Symptom-to-FRU index
Notes:
1. Check the configuration before you replace a FRU. Configuration problems can
cause false errors and symptoms.
2. The default configuration can be loaded by starting the system and then
pressing the reset button four times, waiting 15 seconds between each press.
Once the configuration has reset to the default, it must be saved in Setup to be
stored in CMOS.
3. For IBM devices not supported by index, refer to the manual for that device.
4. Always start with “General checkout” on page 1.
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 displays
POST error codes and messages on the screen.
Beep symptoms
Beep symptoms are short tones or a series of short tones separated by pauses
(intervals without sound). See the following examples.
Note: One beep after successfully completing POST indicates the system is
functioning properly.
