After a few seconds your system begins the internal Power-On Self Tests (POST).
POST automatically checks the system board, CPU(s), memory, keyboard, mouse, and
most installed peripheral devices. POST also displays the start messages of the BIOS
setup utility during execution.
The POST check results should be checked in the following cases:
■
When the server is being used for the first time.
■
When the server appears to fail.
■
When the server beeps many times between power-on and OS start-up.
