2-14 General Description
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 the POST to check the mother board, ECC memory
module, CPU module, keyboard, and mouse. The 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, a full-screen logo appears on the display unit while the 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 the messages displayed by the POST when:
îš„ you use the server for the first time.
îš„ the server appears to fail.
îš„ the server beeps many times between power-on and OS start-up.
îš„ an error message appears on the display unit.
