cisco IOS software image (see Table 8-4 on page 8-4) to the CompactFlash Disk, using the same technique you used to copy the configuration file in Step 3. You do not need to perform this step if you plan to boot the router from a TFTP server, but you must add the proper boot configuration command to the configuration file when you modify it in Step 2.


Copying the Configuration File


Caution Before powering down the router to install the NPE-G1 or NPE-G2, you must save the current configuration to a Flash Disk, PC Card, Trivial File Transfer Protocol (TFTP) file server, or PC before you install the NPE-G1 or NPE-G2, or the configuration will be lost and you will have to manually re-enter your configuration.

Cisco IOS looks to the NPE-G1 or NPE-G2 NVRAM for the startup running configuration, because the NPE-G1 or NPE-G2, by default, stores the running configuration, whether or not an I/O controller is installed with the NPE-G1 or NPE-G2.

The following sections provide instructions for copying the file to a Flash Disk, PC Card, or TFTP server, and for copying it manually using a terminal program on a PC:

Copying the Configuration File to a Flash Disk or PC Card

Copying the Configuration File to a TFTP Server

Copying the Configuration File Using a PC

Copying the Configuration File to a Flash Disk or PC Card

Use the following instructions for copying the router configuration file to a Flash Disk or PC Card.


Caution If the NPE-G1 or NPE-G2 will be installed in a router with either a C7200-I/O-GE/E or C7200-I/O-2FE/E I/O controller, copy your running configuration to a Flash Disk, not a PC Card. PC Cards are not supported on these I/O controllers when an NPE-G1 or NPE-G2 is present. If you copy the running configuration to a PC Card with these I/O controllers present, you will not be able to retrieve the running configuration after the NPE-G1 or NPE-G2 is installed.


Step 1 Insert the Flash Disk or PC Card into I/O controller PC Card slot 0. If slot 0 is full, use slot 1. If you need to format the Flash Disk, go to Step 2. If the Flash Disk is already formatted, go to Step 3.

Step 2 Use the format disk0: command to format a Flash Disk in slot 0. Use the format disk1: command to format a Flash Disk in slot 1. If you are using a PC card, use slot0 or slot1 as part of the command.

System# format disk0:
Format operation may take a while. Contineu: [confirm]
Format operation will destroy all data in `disk0:'. Continue? [confirm]
Format :Drive communication and 1st Sector Write OK...
Writing Monlib sectors 
..........................................................................................
Monlib write complete
Format:All system sectors written. OK...
Format:Total sectors in formatted partitioin:81760
Format:Total bytes in formatted partition:49861120
Format:Operation completed successfully.

Format of disk0:complete

The Flash Disk is now formatted and ready to use in the system on which you formatted it.

Step 3 Make sure you are at the privileged level of the EXEC command interpreter (check the system prompt for a pound sign [#]). If the system prompt does not have a pound sign (#), enter enable, and then your password.

Step 4 Enter the show running-config command to display the router's running configuration. Ensure that the configuration information is complete and correct. If it is not, use the configure command to add or modify the existing configuration. Then enter the copy running-config command. If you have a Flash Disk 0 or 1, use disk0 or disk1 as part of the command. If you are using a PC Card, use slot0 or slot1 as part of the command.

Step 5 To copy the running configuration file to the Flash Disk or PC Card, enter the copy running-config disk0: filename or copy running-config slot0: filename command:

System# copy running-config disk0: filename


You have finished copying the running configuration file to the Flash Disk or PC Card.

Go to the "Removing the Network Processing Engine" section for instructions on removing the current network processing engine or network services engine and replacing it with the NPE-G1 or NPE-G2.

Copying the Configuration File to a TFTP Server

Before copying the router configuration file to a TFTP file server, check the following items:

A console terminal is connected to the console port on the I/O controller or a Telnet session is established to the router.

The router is connected to a network supporting a file server (remote host).

The remote host supports the TFTP application.

You have the name or address of the remote host.

Complete the following steps to copy the router's configuration file to a remote host:


Step 1 Make sure you are at the privileged level of the EXEC command interpreter (check the system prompt for a pound sign [#]). If the system prompt does not have a pound sign (#), enter enable, and then your password.

Step 2 Use the ping command to check the connection between the router and the remote host.

Step 3 Enter the show running-config command to display the router's running configuration. Ensure that the configuration information is complete and correct. If it is not, use the configure command to add or modify the existing configuration. Then enter the copy running-config startup-config command to save the retrieved configuration in NVRAM. NVRAM uses lithium batteries to maintain its contents when disconnected from power.


Note Refer to the appropriate software documentation listed in the "Related Documentation" section on page iii for descriptions of the configuration options available for the system and individual interfaces, and for specific configuration instructions.


Step 4 Enter the copy startup-config tftp command. The EXEC command interpreter prompts you for the name or IP address of the remote host that is to receive the configuration file. (The prompt might include the name or address of a default file server.)

Router# copy startup-config tftp
Remote host []? 

Step 5 Enter the name or IP address of the remote host. In the following example, the name of the remote host is servername:

Router# copy startup-config tftp
Remote host []? servername
Translating "servername"...domain server (10.1.1.1) [OK]

Step 6 The EXEC command interpreter prompts you for the name of the file that will contain the configuration. By default, the system appends -confg to the router's name to create the new filename. Press Return to accept the default filename, or enter a different name for the file before pressing Return. In the following example, the default is accepted:

Name of configuration file to write [Router-confg]?
Write file Router-confg on host 10.1.1.1? [confirm]
Writing Router-confg..... 

