POST

POST (Power On Self-Test) is the self-diagnostic program stored in the CPU blade.
When you power on the CPU blade, the system automatically runs POST to check the motherboard, memory
module, processor (CPU), keyboard, and mouse. POST also displays the start-up message of utilities, while in
progress.
Usually, you do not need to check the contents of POST. However, check messages displayed at POST in
the following cases.
When you use the CPU blade for the first time.
When the CPU blade appears to fail.
When any error message is displayed

1.5.1 POST Execution Flow

The following describes the progress of POST in the chronological order.
Important
1. When the server is turned on, POST runs.

displayed.
Tips
86
Do not make unnecessary key entries or perform mouse operations while
POST is in progress.
Some system configurations may display the message "Press Any Key" to
prompt a key entry. This message is driven by BIOS of an installed optional
board. Make sure to read the manual that comes with the optional board before
any key entry.
Powering on the server, after you installed or removed an optional mezzanine
card, may display the message that indicates incorrect board configuration
and suspend POST.
In such a case, press the <F1> key to continue POST. Board configuration can
be made using the utility described later.
You can set it to show the details of POST to be displayed from BIOS menu without
requiring the <ESC> key to be pressed. From the System BIOS Setup, set Quiet Boot to
Disabled in the Boot menu.
