Undetermined Problems (Server 315, 330)

Undetermined Problems

You are here because the diagnostic tests did not identify the failure, there is no Devices List, or the system is inoperative.

NOTE: 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:

For Server 315 see > Power Supply Voltages
For Server 330 see > Power Supply Voltages

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).
- Non-IBM devices
- External devices (modem, printer, mouse...)
- Any adapters
- Riser card
- Memory modules
- Extended video memory
- Hard disk drive
- Diskette drive
NOTE: The minimum operating requirements for the PC Server 315-8638 -or- 330-8640 are:
- System board
- Processor board with:
  - Processor
  - 1 memory DIMM
- Cooling fan
Power-on the computer. If the problem remains, suspect the system board, then the processor board in that order.

NOTE: 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.
