When using Firmware Update software you may at times get a Communication Error message.
If a Communication Error message does appear during the update procedure, do the following:

2. Ensure that the RS232 Serial cable's DB9F connector is connected to the DB9M Serial port on the CPU's rear panel.
3. Verify there is no Remote session in progress by pressing the Local button.
4. Restart the download process.
Electricity Failure
If the electricity fails during an update to the KVM fi rmware, do the following:
1. If the electricity fails while the switch fi rmware is updating, a Communication Error message will appear. Simply resume the fi rmware update by opening the
folder that contains the fi rmware update fi le and continue from there.
2. If the electricity fails while the Server Interface Unit fi rmware is updating, a Not Responding or Upgrade Error message will appear. Restart the upgrade from
the beginning.
Monitor Screen Failure

Display Video Mode'), you may need to update the DDC Information from the console monitor. To do this, follow these steps:
1. Remove the SIU VGA Connectors from all connected computers. Leave the USB or PS/2 connectors attached
2. Open the OSD Main Menu and press the F10 key. The OSD will fl ash the message 'Please Wait.' When that message stops, the update has taken place
