Maintenance Analysis Procedures (MAPs)
MAP 1540: 7015 CPU Enclosure – 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 7015 CPU Enclosures:
Notes:
Install the memory cards in a right-to-left sequence beginning with slot A, and then
continuing with slots B, C, and D. Memory cards must be installed with no empty
slots between installed memory cards.
Install the CPU cards in a right-to-left sequence beginning with slot P, and then
continuing with slots Q, R, and S. CPU cards must be installed with no empty slots
between installed CPU cards.
– Power distribution cable cluster, system planar (SP), I/O planars, I/O card (IOC), CPU
module flex cables, I/O module flex cables, system interface board (SIB), operator
panel , one CPU card (CPU), one memory card (MC), and power supply (PS).
If no failure is detected,
the maintenance menu
is displayed. Any other response
means one of the remaining FRUs is failing.
– Power distribution cable cluster, system planar (SP), I/O planars, I/O card (IOC), CPU
module flex cables, I/O module flex cables, system interface board (SIB), operator
panel , one CPU card (CPU), one memory card (MC), power supply (PS), CD-ROM
drive, SCSI adapter, and a system 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 one of the remaining FRUs is failing.