Step 7 Before the router executes the copy process, it displays the instructions you entered for confirmation. If the instructions are not correct, enter n (no), and then press Return to stop the process. To accept the instructions, press Return, or y and then press Return; the system begins the copy process. In the following example, the default is accepted:

Write file Router-confg on host 10.1.1.1? [confirm]
Writing Router-confg: !!!! [ok]

While the router copies the configuration to the remote host, it displays a series of exclamation points (! ! !) or periods (. . .). The !!!! and [ok] indicate that the operation is successful. A display of . . . [timed out] or [failed] indicates a failure, which would probably be because of a network fault or the lack of a writable, readable file on the remote file server.

Step 8 Check the result of the copy process.

If the display indicates that the process was successful (with the series of exclamation points [! ! !] and [ok]), the copy process is complete. The configuration file is safely stored in the temporary file on the remote file server.

If the display indicates that the process failed (with the series of periods [. . .] as shown in the following example), your configuration was not saved:

Writing Router-confg ..... 

Step 9 If your configuration was not saved, repeat the preceding steps, or select a different remote file server and repeat the preceding steps. If you are unable to copy the configuration to a remote host successfully, contact your network administrator or see the "Obtaining Documentation and Submitting a Service Request" section on page iv for instructions on contacting technical assistance.


This completes the procedure for copying the configuration file to a TFTP server. Proceed to "Removing the Network Processing Engine" section.

Copying the Configuration File Using a PC

Complete the following steps to copy the router's configuration file to a text file on a PC connected to the router's console port.


Step 1 Connect a serial port on the PC to the router's console port. Start a terminal program on the PC and configure it for the same baud rate, parity, and stop-bits that the console port is using.

Step 2 Turn on the terminal program's capture buffer so that it will save all output to a text file.

Step 3 Enter the show startup-config command in privileged EXEC mode to display the router's startup configuration.


Note Refer to the appropriate software documentation listed in the "Related Documentation" section on page iii for descriptions of the configuration options available for the system and individual interfaces, and for specific configuration instructions.


Step 4 When the router has completed displaying the configuration, turn off the terminal program's capture buffer and save the configuration file to the disk on the PC.

Step 5 (Optional) Use a text editor on the PC to modify the configuration, as needed.


This completes the procedure for copying the configuration file to a PC. Proceed to "Removing the Network Processing Engine" section.

Removing the Network Processing Engine

Before you begin any removal or installation procedure, read Chapter 8, "Preparation for Installation." To install the NPE-G1 or NPE-G2, follow the instructions in this chapter for removal of an existing network processing engine or network services engine and installation of the NPE-G1 or NPE-G2.


Note If you are removing the I/O controller, and do not plan to replace it, you must install an I/O controller blank panel (Cisco Product Number IO-CONTROLR-BLANK=) in the I/O controller slot. See the Input/Output Controller Replacement Instructions for information on removing an I/O controller and installing an I/O controller blank panel.

If you are installing a Port Adapter Jacket Card, see the Port Adapter Jacket Card Installation Guide for installation information.


Ensuring Easy Access to the Router

If your Cisco 7200 VXR router or Cisco uBR7200 series router is installed in a standard 19-inch, 4-post or telco-type rack, cables from other equipment in the rack might obstruct access to the rear of the router. Also, rack power strips or other permanent fixtures may obstruct access to the router. Review the following guidelines to ensure easy access to the rear of the router when it is installed in a rack. This is particularly important because the NPE-G1 and NPE-G2 have interfaces that require cabling on the rear of the router.

If the router is not installed in a rack, or if you already have clear access to the rear of the router, proceed to the "Powering Down the Router and Disconnecting Input Power" section.

Use the following guidelines to ensure easy access to the rear of the router when it is installed in a rack:

Ensure that you have at least 3 to 4 feet (0.91 to 1.22 meters) of working space at the rear of the router.

If cables from other equipment in the rack fall in front of the rear end of the router, carefully gather the cables (using care not to strain or stress them) and use cable ties to anchor them away from the rear of the router.

If access to the rear of the router is partially blocked by a power strip or some other permanent rack fixture, detach the router from the rack and carefully slide it forward until there is enough clearance to remove the power supply, the network processing engine, and the subchassis from the router.


Caution Make sure that at least one other person is available to support the front of the router as you slide it out from the rack and, if necessary, to continue to support it while you remove and insert the power supply, network processing engine, or subchassis.

Powering Down the Router and Disconnecting Input Power

Complete the steps in the following sections to power down the router and disconnect input power.


Warning This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power cords before servicing. Statement 83


Powering Down the Router

To power down a Cisco 7200 VXR router or Cisco uBR7200 series router, complete the following steps:


Note Before powering down the router, use the copy running-config startup-config command to save the router's running configuration to a Flash Disk, PC Card, TFTP server, or PC. If you do not, you will have to manually re-enter the configuration after you install the NPE-G1 or NPE-G2 and power on the router. See the "Copying the Configuration File" section.



Step 1 Facing the rear of the router, place the power switch on the power supply in the off (O) position. Repeat this action if a second power supply is installed in the router.


Note When powering off the router, wait a minimum of 30 seconds before powering it on again.


Step 2 Observe the following items:

The green OK LED on the power supply turns off.

The fans stop operating.

The LEDs on the I/O controller turn off.

The LEDs on the port adapters turn off.



Caution When the power switch on a Cisco uBR7200 series power supply is turned to the off (O) position, the power supply enters a reset cycle for 90 seconds. Wait at least 90 seconds before turning the power switch back to the on (|) position. If you do not wait the full 90 seconds, the power supply does not restart.

