Power On Self Test (POST)
Each time you turn on the system, POST starts running. POST checks the server board, processor,
memory, keyboard, and most installed peripheral devices. During the memory test, POST displays
the amount of memory that it is able to access and test. The length of time needed to test memory
depends on the amount of memory installed. POST is stored in flash memory.
1. Turn on your video monitor and server. After a few seconds POST begins to run.
2. After the memory test, these screen prompts and messages appear until POST completes or
until the user presses F2:
Press <F2> key if you want to run SETUP
Keyboard.....Detected
Mouse........Detected
3. During peripheral device detection, the following message appears:
Press <Ctrl><A> to enter SCSI Utility
4. Press <Ctrl+A> if there are SCSI devices installed. When the utility opens, follow the
displayed instructions to configure the onboard SCSI host adapter settings and to run the
SCSI utilities. Also see “Using the Adaptec SCSI Utility” on page 99. If you do not enter the
SCSI utility, the boot process continues.
5. Press <Esc> during POST to pop up a boot menu when POST finishes. From this menu you
can choose the boot device or enter BIOS Setup.
After POST completes, the system beeps once.
What appears on the screen after this depends on whether you have an operating system loaded and
if so, which one.
If the system halts before POST completes running, it emits a beep code indicating a fatal system
error that requires immediate attention. If POST can display a message on the video display screen,
it causes the speaker to beep twice as the message appears.
Note the screen display and write down the beep code you hear; this information is useful for your
service representative. For a listing of beep codes and error messages that POST can generate, see
the “Solving Problems” chapter in this manual.
