Setting Up the System 2-21
After a few seconds your system begins the internal Power-On Self Tests
(POST). POST automatically checks the system board, memory board, CPU
module, ECC memory modules, keyboard, mouse, and most installed peripheral
devices. POST also displays the start messages of the BIOS setup utility during
execution.
The POST check results should be checked in the following cases:
!
When the server is being used for the first time.
!
When the server appears to fail.
!
When the server beeps many times between power-on and OS start-up.
!
When an error message appears on the display unit.
Note:
For error messages that appear on the display
unit, refer to subsection POST Error Codes and Messages in
Chapter 5 of this Guide.
!
CAUTION
Always allow POST to complete before powering down your
system.
If you have problems powering on your system, refer to Problem Solving in
Chapter 5 of this User’s Guide.
