Firmware Upgrade Recovery

There are basically three conditions that call for firmware upgrade recovery:

 When you invoke Firmware Upgrade Mode (see p. 29), but decide not to

proceed with the upgrade.

 When the Mainboard firmware upgrade fails.

 When the I/O firmware upgrade fails.

To perform a firmware upgrade recovery, do the following:

1. Slide the Firmware Upgrade Recovery Switch (see p. 6) to the Recover

position.

2. Power off and restart the switch according to the instructions given in the

Powering Off and Restarting section (p. 18).

3. Slide the Firmware Upgrade Recovery Switch back to the Normal

position.

4. Repeat Step 2.

Note: If one of the child units fails to upgrade successfully, unchain it from the

installation and perform the recovery and upgrade operation on it

independently. After it has been successfully upgraded, plug it back into

the chain
