2.1 Power-On

Self-Test

(POST)

POST is a series of diagnostic tests that runs automatically when the system is turned on. POST
checks the following items to ensure that the computer system is functioning properly:

Keyboard

Memory modules

All mass storage devices

Processors

Controllers

If the Power-On Password is set, a key icon appears on the screen while POST is running. You
will need to enter the password before continuing. Refer to

Section 3.1, “Initial Configuration

and Deployment”

for information on setting, deleting, or bypassing the password.

If POST finds an error in the system, an audible and/or visual message occurs. For POST error
messages and their solutions refer to

Appendix C, “POST Error Messages.”
