Step 1540-23
The adapter or device is probably defective.
If the supplemental medium is for an adapter, replace the FRUs in the following order:
1. Adapter
2. System board (see notes on page 35)
If the supplemental medium 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, return to “Step 1540-1” on page 64 in this MAP and follow
the instructions for the new symptom.