This completes the procedure for powering down the router. The following sections provide instructions on disconnecting power from the Cisco 7200 VXR routers and Cisco uBR7200 series routers:

Note The Cisco uBR7225VXR router power supply does not have a cable retention-clip.



Disconnecting DC-Input Power from a Cisco 7200 VXR Router

To disconnect DC-input power from a Cisco 7200 VXR router, complete the following steps.


Warning Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. Statement 332



Warning When you install the unit, the ground connection must always be made first and disconnected last. Statement 42



Step 1 At the rear of the router, check that the power switch on the power supply is in the off (O) position. (For the Cisco 7200 VXR routers, see Figure 7-3.)

Step 2 Ensure that no current is running through the -V and +V leads. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off position, and tape the switch handle of the circuit breaker in the off position.

Step 3 Disconnect the -V and +V leads. You can leave the ground cable connected.
For a Cisco 7200 VXR router, remove the cable tie that secures the -V, +V, and ground leads to the power supply faceplate. Save the cable tie.


Note The cable tie that accompanied your Cisco 7200 VXR router DC-input power supply can be removed and replaced on the power supply without the use of a tool. If you secured the DC-input power supply leads to the power supply faceplate using a different type of cable tie, use a wire stripper to cut that cable tie from the power supply.

Note The weight of installed power supplies in your Cisco 7200 VXR or Cisco uBR7246VXR router might make it difficult to remove the network processing engine. If you have difficulty, first remove the power supplies from the chassis, and then remove the network processing engine. See the "Removing and Replacing an AC-Input or DC-Input Power Supply" section on page 10-14 for information on removing and replacing an installed power supply.



Note If you have difficulty installing a network processing engine or I/O controller in the lowest slot of a Cisco 7200 VXR router that is rack-mounted, remove the port adapters, network processing engine and I/O controller from the chassis and reinstall them. Install the network processing engine and I/O controller in the lowest slots first, then populate the slots above them, in a bottom-to-top order.



Step 1 Power down the router and disconnect the input power cable. (See the "Powering Down the Router and Disconnecting Input Power" section.)

Step 2 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.

Step 3 Using a number 2 Phillips or a 3/16-inch flat-blade screwdriver, loosen the two captive installation screws on the faceplate of the network processing engine. (See Figure 7-6.)

If the router is not installed in a standard 19-inch, 4-post or telco-type rack, skip to Step 7. If the router is installed in a rack, determine if any permanent rack fixtures, such as a power strip, are obstructing access to the rear of the router. If a rack fixture is obstructing access to the router, proceed with Step 4.

Step 4 Using a 3/16-inch flat-blade screwdriver, loosen the screws that secure the router to the front mounting strips of the rack.

Step 5 Position at least one person in front of the rack to support the front underside of the router.

Step 6 From the rear of the rack, carefully push the front of the router out of the rack until there is enough clearance to remove the network processing engine.

Step 7 Grasp the network processing engine handle and carefully pull the network processing engine from its chassis slot.


Caution Handle the network processing engine by the carrier edges and handle only; never touch the printed circuit board components or connector pins.

Step 8 Place the NPE on an antistatic surface with its printed circuit board components facing upward, or in a static shielding bag. If you are returning the network processing engine to the factory, immediately place it in a static shielding bag.


This completes the procedure for removing an installed NPE. For instructions on installing the NPE-G1 or NPE-G2, go to the "Installing the NPE-G1 or NPE-G2" section.

Reconnecting DC-Input Power to the Cisco 7200 VXR Router

To reconnect DC-input power to a Cisco 7200 VXR router, complete the following steps.


Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green and yellow are used for ground. Make certain that the lead color coding you choose for the DC-input power supply matches the lead color coding used at the DC power source.



Warning Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. Statement 322



Warning When installing the unit, the ground connection must always be made first and disconnected last. Statement 42



Step 1 At the rear of the router, check that the power switch on the power supply is in the off (O) position.

Step 2 Ensure that no current is running through the -V and +V leads. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off position, and tape the switch handle of the circuit breaker in the off position.

0.55 in. (14 mm)

   

Step 4 For the Cisco 7200 VXR routers, insert the stripped end of the ground lead all the way into the ground lead receptacle on the DC-input power supply and tighten the receptacle screw using a 3/16-inch flat-blade screwdriver.

Step 5 Insert the stripped end of the +V lead all the way into the +V lead receptacle and tighten the receptacle screw using the same 3/16-inch flat-blade screwdriver. Repeat this step for the -V lead.


Note Make sure that the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and repeat through Step 5.


Step 6 After tightening the receptacle screws for the ground, +V, and -V DC-input leads, secure the leads to the power supply faceplate.

Use the cable tie you saved earlier in this procedure to secure the three leads.


Note When securing the ground, +V, and -V DC-input leads to the power supply faceplate, leave a small service loop in the ground lead to ensure that it is the last lead to disconnect from the power supply if a great deal of strain is placed on all three leads. (See Figure 7-27.)


Step 7 Restore current to the -V and +V leads.


Note For the Cisco 7200 VXR routers:
- Each DC-input power supply operating at 24 VDC requires a minimum of 19A service.
- Each DC-input power supply operating at 48 VDC requires a minimum of 13A service.
- Each DC-input power supply operating at 60 VDC requires a minimum of 8A service.

This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker, 35A minimum 60 VDC, is used on all current-carrying conductors. Site wiring and circuit breakers need to be sized to accommodate the maximum values for safety reasons.


Step 8 Repeat Step 1 through Step 7 if a second power supply is installed.


This completes the steps for reconnecting DC-input power to a Cisco 7200 VXR router. Proceed to the "Powering Up the Router" section.

