Service processor error codes
When viewed from POST, service processor 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 the diagnostic programs” on page 32).
SCSI error codes
Note: If a ServeRAID-5i controller is installed and later removed, you must
re-enable the on-board SCSI controller in using the Configuration/Setup
