MAP 1540: Problem Isolation Procedures

These procedures are used to locate problems in the processor subsystem, I/O subsystems, or rack. If a
problem is detected, these procedures help you isolate the problem to a failing unit. Find the symptom in
the following table; then follow the instructions given in the Action column.
Attention: To identify a FRU, these MAPs refer to FRU Identify LEDs. For more Information about the
FRU Identify LEDs see "FRU Identify LEDs" on page 54.
