application program will appear. (For further information on using

Utility Program” on page 17.)
If Power On Status is 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.) For more information about what caused an error
message to appear and what action to take, refer to “Solving POST
error message problems” on page 152 and “POST message charts”
on page 156.
If you hear no beep at all during POST, refer to “Troubleshooting
charts” on page 181. You might need to have your server serviced.
Types of error messages
Error messages that appear on the screen might be text, numeric, or
both. There are several types of error messages:
POST error messages
These messages appear when POST finds problems with the
hardware during startup or when a change in the hardware
configuration is found. POST error messages are 3-, 4-, 5-, 8-, or
12-character alphanumeric messages and include brief explanations
(except I999XXXX errors).
For more information about what caused an error message to
appear and what action to take, refer to “Solving POST error
message problems” on page 152 and “POST message charts” on
page 156.
SCSI error messages
These messages appear if a problem or conflict is detected by the
Adaptec SCSI subsystem.
