Cisco 10000 Series Router Performance Routing Engine Installation

OL-3971-03

Upgrading from an ESR-PRE or ESR-PRE1 to an ESR-PRE2

Note The config-register of a new ESR-PRE2 (shipped from the factory) is set to 0x0. If your

ESR-PRE2 is not new from the factory, and the config-register is not set to 0x0, it may behave

differently while booting up.

Step 8 From the console in ROM monitor mode, enter the appropriate boot command, depending on whether

you saved the ESR-PRE2 image to a TFTP server or a flash-based media card, or whether you did not

save the ESR-PRE2 image.

Booting from a TFTP Server

If you saved the ESR-PRE2 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 ESR-PRE2 (c10k2-p11-mz) image from a network server

with the IP address 172.16.15.112:

> boot tftp://172.16.15.112/c10k2-p11-mz

The configuration dialog appears.

You can now proceed to step 9.

Booting from a Flash-Based Media Card

If the image was saved to the flash-based media card, boot that image.

The following boot command loads the ESR-PRE2 image from the media card:

> boot system flash disk0:c10k2-p11-mz

The configuration dialog appears.

You can now proceed to step 9.

Booting from the Helper Image

If you did not save the ESR-PRE2 image to either a TFTP server or a flash-based media card, boot the

helper (c10k-eboot-mz) image, which is shipped with the ESR-PRE2 boot flash memory.

In the following example, the router boots from the helper image:

> boot c10k-eboot-mz

The configuration dialog appears.

Proceed to the “Did Not Save the Configuration” section on page 28.

Step 9 Restore the startup and running configuration of the router, depending on whether you saved the

ESR-PRE2 image to a TFTP server or a flash-based media card, or you did not save the ESR-PRE2

image.

Saved the Configuration on a Flash-Based Media Card

If you booted the c10k2-p11-mz image, and you saved the previous configuration to a flash-based media

card:

a. Exit the configuration dialog and restore the previously saved startup and running configuration

from the media card.

b. Update any boot commands to use the new ESR-PRE2 (c10k2-p11-mz) image.
