Step 1548-22
The adapter or device is probably defective.
If the supplemental media is for an adapter, replace the FRUs in the following order:
1. Adapter
2. CEC backplane (see notes on page 61)
If the supplemental media is for a device, replace the FRUs in the following order:
1. Device and any associated cables
2. The adapter to which the device is attached
Repeat this step until the defective FRU is identified or all the FRUs have been exchanged.
If the symptom did not change and all the FRUs have been exchanged, call service support for assistance.
If the symptom has changed, check for loose cards, cables, and obvious problems. If you do not find a
problem, go to the "Quick Entry MAP" on page 63 and follow the instructions for the new symptom.
Go to "MAP 0410: Repair Checkout" in the RS/6000 Eserver pSeries Diagnostic Information for Multiple
Bus Systems.