Reconnecting DC-Input Power to a Cisco uBR7246VXR Router

To reconnect DC-input power to a Cisco uBR7246VXR router, complete the following steps.


Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green and yellow are used for ground. Make certain that the lead color coding you choose for the DC-input power supply matches the lead color coding used at the DC power source.



Warning Before completing any of the following procedures, and to prevent short-circuit or shock hazards, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. Statement 322



Warning When installing the unit, the ground connection must always be made first and disconnected last. Statement 42



Step 1 At the rear of the router, check that the power switch on the power supply is in the off (O) position.

Step 2 Ensure that no current is running through the -V and +V leads. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off position, and tape the switch handle of the circuit breaker in the off position.

Step 3 SIf necessary, use a wire stripper to strip approximately 0.55 inch (14 mm) from the -V, +V, and ground leads.


Note The ground lead for the Cisco uBR7200 series DC-input power supply consists of a two-hole grounding lug that connects to an M5 grounding receptacle; you do not need to strip this ground lead.


Figure 7-30 Stripping the DC-Input Lines

0.55 in. (14 mm)

   

Step 4 Connect the two-hole grounding lug on the grounding lead to the M5 grounding receptacles with the M5 nuts. Tighten the nuts using an 8-mm wrench or nut driver (or adjustable wrench). (See Figure 7-31.)

Step 5 Insert the stripped end of the +V lead all the way into the +V lead receptacle and tighten the receptacle screw using the 3/16-inch flat-blade screwdriver. Repeat this step for the -V lead.


Note Make sure that the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and repeat through Step 5.


Step 6 After tightening the receptacle screw or nuts for the ground, +V, and -V DC-input leads, secure the leads to the power supply faceplate.

Step 7 Run the +V and -V leads between the two strain-relief studs on the power supply faceplate.


Note A service loop is not required in the lead attached to the grounding lug because this lead is separate from the +V and -V leads and is secured by two M5 nuts to the M5 receptacles.


Step 8 Replace the strain-relief cover over the +V and -V leads and secure the cover to the strain-relief studs with the two M4 nuts using the 7-mm wrench or nut driver (or adjustable wrench).

Note For the Cisco uBR7200 series routers, each DC-input power supply rating is 14A, 700 volt ampere (VA).

This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker, 35A minimum 60 VDC, is used on all current-carrying conductors. Site wiring and circuit breakers need to be sized to accommodate the maximum values for safety reasons.


Step 10 Repeat Step 1 through Step 9 if a second power supply is installed.


This completes the steps for reconnecting DC-input power to a Cisco uBR7246VXR router. Proceed to the following section, "Powering Up the Router."

Powering Up the Router

To power up a Cisco 7200 VXR router, Cisco uBR7246VXR router, or Cisco uBR7225VXR router that has an installed power supply, complete the following steps:


Step 1 Check for the following:

Each port adapter is inserted in its slot, and its respective port adapter lever is in the locked position.

The network processing engine and the I/O controller or I/O controller blank panel are inserted in their respective slots, and the captive installation screws are tightened.

All network interface cables are connected to the port adapters or I/O controller or NPE-G1 or NPE-G2 interfaces.

Each cable interface line card is inserted in its slot, and its respective captive installation screws are tightened (Cisco uBR7246VXR router only).

(Optional) A CompactFlash Disk is installed in the CompactFlash Disk slot in the NPE-G1 or NPE-G2. If you also have an I/O controller installed, you can optionally install a PC Card or Flash Disk in one of the I/O controller's PC Card slots.


Note A Flash Disk can be installed in either slot 0 or slot 1 of the I/O controller. A CompactFlash Disk can be installed only in the CompactFlash Disk slot in the NPE-G1 or NPE-G2.


(Optional) A USB Flash memory module or USB eToken Pro key is inserted into a USB port on the NPE-G2.

Each AC-input power cable is connected and secured with the cable-retention clip, except for uBR7224VXR routers(AC-input power supplies only).

For a Cisco 7200 VXR router, each DC lead is connected and secured to the power supply faceplate with a cable tie.

For a Cisco uBR7246VXR router, each DC lead is connected with M4 nuts for the grounding receptacle and the strain-relief cover over the +V and -V leads (DC-input power supplies only).

Each DC lead is connected and secured to the power source (DC-input power supplies only).

Ensure that the tape (that you applied earlier) is removed from the circuit breaker switch handle, and power is restored by moving the circuit breaker handle to the on (|) position (DC-input power supplies only).

The console terminal is turned on.


Caution When the power switch on a Cisco uBR7200 series power supply is turned to the off (O) position, the power supply enters a reset cycle for 90 seconds. Wait at least 90 seconds before turning the power switch back to the on (|) position. If you do not wait the full 90 seconds, the power supply does not restart.

Step 2 At the rear of the router, place the power switch on the power supply in the on (|) position. Repeat this step if a second power supply is installed in the router. The green OK LED on the power supply turns on.


Note When powering on the router, wait a minimum of 30 seconds before powering it off again.


Step 3 Listen for the fans; you should immediately hear them operating.

Step 4 During the boot process, observe the system LEDs. The LEDs on most of the port adapters go on and off in an irregular sequence. Some may go on, go off, and go on again for a short time. On the NPE-G1 or NPE-G2 and the I/O controller, the POWER OK LED goes on immediately.

