2. Press the power on/off switch on the front panel of the server. The power lamp
goes out.
3. Power off the peripheral devices.
Note:
If the server power cord is connected to a power
control unit such as an UPS (Uninterruptible Power Supply),
refer to the UPS user's guide for proper power-off procedures.
Forcing a Power Shutdown
A forced power shutdown can be used when the power on/off switch does not power
off the server or the reset functions do not work.
To perform a forced power shutdown:
■
Press in on the power on/off button located on the front panel of the server for at
least 4 seconds to force the server power off.
To power on after a forced shutdown, wait 10 seconds and then power on again.
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 splash screen 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 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.
POST Execution Flow
The following describes the progress of POST in the chronological order.
Caution
■
Do not make key entries or perform mouse operations while
POST is in progress.
