Purpose of this MAP

This MAP is used to locate defective FRUs not found by normal diagnostics. For t 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 detec added back until the failure occurs. The failure is then isolated to the faili

for the Model 140 and Model 240 differ, this

is

divided into 1540A for

the

Model

140 and 1540B for the

Model 240.
