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:
1. Ensure that the RS232 Serial cable's RS232 connector is connected to the Switch's
Communication port.
2. Ensure that the RS232 Serial cable's DB9F connector is connected to the DB9M Serial
port on the CPU's rear panel.
3. Restart the download process.
Electricity failure
If the electricity fails during an update to the KVM firmware, do the following:
If the electricity fails while the switch firmware is updating, a Communication Error message
will appear. Simply resume the firmware update by opening the folder that contains the
firmware update file and continue from there.
If the electricity fails while the Server Interface Unit firmware is updating, a
Not Responding or Upgrade Error message will appear. Restart the upgrade from the
beginning.
Troubleshooting
USB/SUN Combo Keys
The connected PS/2 keyboard does not have a special SUN keypad to perform special
functions in the SUN Operating System environment. So when a RICC USB or SUN is
connected to a SUN computer, the RICC emulates these SUN keys using a set of key
combinations called Combo keys. See the table below.
