POST
POST (Power On Self-Test) 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, and processor (CPU).
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. When the server is turned on, POST starts running. It displays messages indicating initialization of
memory and PCI devices. After these messages are displayed, the logo appears on the screen.
Note
•
Keyboard becomes operable after the logo appears.
•
The screen may change to solid black (with no display) while the initialization
messages are displayed. However, it does not affect system operation.
•
The initialization message may not be displayed depending on settings in BIOS
SETUP, or optional VGA controller is connected.
•
The initialization message is not displayed on 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

without requiring <ESC> key to be pressed.
