MAP 1540:7012 G Series Minimum Configuration

Note: This is not a start of call MAP. You should use this MAP only if you have been
directed here from a MAP step in the Diagnostic Information For Micro Channel Bus
Systems .
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 minimum-configured system. If a failure is detected on
the minimum-configured system, the remaining FRUs are exchanged one at a time until the
failing one 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.
The MAP steps on the following pages instruct you to reduce the system to one or more of
the following configurations:
Minimum Configurations for the 7012 G Series Systems:
– System planar, operator panel, CPU card, and memory card.
If no failure is detected, the maintenance menu is displayed. Any other response
means one of the remaining FRUs is failing.
– System planar, operator panel, CPU card, memory card, and a BUMP console
attached to the S1 port.
– System planar, operator panel, CPU card, memory card, CD-ROM drive, SCSI adapter
and a BUMP console attached to the S1 port.
If no failure is detected, the Diagnostic Operating Instructions frame is displayed when
the diagnostics are loaded, and the system console is selected. Any other response
means that one of the remaining parts is failing.
