8.5 Firmware Upgrade Recovery
A firmware upgrade recovery is required in any of the following situations:
When you invoke Firmware Upgrade Mode (see page 22), but decide not to proceed with the upgrade. •
When the main board firmware upgrade fails. •
When the I/O firmware upgrade fails. •
To perform a firmware upgrade recovery, do the following:
Slide the 1. Firmware Upgrade Recovery Switch (see page 7) to the Recover position.
Power off and restart the switch according to the instructions below: 2.
• Shut down all the computers that are attached to it.
Note: Unplug the power cord of any computer that has the Keyboard Power On function. Otherwise, the KVM will still receive power
from this computer.
Wait 10 seconds, then plug the KVM switch back in. •
Once the switch is up, the computers can be powered On. •
Note: If you have shut down more than one Station, power up the highest Station first and work your way down to the lowest one.
Slide the 3. Firmware Upgrade Recovery Switch back to the Normal position.
Repeat Step 2. 4.
Note: If one of the slave units fails to upgrade successfully, unchain it from the installation and perform
the recovery and upgrade operation independently. After it has been successfully upgraded, plug it back
into the chain.
