When you power up the appliance, it performs a series of tests that check the
operation of components and some of the hardware options installed in the
appliance. This series of tests is called the power-on self-test, or POST.
If the POST finishes without detecting any problems, a single beep sounds, and
the first screen of your operating system or application program appears.
If the POST detects a problem, more than one beep sounds, and an error message
appears on your screen. See the
more information.
If you have a power-up password or administrator password set, you must enter
the password and press Enter when prompted, before POST will continue.
A single problem might cause several error messages. When this situation occurs,
you should 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 that you run the test.
The POST error log contains the three most recent error codes and messages that
the system generated during the POST. The system error log contains all messages
issued during the POST and all system status messages from the service
processor.
You can view the contents of the system error log from the diagnostic programs.
