Firmware Upgrade Recovery
There are basically three conditions that call for firmware upgrade recovery:
w
When you begin a firmware upgrade, but decide not to proceed with it.
w
When the Mainboard firmware upgrade fails.
w
When the I/O firmware upgrade fails.
Note: If one of the cascaded switches fails to upgrade successfully, unplug it
from the installation and perform the recovery and upgrade operation
independently. After it has been successfully upgraded, plug it back into
the installation.
To perform a firmware upgrade recovery, do the following:
1. Slide the Firmware Upgrade Recovery Switch (see p. 8) to the Recover
position.
2. Power off and restart the switch.
3. Repeat the upgrade procedure from Starting the Upgrade, p. 38.
4. Power off the switch.
5. Slide the Firmware Upgrade Recovery Switch back to the Normal position.
6. Power the switch back on.