Step 5 Observe the initialization process. When the system boot is complete (a few seconds), the NPE-G1 or NPE-G2 begins to initialize the port adapters and the I/O controller. During this initialization, the LEDs on each port adapter behave differently (most flash on and off). The enabled LED on each port adapter and Cisco uBR7200 series cable interface line card goes on when initialization is completed, and the console screen displays a script and system banner similar to the following:

This completes the procedures for connecting input power and powering up the router. This also completes the procedure for installing the NPE-G1 or NPE-G2 in a Cisco 7200 VXR router, Cisco uBR7246VXR router, or Cisco uBR7225VXR.

Enabling the Second Processor on the NPE-G1

The Cisco 7200VXR NPE-G1 includes a dual-CPU-core BCM1250 processor. All Cisco IOS images for the Cisco 7200VXR NPE-G1 use CPU-core 0. CPU-core 1 allows acceleration of specific feature sets via separately purchased special software. As of Cisco IOS Release 12.3(14)YM, multi-processor forwarding (MPF) accelerates the following broadband features: L2TP Access Concentrator (LAC), L2TP Network Server (LNS), and PPP Terminated Aggregation (PTA). Port adapters are not supported in the multi-processor forwarding (MPF) path on processor 1.

Only the following port adapters are supported in the punt path (Processor 0 processing Cisco IOS) on Cisco IOS Release 12.3(14)YM and later releases of Cisco IOS Release 12.3YM:

PA-A3-OC3 (SMI/SML/MM)

PA-A3-T3

PA-A3-E3

PA-A6-OC3 (SMI/SML/MM)

PA-A6-T3

PA-A6-E3

PA-FE-TX

PA-2FE-TX

PA-2FE-FX

You may have purchased the enabling software when you purchased a new chassis or you may have purchased the software as an upgrade.

If you are purchasing the software as an upgrade, you must:

Upgrade the ROMmon. (The minimum ROMmon version is 12.3-4r.T3.)

Install the enabling software.

Instructions for upgrading ROMmon are in the "Using the upgrade rom-monitor file Command" section.

The minimum software release for the Broadband L2TP Access Concentrator (LAC), L2TP Network Server (LNS), and PPP Terminated Aggregation (PTA) is Cisco IOS Release 12.3(14)YM.

Also see the MPF for Broadband LAC, LNS, and PTA document for minimum memory requirements and configuration information.


Note Before enabling the second processor, you must have IP routing turned on.


Processor 1 is enabled by default after you install the enabling software. To have all packets forwarded by processor 0, use the no ip mpf command. To enable processor 1, use the ip mpf command.


Save the running configuration to NVRAM. See the "Copying the Saved Configuration to NVRAM" 
section. If you do not save the configuration settings that you created in the router using configuration 
mode and the setup facility, your configuration will be lost the next time you reload the router.

Copying the Saved Configuration to NVRAM

After installing and cabling the NPE-G1 or NPE-G2 and powering on the router, copy the configuration file to the NVRAM on the NPE-G1 or NPE-G2, using one of the following procedures:

If you have kept the previous I/O controller installed in the router, use the procedure given in the "Copying the Saved Configuration File from a Flash Disk or PC Card" section to copy the saved configuration to the NVRAM on the NPE-G1 or NPE-G2.

If you have removed the previously installed I/O controller from the router, and you were able to copy the file to a CompactFlash Disk, use the procedure given in the "Copying the Saved Configuration File from the CompactFlash Disk" section to copy the saved configuration file to the NVRAM on the NPE-G1 or NPE-G2.

If you have removed the previously installed I/O controller from the router, and you have not been able to copy the file to a CompactFlash Disk, use the procedure given in the "Downloading the Saved Configuration from the TFTP Server" section to copy the saved configuration file to the NVRAM on the NPE-G1 or NPE-G2.

Copying the Saved Configuration File from a Flash Disk or PC Card

To copy the saved configuration file from the Flash Disk or PC Card, follow these steps:


Step 1 Make sure you are at the privileged level of the EXEC command interpreter (check the system prompt for a pound sign [#]). If the system prompt does not have a pound sign (#), enter enable, and then your password.

Step 2 Insert the Flash Disk or PC Card containing the saved configuration file into the first PC Card slot in the I/O controller.

Step 3 Enter the copy disk0: filename running or copy slot0: filename running command.

Router# copy disk0:filename running 
or

You have finished copying and writing the saved configuration file to NVRAM.

Copying the Saved Configuration File from the CompactFlash Disk

If you have been able to copy the configuration file to the CompactFlash Disk, use the following steps to copy the configuration to the NVRAM on the NPE-G1 or NPE-G2:


Step 1 Make sure you are at the privileged level of the EXEC command interpreter (check the system prompt for a pound sign [#]). If the system prompt does not have a pound sign (#), enter enable, and then your password.

Step 2 Insert the CompactFlash Disk containing the saved configuration file into the CompactFlash Disk slot on the NPE-G1 or NPE-G2.

Step 3 Enter the copy disk2: filename command.

Router# copy disk2:filename running 

Step 4 Enter the write command:

Router#: write 


You have finished copying and writing the saved configuration file to NVRAM.

Downloading the Saved Configuration from the TFTP Server

After you install the NPE-G1 or NPE-G2 in the router and verify a successful router boot, you must retrieve the router configuration from the TFTP server and copy it to NVRAM. Use the copy tftp running-config command to copy the saved configuration from the TFTP file server. The system prompts you for a hostname and address, the name of the configuration file stored on the host, and confirmation to reboot using the remote file.

After the NPE-G1 or NPE-G2 is installed, save the router configuration file to NVRAM (the default is the NPE-G1 or NPE-G2 NVRAM) using the copy system:running-config nvram:startup-config command as follows:

Router# copy system:running-config nvram:startup-config 

You will want to configure the NPE-G1or NPE-G2 interfaces after retrieving the router configuration and copying it to NVRAM.

