Unknown problem
Action
:
1.
Disconnect power to the server.
2.
Following the guidelines and cautionary information in the server documentation, strip the server to

server. Keep the monitor connected to view the server startup process.
3.
Reconnect power, and then power the system on.

If the system fails in this minimum configuration, one of the primary components has failed. If you

o
If the system boots and video is working, add each component back to the server one at a time,

of the problem. When adding each component back to the server, be sure to disconnect power
to the server and follow the guidelines and cautionary information in the server documentation.
