You are here because the diagnostic tests did not identify the
failure, there is no Devices List, or the system is inoperative.
If you suspect a software mismatch is causing failures (solid or intermittent),
be sure to see 'Software Hardware Mismatch Problems'.
Check the power supply voltages. See Power Supply Server 325 or
If the voltages are not correct, replace the power supply.
If the voltages are correct, return here and do the following:
- Power-off the computer.
- Remove or disconnect the following (one at a time) until you find the
failure (power-on the computer and reconfigure each time).
- Any external devices
- Surge suppressor device (on the computer)
- Modem, printer, mouse, or non-IBM devices
- Each adapter
- Memory-Module Kits
Minimum operating requirements for the PC Server 325, Type 8639
- System board
- Processor board with:
- Cooling fan
- Power-on the computer. If the problem remains, suspect the system board,
then the processor board in that order.
If the problem goes away when you remove an adapter,
and replacing that adapter does not correct the problem,
suspect the system board or processor board.
