System Overview 1-33

POST

POST (Power On Self-Test) is the server's self-diagnostic program stored in the system memory.

When you power on the server, the system automatically runs POST to check the system 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.)

NOTE: You can set the POST check results to appear on the display unit without pressing Esc. To do so, select "Enabled" for "Boot-time Diagnostic Screen" under the Advanced menu of the BIOS setup utility.

You don't always need to check the POST check results. Check messages that POST displays when:

!You use the 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.