Before retrieving the router configuration file from the TFTP server, check the following:

A console terminal is connected to the console port on the NPE-G1 or NPE-G2, or a Telnet session is established to the router.

The router is connected to a network supporting a file server (remote host).

The remote host supports the TFTP application.

You have the name or address of the remote host.

Before configuring the new interfaces on the NPE-G1 or NPE-G2, be prepared with the following information:

Protocols and encapsulations you plan to use on the new interface

Protocol-specific information, such as IP addresses if you will configure the interface for IP routing

For complete descriptions of interface commands and the configuration options available for Cisco 7200 VXR-related interfaces, refer to the documentation resources listed in the "Related Documentation" section on page iii.

To retrieve the saved router configuration from the remote host, complete the following steps:


Step 1 Make sure you are at the privileged level of the EXEC command interpreter (check the system prompt for a pound sign [#]). If the system prompt does not have a pound sign (#), enter enable, and then your password.


Note Until you retrieve the saved configuration, the router runs from the default configuration in NVRAM. Therefore, any passwords that were previously configured on the system are not valid until you retrieve the configuration.


Step 2 Use the ping command to check the connection between the router and the remote host (the remote file server to which you copied the configuration file).

Step 3 At the system prompt, enter the copy tftp running-config command and press Return to enter configuration mode. Specify that you will configure the system from a network device (instead of from the console terminal, which is the default).

Router# copy tftp running-config

Step 4 The system prompts you to select a host or network configuration file. The default is host; press Return to accept the default.

Host or network configuration file [host]?

Step 5 The system prompts you for the IP address of the host. Enter the IP address or name of the remote host.

IP address of remote host [255.255.255.255]? 10.1.1.1

Step 6 The system prompts you for the name of the configuration file. When the system copies the file to the server, the default is to use the name of the router with the suffix -confg (router-confg in the following example). If you specified a different filename when you copied the configuration, enter that filename; otherwise, press Return to accept the default.

Name of configuration file [router-confg]?

Step 7 Before the system reboots with the new configuration, it displays the instructions you entered for confirmation. If the instructions are not correct, enter n (no), and then press Return to cancel the process. To accept the instructions, press Return, or y and then Return.

Configure using router-confg from 10.1.1.1? [confirm]
Booting router-confg from 10.1.1.1: ! ! [OK - 874/16000 bytes]

While the router retrieves and boots from the configuration on the remote host, the console display indicates whether or not the operation was successful. A series of exclamation points (!!!!) and [OK] (as shown in the preceding example) indicates that the operation was successful. A series of periods (. . .) and [timed out] or [failed] indicates a failure (which would probably be due to a network fault or an incorrect server name, address, or filename). The following is an example of a failed attempt to boot from a remote server:

Booting Router-confg ..... [timed out]

If the display indicates that the process was successful, proceed to the next step.

If the display indicates that the process failed, verify the name or address of the remote server and the filename, and repeat the preceding steps. If you are unable to retrieve the configuration, contact your network administrator or see the "Obtaining Documentation and Submitting a Service Request" section on page iv for instructions on contacting Cisco technical assistance.

Step 8 Enter the show running-config command to display the currently running configuration on the terminal. Review the display and ensure that the configuration information is complete and correct. If it is not, verify the filename and repeat the preceding steps to retrieve the correct file, or use the configure command to add or modify the existing configuration. (Refer to the appropriate software documentation for descriptions of the configuration options available for the system and individual interfaces and specific configuration instructions.)

Step 9 When you have verified that the currently running configuration is correct, enter the copy running-config startup-config command to save the retrieved configuration in NVRAM. Otherwise, the new configuration will be lost when you restart the system.


This completes the procedure for downloading the saved router configuration from the remote host. Proceed to the "Configuring the Native Gigabit Ethernet Interfaces" section.

Auxiliary and Console Port Information

If the NPE-G1 or NPE-G2 and an I/O controller are both installed in the same system, the console and auxiliary ports on the I/O controller are used and the console and auxiliary ports on the NPE-G1 or NPE-G2 are disabled by Cisco IOS.

Both the NPE-G1 or NPE-G2 and the I/O controller console ports are available from the ROM monitor (ROMmon); however, once the system has completed loading the Cisco IOS image, the console port on the NPE-G1 or NPE-G2 is disabled if an I/O controller is also installed in the router.

If the NPE-G1 or NPE-G2 is used without an I/O controller, the console and auxiliary ports on the NPE-G1 or NPE-G2 are available both during and after loading the Cisco IOS image.

Configuring an Auxiliary Port to Receive Console Port Messages

If you choose to have console port messages routed to the auxiliary port, use the Cisco IOS command terminal monitor on the auxiliary port on which you desire to receive console messages.

Router# terminal monitor

Configuring the Native Gigabit Ethernet Interfaces

The NPE-G1 and NPE-G2 report both the RJ-45 and GBIC or SFP GE interface ports as GigabitEthernet 0/1, GigabitEthernet 0/2, and GigabitEthernet 0/3. Each interface has two ports with two different media types, GBIC or SFP, or RJ-45 (default). You can use only one port for each interface, and before configuring either port type, you must first use the media-type interface command to select the media type, GBIC (gbic) for NPE-G1 or SFP (sfp) for NPE-G2, or RJ-45 (rj45) port.


Note The Gigabit Ethernet interfaces on the NPE-G1 and NPE-G2 do not support the Inter-Switch Link (ISL) VLAN encapsulation protocol. We recommend that customers use the IEEE 802.1Q VLAN encapsulation protocol as an alternative. Where an application requires the use of ISL, this can be provided by the Fast Ethernet or Gigabit Ethernet port adapters or I/O controllers.



