2-20 General Description
POST
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 mother board,
ECC memory module, CPU module, keyboard, and mouse. POST also displays messages of the
BIOS Setup utility, such as the start-up message, while in progress.
With the factory setup of the server, the NEC logo appears on the display unit while POST is in
progress. (To display the POST check results, press
Esc .)
You don't always need to check the POST check results. Check messages that POST displays when:
„
you use the NEC Express server for the first time.
„
the server appears to fail.
„
the server beeps for many times between power-on and OS start-up.
„
an error message appears on the display unit.
