IBM 3745 Series, Installation And Maintenance Manual

Page: 124 / 270

Note
The service processor based on 6563 computer is default to come up quiet (No
beep and no memory count and checkpoint code display) when no errors are
detected by POST.
To enable Beep and memory count and checkpoint code display when a
successful POST occurs:
1. Enable Power on Status in setup. See “Service Processor Configuration /
Setup Utility” on page H-9.
Error Code Format
This section provides an explanation of the encoded non-SCSI and SCSI POST
error codes.
Error messages are displayed on the screen as three, four, five, eight, twelve, or
thirteen digits. An “X” in an error message can be any number or letter. The
shorter POST errors are highlighted in the Symptom-to-FRU Index. Some digits
will represent different information for SCSI errors versus non-SCSI errors.
The following figure shows which digits display the shorter POST errors. The figure
also defines additional SCSI information.
Notes
¹
Non-IBM device error codes and documentation supersede this list.
¹
Duplicate SCSI ID settings will cause misleading error symptoms or
messages.
