POST
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of tests
is called the power-on self-test, or POST.
If POST finishes without detecting any problems, a single beep sounds, the first
screen of your 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 your screen. See “POST beep code descriptions” on page 82 and “POST
error messages” on page 85 for more information.
Notes:
1. If you have a power-on 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.
