Firmware Upgrade Recovery

Should the firmware on the switch be missing or corrupted it may not be possible to operate or boot the switch. This could be due to:

ŠStarting the Firmware Upgrade mode (see FIRMWARE UPGRADE, page 43), and then canceling the upgrade.

ŠAn interruption of the firmware upgrade.

ŠThe firmware upgrade procedure failing.

ŠThe unit’s firmware becoming corrupted for unknown reasons.

1.On the KVM Switch slide the Firmware Upgrade Recovery Switch (see page 8) to the Recover position.

2.Power off and restart the switch according to the instructions given in the Powering Off and Restarting section (see page 31).

3.Proceed with the firmware upgrade as described in Performing the Upgrade, starting on page 61.

4.When the upgrade ends, power off the switch
