Netfinity 3500 - Undetermined Problems

Applicable to: World-Wide

Undetermined Problems
You are here because the diagnostic tests did not identify the failure, the Devices List is incorrect, or the system is inoperative.

Notes If you suspect a software mismatch is causing failures (solid or intermittent), be sure to see "Resolving Configuration Conflicts".

Check power supply. If the LEDs indicate the power supplies are working correctly, 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 (Minimum requirement = 1 bank of 64 MB DIMMs)

Note Minimum operating requirements vary for each computer. For example, an IML drive in the drive startup sequence (IML systems only).

3. Power-on the computer. If the problem remains, suspect the following FRUs in the order listed:
System Board
Processor Board
Front Panel

Note If the problem goes away when you remove an adapter from the system, and replacing that adapter does not correct the problem, suspect the system board then the processor board(s)
