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

b. Boot the image from the flash-based media card in the ESR-PRE2 in slot B. The redundant

ESR-PRE2 in slot B comes up as the secondary PRE, and the configuration synchronizes

automatically between the two PREs.

If you do not have any removable media devices, then you upgrade this redundant ESR-PRE2 as if it was

a single ESR-PRE2:

a. Remove the ESR-PRE2 from slot A and go to Step 7 of the “Upgrading the Primary PRE to an

ESR-PRE2” section on page 26. Follow the single board upgrade procedures for the ESR-PRE2 in

slot B.

b. Insert the ESR-PRE2 back into slot A. This redundant ESR-PRE2 in slot A now comes up as the

secondary PRE, and the configuration is synchronized automatically between the PREs.

Note If you desire the primary ESR-PRE2 to be in slot A, you can perform a switchover from the

console at this point.

The redundant ESR-PRE2 upgrade is now complete, and the router is available to resume normal

operations.

Reversing an Upgrade to an ESR-PRE2

Use the following procedure to reinstall an ESR-PRE or ESR-PRE1 (or redundant PREs) after upgrading

to an ESR-PRE2.

Step 1 Power down the router.

Step 2 Remove the ESR-PRE2 (or both ESR-PRE2s in a redundant configuration) from the chassis.

Step 3 Insert the original ESR-PRE(s) or ESR-PRE1(s) back into the chassis. If you swapped flash-based media

cards to the ESR-PRE2(s) during the upgrade, remove them from the ESR-PRE2(s) and insert them back

into the appropriate ESR-PRE(s) or ESR-PRE1(s).

Step 4 Power on the router. The router loads as it originally did before the upgrade.

Troubleshooting the Installation

Refer to Table 4 for descriptions of the LEDs on the PRE. Follow the instructions in Table 5 on the next

page to troubleshoot the installation.
