3. Turning On the Server
3.1 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, DIMM, and processor (CPU).
POST also displays the start-up messages of various utilities during the operation.
Usually, you do not need to check the contents of POST. However, check messages displayed on POST in
the following cases.
• When introducing a server
• When you suspect a failure
• When any error message is displayed
3.1.1 POST flow
Explains how POST runs in order.
1. When the server is turned on, POST starts running.
Keyboard becomes operable after the POST screen appears.
2. If Enabled is specified for Password On Boot in Security menu of SETUP, you will be prompted to
enter password after the POST 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.
Do not set a password before OS is installed.
3. If Quiet Boot is Enabled on Boot menu in BIOS SETUP, the NEC logo is displayed during POST.
Pressing the <ESC> key hides logo and displays the details of POST.
By the shipping default, the logo is not displayed without requiring <ESC> key to be
pressed. The details of POST is displayed instead.
4. POST displays several types of message. These messages let you know that the installed CPU or
capacity of installed memory are detected.
5. After a while, the following message is displayed on the screen.
Press <F2> SETUP, ... (The rest of message depends on system environment.)
By pressing the designated function key following messages, you can call the functions below upon
completion of POST.
<F2> key: Run BIOS Setup Utility (SETUP). For information on the SETUP, refer to Chapter 2 (1.
System BIOS) in "Maintenance Guide".
