Netfinity 3500 - Symptom-to-FRU Index

Applicable to: World-Wide

Symptom-to-FRU Index

Notes
1. This index supports the Netfinity 3500 - Type 8644.
2. Always start with General Checkout on page 4.
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.
XX used in place of the last 2 digits can be any number or letter.
3. For IBM devices not supported by this Symptom-to-FRU Index, refer to the manual for that device.
