Maintenance Approach
The diagnostic information in this manual leads you to the correct
field replaceable unit (FRU) or part. Use the error code charts,
symptom index, and service checks to determine the symptom and
repair the failure. The removals in the Repair Information chapter
may help you identify parts.
After you complete the repair, perform tests as needed to verify the
repair.
