POST
Power-On Self-Test (POST) is a self-diagnostic program stored in the server as standard. POST automatically
runs immediately after the server is turned on and checks the motherboard, memory, processor (CPU),
keyboard, and mouse. POST also displays the start-up messages of different utilities during the operation.
Usually, you do not need to check the contents of POST.
However, check messages displayed at POST in
the following cases.
•
When introducing a server
•
If you suspect a failure
•
When you hear beep many times during the time between Power ON and OS startup
•
When any error message is displayed

POST sequence
Explains how POST runs in order.
1.
Turn on the server. POST starts running and the initialization
message indicating that modules such as the memory and PCI
device are being initialized is displayed. Following the
initialization message, the NEC logo is displayed.
Note
•
Keyboard becomes operable after the logo appears.
•
The screen might go black several times while the initialization message is
displayed. This does not cause any operational problems.
•
The initialization message might not be displayed when the optional VGA
controller is connected or depending on the settings specified by using the BIOS
setup utility (SETUP).
•
The initialization message is not displayed on the serial port console redirection
screen.
2. If
Enabled
is specified for
Password On Boot
in
Security
menu of SETUP, you will be prompted to enter
password after the logo is displayed. If you enter the incorrect password three times consecutively,
POST
aborts.
(You can no longer proceed.) In this case, power off the server, and power it on.
Important Do not set a password before OS is installed.
3.
If <Esc> key is pressed, the logo disappears and the details of POST are displayed.
Tips
If
Quiet Boot
is
Disabled
from
Boot
menu in BIOS settings, the logo is not
displayed without requiring <ESC> key to be pressed.
4.
POST displays several types of message. These messages let you know that the installed CPU or
connected keyboard and mouse are detected.
