Server Starts Booting Automatically at Power On

The server board saves the last known power state in the event of a power failure. If
you remove power before powering down the system using the power switch on the
front panel, your system might automatically attempt to restore itself back to the
state it was in after you restore power.

You can configure how you would like your server system to react when power is
restored in the BIOS set-up (Security menu). You can have the server remain off or
return to the last known power state.

Please keep in mind that unplugging the system or flipping a switch on the
power strip both remove power.

Follow the correct power removal sequence (make sure the system has shut down
before removing the power cord).

Power-On Self-Test (POST)

Each time you turn on the system, the BIOS begins execution of POST. POST
discovers, configures, and tests the processors, memory, keyboard, and most
installed peripheral devices. The time needed to test memory depends on the
amount of memory installed. POST is stored in flash memory.

To execute and monitor POST:

1. Turn on your video monitor and system. After a few seconds, POST begins to run

and displays a splash screen.

2. While the splash screen is displayed:

Press <F2> to enter the BIOS Setup

OR

Press <Esc> to view POST diagnostic messages and change the boot device

priority for this boot only.

OR

If the Service Partition is installed, press <F4> to run the System Setup Utility
