NEC Express 5800/120Lh, User Manual, Page: 65 / 314

Setting Up Your Server 3-11
The POWER/SLEEP lamp on the front of the server comes on.
In a few seconds, the NEC logo appears on the screen and the Power On Self-Test (POST)
begins.
The POST runs automatically when you power on the server or reset it with a keyboard
operation (
Ctrl + Alt + Delete ). The POST runs diagnostics, initializes the server, sets
interrupt vectors, detects installed peripheral devices, and boots the operating system (if
installed). See Chapter 2 for detailed description on POST.
If the server halts before completing the POST, the POST emits a beep code indicating a
fatal system error requiring immediate attention. (See Chapter 8, "Troubleshooting," for
troubleshooting information.)
During memory test, the POST displays the amount of memory it was able to access and
test. Depending on the amount of installed memory, it may take several minutes to
complete the memory test.
NOTE:
The factory-set is defined to hide the POST screen with the
NEC logo screen. You can always change the NEC logo screen to the
POST screen by pressing
Esc
. To change the start-up screen, use the
BIOS setup utility, "SETUP." (See Chapter 4 for details.)
During the POST, you will see the banner message to prompt you to launch the BIOS SETUP utility
stored in ROM on system board or on an installed option board.
Start the BIOS SETUP utility appropriate to your system environment to change the BIOS setup.
For the BIOS SETUP for the server, see Chapter 4. For the BIOS SETUP for the option board,
refer to the manual that comes with the option board.
IMPORTANT:
Always allow POST to complete before turning off
your system.
