Before Having the Unit Repaired
Before asking for repair, do the following when the server switch unit appears to fail:
1.
Check if the AC cord, the interface cables connected to the server, and the consoles are
properly connected.
2.
See "Troubleshooting" to find if your problem fits the description. If it does, take the
recommended measure for it.
3.
Check if the software required for operation of the server switch unit is properly installed in
the server.
If the server switch unit still appears to fail after you have taken the above actions, consult with your
service representative immediately. Take notes on lamp indications of the server and alarm
indications on the display unit before consultation, which may provide a significant help to your sale
agent.
