Firmware Upgrade Recovery
There are three conditions that call for firmware upgrade recovery:
•
When a firmware upgrade is manually aborted.
•
When the main board firmware upgrade fails.
•
When the I/O firmware upgrade fails.
To perform a firmware upgrade recovery, do the following:
1.
Power off the switch.
2.
Connect the Firmware Upgrade Cable to its Firmware Upgrade Port.
3.
Slide the Firmware Upgrade Recovery Switch to the Recover position.
4.
Power the switch back on and repeat the upgrade procedure.
5.
After the switch has been successfully upgraded, power it off, and slide the Firmware Upgrade Recovery
Switch back to the Normal position.
6.
If the switch is one of the cascaded switches, plug it back into the installation.
7.
Power the switch back on.
