POST
The POST (Power On Self-Test) is the self-diagnostic program stored in the system memory.
When you power on the server, the system automatically runs POST to check the motherboard, ECC memory module,
CPU module, keyboard, and mouse. The POST also displays messages from the BIOS Setup utility, such as the start-up
message, while in progress.
A full screen logo appears on the display unit while POST is in progress. (To display the POST check results, press
Esc.)
You do not always need to check the POST check results. Check the messages displayed by the POST when:
you use the server for the first time.
the server appears to fail.
the server beeps many times between power-on and the OS start-up.
an error message appears on the display unit.
