Applicable to: World-Wide

Symptom-to-FRU index
This index supports the Netfinity 1000 - Type 8477.


Notes
1. Check the configuration before you replace a FRU. Configuration problems can cause false errors and symptoms.
2. For IBM devices not supported by index, refer to the manual for that device.
3. Always start with General checkout.


The Symptom-to-FRU Index lists beeps, errors, symptoms, 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.
