Symptom-to-FRU Index This index supports Netfinity 7000-M10 - Type 8680 servers. 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" on page 6. The Symptom-to-FRU Index 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.
