Upgrading a PRE3 to a PRE4
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
supported by the PRE4 software image. Performing this upgrade will cause these features to fail.
Upgrade Considerations
Every new PRE4 is shipped with an eboot image (c10k4-eboot-mz) stored in bootflash.
This is a service impacting upgrade. The router is not available for user traffic during the upgrade, and
Note
traffic cannot resume until the upgrade is complete.
Procedure to Upgrade a PRE3 to a PRE4 Without Using ISU
To upgrade a PRE3 to a PRE4 without using ISU, follow these steps:
Connect a terminal to the active PRE3.
Step 1
Save the startup and running configuration to a location on a TFTP server.
Step 2
Caution

Power up the router. The router boots in read-only memory (ROM) monitor mode.
Step 8
From the console in ROM monitor mode, enter the appropriate boot command.
Step 9
Booting from a TFTP Server
If you saved the PRE4 image on a TFTP server that is reachable from the router (for example, if the
router and server are on the same LAN or there is a default proxy server), boot the router from the TFTP
server.
In the following example, the router boots the PRE4 image from a network server with the IP address

When the PRE3 is removed from the chassis, any local configuration will be lost. You must
save your configuration to a TFTP server.
A PRE3 is hot-swappable. However, we recommend that you power down the router to ensure a
successful installation when removing a PRE3.
