Netfinity 7000 - Symptom-to-FRU Index

Applicable to: World-Wide

Symptom-to-FRU Index
This index supports Netfinity 7000 - Type 8651 servers.

Note Always start with General Checkout.

The Symptom-to-FRU lists symptoms, errors, and the possible causes. The most likely cause is listed first. Use this Symptom-to-FRU Index to help you decide which FRUs to have available when servicing the computer. The POST BIOS displaying POST error codes and messages on the screen.

Note For IBM devices not supported by index, refer to the manual for that device.

Beep Codes

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 1. If you suspect a software mismatch is causing failures (solid or intermittent), be sure to see "Configuration Conflicts". 2. A corrupt CMOS can cause undetermined problems, go to NVRAM and RTC Settings (Switch S6A1-1) and follow the procedure to reset the server's NVRAM and RTC settings.

Check the LEDs on all the power supplies. 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).
