Power-on self-test (POST)
When you turn on the server, the power-on self-test (POST) performs a series of
tests to check the operation of the server components and some of the installed
options.
If POST finishes without detecting any problems, the first window of your operating
system or application program opens.
If POST detects a problem, more than one beep might sound, an error message
might appear on your screen, or both.

If you have set a user password, you must type the password and press Enter,
when prompted, before the operating system will start.
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 typically will be resolved the
next time you run the test.
POST was completed successfully.
