The server does not turn on. Verify that:
v The power cords are properly connected to the server.
v
The electrical outlet functions properly.

If you just installed an option, remove it, and restart the server. If the server now
turns on, you might have installed more options than the power supply supports.
If the problem remains, call for service.

the problem remains, the LED will be lit again. See the
