If POST finishes without detecting any problems, a single beep sounds, the first
screen of the operating system or application program appears, and the System
POST Complete (OK) light is illuminated on the operator information panel.
If POST detects a problem, more than one beep sounds and an error message
appears on the screen. See “POST beep codes” and “POST error messages” for
more information.
Notes:
1. If you have a power-on password or administrator password set, you must
type the password and press Enter, when prompted, before POST will continue.
2.
A single problem might cause several error messages. When this occurs, work
to correct the cause of the first error message. After you correct the cause of the
first error message, the other error messages usually will not occur the next
time you run the test.
POST beep codes
POST generates beep codes to indicate successful completion or the detection of a
problem.
v
One beep indicates the successful completion of POST.
v
More than one beep indicates that POST detected a problem. For more
information, see “Beep symptoms” on page 119.
POST error messages
POST error messages occur during startup when POST finds a problem with the
hardware or detects a change in the hardware configuration. For a list of POST
errors, see “POST error codes” on page 131.
Event/error logs
The POST error log contains the three most recent error codes and messages that
the system generated during POST. The System Event/Error Log contains all error
messages issued during POST and all system status messages from the Netfinity
Advanced System Management Processor.
To view the contents of the error logs, start the Configuration/Setup Utility
program; then, select Event/Error Logsfrom the main menu.
Small computer system interface messages
If you receive a SCSI error message, see “SCSI error codes” on page 138.
Note: If the server does not have a hard disk drive, ignore any message that
indicates that the BIOS is not installed.
You will get these messages only when running the SCSISelect Utility.
Diagnostic programs and error messages
The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the system board. These programs are the primary method of testing the major
components of the server.
