PC Server 330 - Undetermined problems

Applicable to: World-Wide

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. 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:
1. Power-off the computer.
2. 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
- Drives
- Memory-Module Kits

Note: The minimum operating requirements for the PC Server 330 - Type 8640 are: System board Processor board with: - Processor - 1 memory DIMM Cooling fan

3. 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.
