Purpose Of This Map; Step 1540-1 - IBM RS/6000 44P 270 Service Manual

Purpose of this MAP

This MAP is used to locate defective FRUs not found by normal diagnostics. For this
procedure, diagnostics are run on a minimally configured system. If a failure is detected
on the minimally configured system, the remaining FRUs are exchanged one at a time
until the failing FRU is identified. If a failure is not detected, FRUs are added back until
the failure occurs. The failure is then isolated to the failing FRU.