Note The RJ-45 port is the default media.


Changing the Media Type of the Native Gigabit Ethernet GBIC, SFP,
or RJ-45 Ports

To be able to use a particular media port, use Cisco IOS to select the media type. This is done by using the media-type interface command:

media-type { gbic | sfp | rj45 }

Example:


interface GigabitEthernet 0/1
	media-type rj45
end

Configuring the Interface Transmission and Speed Modes


Step 1 After changing the media type, configure the speed and transmission modes to appropriately match the new interface characteristics. Changing the speed and duplex of an NPE-G1 or NPE-G2 Gigabit Ethernet interface is done using the speed and duplex interface commands.


Note These commands are only applicable when using the RJ-45 media.


speed { 10 | 100 | 1000 | auto } 
duplex { full | half | auto }

The following speed/duplex settings are supported:

Media Type          Speed                    Duplex 
------------------------------------------------------- 
RJ45            10, 100, 1000, auto      full, half, auto
GBIC(1)         1000, auto(2)            full, half, auto
-------------------------------------------------------

a. If you are using the no negotiation auto command, the speed and duplex should be set to a value other than auto for correct operation.

b. The only available speed in the no autonegotiation mode is 1000 Mbps; there is no difference whether 1000 or auto is selected.

When using the GBIC media, there is also the additional negotiation auto command that is used to enable the IEEE 802.1z Gigabit Ethernet (1000 Mbps) autonegotiation protocol.

Step 2 To turn the autonegotiation feature off (it is on by default), issue the interface command no negotiation auto. This is useful for connecting to other Gigabit Ethernet equipment that does not support 802.1z autonegotiation.


Note The autonegotiation feature is not supported when using the rj-45 media type and will be ignored if implementation is attempted.


If you change from the GBIC or SFP to the rj-45 media type, you must set speed and duplex after you have executed the media-type command to ensure the interface will operate in the correct mode.

The media-type GBIC or media-type SFP mode will always default to 1000 Mbps. Both full-duplex and half-duplex operations are supported in this mode.


Sample Configuration for the Gigabit Ethernet Interfaces

The following shows a typical configuration for the three Gigabit Ethernet interfaces on the NPE-G1. The same configuration would be typical for the NPE-G2 also, although the second interface would be configured for the SFP media type. In this example, the first interface is configured for the GBIC media type, the second interface is configured for the RJ-45 media type, and the third interface is not used.

interface GigabitEthernet0/1
 ip address 10.198.75.35 255.255.255.240
 load-interval 30
 no keepalive
 duplex full
 speed 1000
 media-type gbic
 no negotiation auto
 no cdp enable
 no shutdown 
!
interface GigabitEthernet0/2
 ip address 10.179.16.2 255.255.255.240
 duplex auto
 speed auto 
 media-type rj45
 no cdp enable
 no shutdown 
!
interface GigabitEthernet0/3
 no ip address
 shutdown
 duplex auto
 speed auto
 media-type rj45
 no negotiation auto
 no cdp enable

Note At the very minimum, an interface must be configured with the ip address, media-type, and speed commands before it can be enabled using the no shutdown command. Other interface commands might be needed, depending on the nature of the connected network.


Debugging

Cisco IOS provides two commands to provide information on your interfaces: show interface GigabitEthernet 0/X (where X is 1, 2, or 3) and show controllers GigabitEthernet 0/0.

The output of the show interface command is useful for determining the current operating mode of the interface (speed/duplex/media-type) and the current interface statistics.

The output of the show controllers command displays more information specific to the I/O controller interface. For example, it shows the detected link status, speed, and duplex, and also determines the current status of autonegotiation and the link partners' abilities (if it is an autonegotiation-capable interface).

The show controllers command also displays the current operating state of the driver and the Ethernet controller hardware. The show controllers command is a very powerful debugging aid, especially for Cisco engineers should you need help in debugging a problem. If you have any problems with your Gigabit Ethernet interfaces, you will need to provide the show controllers command output to Cisco for analysis.

Resetting the Interface

Should you have a problem with your interface and wish to try and reset it, use the command:

clear interface GigabitEthernet 0/X    (where X is 1, 2, or 3)

Clearing Counters

Interface counters may be cleared (reset) by using the command:

clear counters GigabitEthernet 0/X    (where X is 1, 2, or 3)

This will not reset the interface.

Using show Commands to Check the Installation

Use show commands to identify the hardware installed in your router, to verify the operation status, to view interface configuration settings, and to troubleshoot your router configuration. The interfaces on the NPE-G1 and NPE-G2 are identified by their chassis slot number and interface port number (slot/port). The interfaces on your I/O controller are also identified by chassis slot number and interface port number (slot/port). The chassis slot number for the I/O controller is always slot 0. Table 7-1 lists the NPE-G1, NPE-G2, the I/O controller models, their corresponding interfaces, and the interface addressing syntax for each interface.

2 The Product Number C7200-I/O-FE does not specify MII because both an MII and an RJ-45 receptacle are included.

3 The I/O controller with the Product Number C7200-I/O-FE-MII has a single MII Fast Ethernet receptacle only. Although still supported by Cisco, this I/O controller with a single MII receptacle is no longer an orderable product as of May 1998.


The remainder of this section provides examples of show commands that pertain to the NPE-G1 and NPE-G2. The output from the show commands is from the NPE-G1 or the NPE-G2.

To determine the hardware configuration of your NPE-G1 or NPE-G2, use the show version command.

