Service processor error codes

When viewed from POST, Remote Supervisor Adapter error codes will appear in
hexadecimal form (generally beginning with A2, A3, A4, A5, A6, A7, AD, AE, or E1).
However, when viewed from the System Error Log, the messages will appear as
text. To determine a possible error condition for the service processor, see the
System Error Log (see "Viewing error logs from diagnostic programs" on page 22).

SCSI error codes

Error code
All SCSI Errors One or more of the
following might be causing the problem:
v A failing SCSI device
(adapter, drive, controller)
v An improper SCSI configuration or SCSI
termination jumper setting
v Duplicate SCSI IDs in the same SCSI
chain
v A missing or improperly installed SCSI
terminator
v A defective SCSI terminator
v An improperly installed cable
v A defective cable

Temperature error messages

Note: See "System replaceable units" on page 122 to determine which components should be replaced by a field
service technician.

FRU/action
1. External SCSI devices must be turned on before you turn on the
server.
2. Make sure that the cables for all external SCSI devices are
connected correctly.
3. If you have attached an external SCSI device to the server, make
sure the external SCSI termination is set to automatic.
4. Make sure that the last device in each SCSI chain is terminated
correctly.
5. Make sure that the SCSI devices are configured correctly.
