Recovering from a Failed Firmware Upgrade
If a firmware upgrade procedure is aborted prematurely (due to a power outage,
for example), the KVM switch that was being upgraded at the time may
become inoperable and may be incapable of accepting a normal firmware
upgrade. Follow this procedure to recover from the failed firmware upgrade.
To recover from a failed firmware upgrade:
1. Power off the first-level KM0832. Do not power off the cascaded and
daisy-chained KVM switches (if applicable).
2. Locate the F/W UPGRADE switch on the back panel of the KM0832.
Slide the switch to the RECOVER position.
3. Power on the first-level KM0832.
4. Upgrade the firmware using the Firmware Upgrade Utility.
(See Upgrading Firmware via the Firmware Upgrade Utility, page 76.)
5. When the firmware upgrade recovery completes, the KM0832 will issue a
single continuous beep.
6. Slide the F/W UPGRADE switch to the NORMAL position. The beep will
stop.
7. Power off the first-level KM0832, wait 5 seconds, and then power it on
again.
8. Upgrade the firmware to the latest firmware version. (See Upgrading
Firmware via the KM0832 Administrator Utility, page 74.) If you already
upgraded to the latest firmware version in Step 4, you do not need to
upgrade the firmware again.
