Considerations Before Upgrading
This hardware upgrade has an impact on user
traffic. The router is not available for user traffic
during the upgrade, and traffic cannot resume until
the upgrade is complete.
Caution PRE1s and PRE3s cannot operate in
the same chassis.
•AllnewPRE3sareshippedwith a helper 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.
Tools
Use the following tools to perform the upgrade:
•Phillips-head screwdriver
•ESD grounding wrist strap
Caution Always wear a grounding wrist strap
to prevent ESD damage to the module.
Removing the PRE Module
Use the following procedure to remove 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 the top and bottom captive screws.
Step 5 Pivot both ejector levers simultaneously 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.

•If you need to access the TFTP server
to obtain the full image or the saved
configuration files, enter the
configuration dialog and enter the
information to access the TFTP server.
•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.
– Set the boot variable to the new
image.
– Reload the router.
The upgrade is now complete.
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 Settheconfiguration to bootthefullimage
and reload from the console ROMMON
prompt.
2Troubleshooting
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).
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.
•Refer to Table 1 for LED and switch
descriptions.
