Maintenance approach
The diagnostic information in this manual leads 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. See
“Diagnostic information” on page 2-1 for more information. See “Repair information” on page 4-1 for the
steps to replace FRUs. After completing the repair, perform tests as needed to verify the repair. See “Parts
catalog” on page 7-1 to help identify part numbers if parts need to be replaced
