Map 1540: Minimum Configuration - IBM RS/6000 44P 270 Service Manual

MAP 1540: Minimum Configuration

Notes:
1. Be sure to unplug the power cable before removing or installing processor card(s),
memory card(s), system board or I/O board, to avoid damage to them.
2. This MAP assumes that a CD-ROM drive is installed and connected to the
integrated SCSI adapter, and a diagnostic CD-ROM is available.
3. If a power-on password or privileged-access password is installed, you are
prompted to enter the password before the diagnostic CD-ROM can load.
4. The term "POST indicators" refers to the icons (graphics display) or device
mnemonics (ASCII terminal) that appear during the power-on self-test (POST).
5. The service processor might have recorded one or more symptoms in its error log.
It is a good idea to examine that error log before proceeding (see Service Processor
System Information Menu).
6. The service processor might have been set by the user to monitor server operations
and to attempt recoveries. You might want to disable these actions while you
diagnose and service the system. If you disable them, make notes of their current
settings so that you can restore them before you leave. The following are the
settings:
Surveillance
Unattended Start Mode
Reboot Policy
Call Out
50
