POST (Power-On Self-Test) is a self-diagnostic program stored in the server as standard. POST
automatically runs immediately after the server is turned on and checks the motherboard, memory, and
processor (CPU). POST also displays the start-up messages of different utilities during the operation.
Usually, you do not need to check the contents of POST.
However, check messages displayed at POST
in the following cases.
•
When introducing a server
•
If you suspect a failure
•
When you hear beep many times during the time between Power ON and OS startup
•
When any error message is displayed
