1. If you press
[F1]
and nothing happens, confirm the following:

The keyboard is not locked, and network server mode is not enabled. (If either the keyboard
lock or network server mode was enabled in the

experienced a fatal POST error. If this happens, refer to the Beep Code table for the symptom:
3. Turn off the Netserver, unplug the power cord, and do the following:
◊◊◊◊
Remove and reinsert the only PCI accessory board firmly in the slot.
◊◊◊◊
Remove and reinsert the processor(s) firmly in the sockets on the system board.
◊◊◊◊
Remove and reinsert the DIMMs firmly and correctly in the slots.

have caused error messages to be unreadable.
