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, DIMM, 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, and an initialization
message is displayed. The message to tell initialization of
a memory and a PCI device. After an initialization message
was displayed, a logo appears on the 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.
3. If <Esc> key is pressed, the logo disappears and the details of POST are displayed.
Note
 Keyboard becomes operable after the logo appears.
 While an initialization message is displayed, a screen is sometimes switched
over to the screen by which nothing is displayed (black screen) several times. It's
no problem for operation.
 An initialization message and logo may not be displayed by the occasion with
which an option VGA controller was connected and setting of a BIOS setup utility
(SETUP).
 An initialization message is not displayed on the console redirection screen of a
serial port.
Important
Do not set a password before OS is installed.
Tips
If Quiet Boot is Disabled from Boot menu in BIOS settings, the logo is not
displayed and POST execution result is displayed..
