MAP 1540: Minimum Configuration
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.
Notes:
1. Be sure to unplug the power cable before removing or installing the Service
Processor, processor card(s), memory card(s), System board or I/O board to
avoid damaging them.
2. This MAP assumes that a CD-ROM drive is installed and connected to the inte-
grated SCSI adapter connector (port 1), and a Diagnostics CD-ROM disc is avail-
able.
3. If a power-on password or privileged-access password is installed, you are
prompted to enter the password before the diagnostic CD-ROM loads.
4. The term "POST indicators" refer to the icons (graphic display) or device mne-
monics (ASCII terminal) that appear during the power-on self-test (POST).
5. The Service Processor may have recorded one or more symptoms in its error
log. It is a good idea to examine that error log before proceeding (see “System
Information Menu for Model H50” on page C-13 or “System Information Menu for
Model H70” on page C-15).
6. The Service Processor may have been set by the user to monitor server oper-
ations and to attempt recoveries. You may wish to disable these actions while
you diagnose and service the system. If you disable them, you should make
notes of their current settings for restoration before you leave. Following are the
settings of your interest.
Surveillance From the service Processor Setup Menu, go to the Surveillance Setup Menu
and disable surveillance.
Unattended
Start From the Service Processor System Power Control Menu disable unattended
start mode.
Reboot Policy From the System Power Control Menu go to the Reboot/Restart Policy Setup
Menu and set:
1. Number of reboot attempts to 0 (zero)
2. Use OS-Defined restart policy to No
3. Enable supplemental restart policy to No.
