MAP 1540: Minimum Configuration
Notes:
1. This MAP assumes that a CD-ROM drive is installed and connected to the
integrated SCSI adapter, and a Diagnostics CD-ROM disc is available.
2. If a power-on password or privileged-access password is installed, you will be
prompted to enter the password before the diagnostic CD-ROM will load.
3. The term "POST indicators" refer to the ICONs (graphic display) or device
mnemonics (ASCII terminal) that display while the POST is executing.
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.
The MAP steps on the following pages instruct you to reduce the system to one or
more of the following configurations:
Ÿ
System board, CPU card, 1 memory module.
If no failure is detected, the green power LED will be on and the system will
beep twice (one short beep, followed by one long beep up to a minute or more
later). Any other response means one of the remaining FRUs is failing.
Ÿ
System board, CPU card, all memory modules and a terminal attached to the S1
port or a keyboard, display, and graphics adapter.
If no failure is detected, The power LED will be on and the system will beep
twice (one short, followed by one long beep up to a minute or more later). The
SMS screen will be displayed.
Ÿ
System board, CPU card, all memory modules, CD-ROM drive, and a terminal
attached to the S1 port or a keyboard, display, and graphics adapter.
If no failure is detected, The power LED will be on and the system will beep
twice (one short, followed by one long beep up to minute or more later). The
POST indicators will be displayed. After the CD-ROM loads a screen titled
"Please define the System Console" will be displayed. Any other response
means one of the remaining FRUs is failing.