The following example shows an NPE-G2 installed in a Cisco 7206VXR router:

Upgrading the Cisco IOS Image and the Boot Helper (Boot Loader) Image

Should you ever upgrade the Cisco IOS image on your Cisco 7200 VXR router with an NPE-G1 or NPE-G2, you need to ensure that you also upgrade your boot helper (boot loader) image.

The boot helper (boot loader) image resides in flash memory on the NPE-G1 and NPE-G2 and contains a subset of the Cisco IOS software. This image is used to boot your router from the network or to load Cisco IOS images onto the router. This image is also used if the system cannot find a valid system image.

Your boot helper (boot loader) image should correspond to the Cisco IOS release that is running on your router.

The NPE-G1 requires the c7200-kboot boot helper image.

The NPE-G2 requires the c7200p-kboot-mz helper image.

The Cisco uBR7200-NPE-G1 requires the ubr7200-kboot-mz boot helper image.

The Cisco uBR7200-NPE-G2 requires the ubr7200p-kboot-mz boot helper image.

To upgrade your boot helper (boot loader) image, obtain the most current boot helper image through Cisco.com and copy the new boot helper image to flash memory on your router. For information on how to access Cisco.com, see the "Obtaining Documentation and Submitting a Service Request" section on page -iv. Follow the Software Center link under Service and Support. You need to get a login code from a Cisco representative to retrieve files from the Software Center.

To obtain a boot helper (boot loader) image from Cisco.com and upgrade your boot flash memory, do the following:


Step 1 Download the boot helper (boot loader) image from Cisco.com to a Trivial File Transfer Protocol (TFTP) server.

Step 2 Reformat the flash memory on your router as follows:

router# format bootflash:
Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "bootflash:".  Continue? [confirm]
Formatting sector ...   
Format of bootflash:complete

Note Reformatting flash memory erases the current flash memory contents.


Step 3 Copy the boot helper image from the TFTP server to flash memory as follows:

router# copy tftp bootflash:
Address or name of remote host []? biff
Source filename []? c7200-boot-mz.120-5.S
Destination filename [c7200-boot-mz.120-5.S]? 
Accessing tftp://biff/c7200-boot-mz.120-5.S...

This completes the procedure for upgrading your boot helper (boot loader) image. For more detailed instructions on loading and maintaining system images and microcode, including boot helper images, refer to the Configuration Fundamentals Configuration Guide, which is available on Cisco.com.

Upgrading ROMmon on the NPE-G1 or NPE-G2

Upgrading the rewriteable ROM monitor (ROMmon) allows you to download a new ROMmon image instead of having to replace hardware (NPE-G1 or NPE-G2) to get a new image.


Note ROMmon can be upgraded on the NPE-G1 or NPE-G2, but cannot be upgraded on any other network processor engine for the Cisco 7200 series routers.


There are two ROMmon images: one ReadOnly image (the original image that shipped with your system) that is always available if you have the following:

NPE-G1 hardware EPROM version 4.0 with NPE-G1 ROMmon version 12.3(4r)T1 or later

NPE-G2 hardware

You can choose to configure the system to point to the second ROMmon image, the upgradeable ROMmon image. At bootup, the system starts with the ReadOnly image and then, if configured, jumps to the upgradeable image. If the upgradeable ROMmon image fails to boot, the router will mark this ROMmon image as invalid and revert to the ReadOnly image.

The first time a new ROMmon image is executed, you must allow the system to boot ROMmon before doing any additional resets or power cycling. If the ROMmon-executing process is interrupted, the stem interprets this as a bootup failure of the new ROMmon image. The router reverts to the ReadOnly image.


Note The ROMmon upgrade image is marked as invalid if it fails to boot. Do not reset the router when it is performing an initial bootup.


Using the show rom-monitor Command and ROMmon CLI showmon Commands

Use the show rom-monitor command if you are in Cisco IOS, or the ROMmon CLI showmon command if you are in ROMmon, to determine which ROMmon images are available. See the following examples for information shown in the output of the show rom-monitor or ROMmon CLI showmon commands:

If you are in Cisco IOS, use the show rom-monitor command:

Changing Preferences to Choose the Other ROMmon Image

To use the other ROMmon image, use one of the following commands to make the change depending on whether you are in Cisco IOS or in ROMmon:

In Cisco IOS, use the upgrade rom-monitor preference command to change to the other ROMmon image:

upgrade rom-monitor preference [readonly | upgrade]


Example:

Router: upgrade rom-monitor preference readonly
You are about to mark ReadOnly region of ROMMON for the highest boot preference.
Proceed? [confirm]
Done! Router must be reloaded for this to take effect.

In ROMmon, use the ROMmon CLI rommon-pref command to change to the other ROMmon image:

rommon-pref [readonly | upgrade]


Example:

rommon 2 > rommon-pref readonly

Troubleshooting the Upgrade

This section contains sample error messages that appear if an upgrade fails, or if an upgrade is successful, but the upgrade image is corrupted.

Upgrading FPGA on the NPE-G2

A field-programmable gate array (FPGA) device exists on the NPE-G2. FPGA devices do not exist on other Cisco 7200 series routers network processing engines. FPGA devices are a type of field-programmable device (FPD) that support separate software upgrades. Whenever a Cisco image is released that supports the FPD feature, a companion FPD image package is also released for that
Cisco IOS software release. The FPD image package is available from Cisco.com and is accessible from the Cisco Software Center page where you go to download your Cisco IOS software image.


Note For Cisco IOS Release 12.4(4)XD, only a manual FPD upgrade of the NPE-G2 is supported.


For FPGA upgrade information and procedures, see the Field-Programmable Device Upgrades document at:
