TP 760C/CD/L/LD/E/ED/EL/ELD - System board & CPU checkout
Applicable to: World-Wide
The following information is intended for IBM Dealers and Authorized Servicers only. Customers attempting to follow any of the procedures below may void their warranty.
System Board and CPU Card Checkout :
The processing functions are performed by both the system board and the CPU card. Processor problems can be caused by either FRU. However, the CPU card generally has a lower probability of failure. When a numeric code calls the system board or the CPU card as a FRU, or the CPU card is called by a diagnostic test by showing FRU code 11, use the following procedure to isolate then problem.
1. Run the system board test to verify the symptom. This test verifies both the system board and the CPU card.
2. If FRU code 10 appears, replace the system board but do not replace the CPU card. Transfer the CPU card from the old system board to the new system board.
3. If FRU code 11 appears, reseat the CPU card.
4. Rerun the test to verify the fix.
5. If FRU code 11 remains, replace the CPU card.
If above procedure does not correct the problem, go to "Undetermined Problems"
