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.
While the memory is being tested, the amount of available
memory appears on the screen. These numbers advance
as the server progresses through POST and the final
number that appears on the screen represents the total
amount of memory available. 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 information LED panel.
If POST detects a problem, more than one beep sounds
and an error message appears on the screen.
Note
A single problem might cause several error messages.
When this occurs, work to correct the cause of the first
error message. After the cause of the first error
message is corrected, the other error messages
usually will not occur the next time you run the test.
For a list of error codes and messages, see
“Symptom-to-FRU index” on page 285.
POST beep codes
POST generates beep codes to indicate successful
completion or the detection of a problem.
Ÿ
One beep indicates the successful completion of
POST.
Ÿ
More than one beep indicates that POST detected a
problem. For a list of error codes and messages, see
“Symptom-to-FRU index” on page 285.
Error messages - descriptions
Error messages indicate that a problem exists; they are not
intended to be used to identify a failing part.
Troubleshooting and servicing of complex problems
indicated by error messages should be performed by
trained service personnel.
Hardware error messages that occur can be text, numeric,
or both. Messages generated by the software generally
are text messages, but they also can be numeric.
