pment.

This hardware upgrade has an impact on user traffic. The router is not available for user traffic during the upgrade, andtrafficcannot resume until the upgrade is complete.

Caution PRE1s and PRE3s cannot operate in

the same chassis.

• Allnew PRE3sare shippedwith ahelper image stored in boot flash memory, and without any configuration.

• Make sure you save your configuration information to a TFTP server before removing the old PRE from the chassis.

Caution You cannot save the configuration

information to a PRE2 media card to use in a PRE3. When you remove the former PRE from the chassis local configuration information is lost.

Saving the Startup and Running Configuration Information

Use the following procedure to save the configuration information to a TFTP server.

Step 1 Connect the console to the primary PRE. Step 2 Save the startup configuration and

running configuration to the TFTP server.

Use the following tools to perform the upgrade:

• Phillips-head screwdriver

• ESD grounding wrist strap

Caution Always wear a grounding wrist strap

to preventESD damage to the module.

Removing the PRE Module

Use thefollowing procedure toremove the existing PRE module from the chassis.

Step 1 Attach the ESD wrist strap to the chassis

to ensure you are properly grounded.

Step 2 Power off the router.

Caution Although PRE modules can be

hot-swapped, removing a module terminates all traffic. We recommend that you power off the router to ensure a successful installation.

Step 3 Disconnect all cables from the PRE. Step 4 Loosen thetop and bottom captivescrews. Step 5 Pivot both ejector leverssimultaneously to

disengage the module from the backplane.

Step 6 Remove the PRE from the chassis and

place it on an antistatic surface or in an antistatic bag.

Step 7 If you are replacing a redundant PRE,

repeat steps 3 though 6.

Use the following procedure module.

Caution To ensure prope

• If you booted the full image, restore the startup and running configuration information, and set the variable for the new image. The upgrade is now complete.

• If you booted from the helper image:

–

Download the full image.

–

Restore the startup and running configuration information.

–

32682

Set the boot variable to the new image.

–

Reload the router.

The upgrade is now complete.

If this sequence does not occur, check the following:

• Check to see if the LEDs on the other modules are operating. If not, check for a problem in the power subsystem.

• Remove the PRE3 and check for bent or broken pins on the backplane connectors.

• Verify the status of the PRE3s internal Ethernet interface (ethernet 0/0/0). If this interface is down it could indicate that the PRE3 is not fully seated in the slot, or that a hardware failure occurred.

Note Do not confuse the PRE3 internal

Ethernet interface (ethernet 0/0/0) with the module’s external Fast Ethernet interface (fastethernet 0/0/0) which is used for network management or remote access.

Installing a Redundant PRE3

Use the following procedure to install a redundant PRE3.

Step 1 Repeat Step 1 through Step 8 for slot B

(see Installing the PRE3 Module).

Step 2 Setthe configuration toboot the fullimage

and reload from the console ROMMON prompt.

2 Troubleshooting

The PRE3 displays the following sequence of events when booted:

• The FAIL LED lights briefly, followed by a flashing STATUS LED, and progress messages appear on the PRE3 display.

• IOS RUN appears after a successful boot.

• The STATUS LED remains on (green).

• Refer to Table 1 for LED and switch

descriptions.
