Power-on Self-Test (POST)

When you power-on the server, it performs a series of

tests to check the operation of server components and

some options. This series of tests is called the power-on

self-test, or POST.

POST does the following:

 Checks the operation of some basic system-board

operations

 Checks the memory operation

 Compares the current server configuration with the

stored server configuration information

 Configures PCI adapters

 Starts the video operation

 Verifies that the drives (such as the diskette,

CD-ROM, and hard disk drives) are connected

properly

If Power-On Self-Test is set to [Enhanced], numbers that

show the amount of memory being tested appear in the

top-left corner of the screen until the total amount of

memory in the system is reached. Options for running a

quick POST or accessing the Configuration/Setup Utility

program appear in the lower-left corner of the screen.

Quick mode is the default mode of operation. To change

the mode to [Enhanced], select Start Options from the

Configuration/Setup Utility program menu and follow the

prompts on the screen.

Note

The amount of available memory shown might be

somewhat less than expected because of BIOS

shadowing in RAM.

If POST finishes without detecting any problems, the first

screen of the operating system or application program

appears (if you have not set a power-on password). If you

have set a power-on password, a password prompt

appears. You must enter the password before the first

screen of the operating system or application program will

appear. (For further information on using passwords, see

“System Security” on page 21.)

If Power-On Status is set to [Enabled] and POST detects

a problem, you will hear multiple beeps or no beep. In

most cases, an error code appears in the top left corner of

the screen, and in some cases, a description of the error is

displayed beside the code. (Note that the screen will

sometimes display multiple error codes and descriptions.)

If you hear no beep at all during POST, see

“Symptom-to-FRU Index” on page 105.
