Cisco 10008 Router Performance Routing Engine 3 Installation
OL-8544-01
Upgrading Software
Prerequisites
For all of the software features supported by your current PRE2 (c10k2-p11-mz) image to function
correctly, they must be supported by the PRE3 image. Check with the Cisco Technical Assistance Center
(TAC) to verify the correct upgrade path before initiating the upgrade.
The upgrade should be performed by a qualified engineer. This person must be familiar with the Cisco
router console interface and be able to perform basic router operations, such as configuration loading
and router reload functions.
Caution Do not perform this upgrade if your current PRE2 software image supports new features not yet
supported by the PRE3 software image. Performing this upgrade will cause these features to fail.
Upgrade Considerations
• This is a service impacting hardware upgrade. The router will not be available for user traffic during
the upgrade, and traffic cannot resume until the upgrade is complete.
• All new PRE3s are shipped with an eboot image (c10k3-eboot-mz) stored in bootflash.
Procedure to Upgrade a PRE2 to a PRE3
Follow this procedure to upgrade a single PRE2 in a Cisco 10008 chassis that does not have a redundant,
standby PRE2.
Step 1 Connect a terminal to the active PRE2.
Step 2 Save the startup and running configuration to a location on a TFTP server.
Caution When the PRE2 is removed from the chassis, any local configuration will be lost. You must
save your configuration to a TFTP server.
Step 3 Power down the router. All the traffic on the router is stopped.
Note PRE2s can be hot-swapped. However, because removing a PRE2 stops all traffic, we recommend
that you power down the router to ensure a successful installation.
Step 4 Attach an antistatic strap to your wrist or ankle and to an ESD socket on the chassis, or to a bare metal
surface on the chassis or frame.
Step 5 Remove the PRE2 from the chassis using the procedure in the “Removing a PRE3” section on page 14 .
Step 6 Insert the PRE3 into slot 0A of the chassis by following the procedure in the “Installing a PRE3” section
on page 11 .
a. If you do not have a second, redundant PRE3 to install, a blank card must be used to fill the unused
slot 0B.
Note Although a PRE3 can be installed in slot 0B, we recommend that you install a single,
non-redundant PRE3 in slot 0A to ensure proper operation.
