Diagnostic Procedures

This section provides a more detailed approach to diagnosing and identifying problems
and then locating their sources.

Error Checking

Each time you turn on the system, POST (Power-On-Self-Test) runs automatically and
checks the baseboard, processors, memory board, keyboard, and mouse.
If POST finds an error, it displays an error message. Refer to the Error Message section
in this chapter for an explanation of each error message.

Troubleshooting Guide

Use the following troubleshooting procedures to help you identify a problem. These
general procedures lead you through the following:
!
Monitoring POST while it is running
!
Verifying proper operation of key system LEDs
!
Confirming loading of the operating system.

Monitoring POST

Each time you turn on the system, the Power-On Self-Test (POST) runs automatically
and checks the carriers, processors, memory, keyboard, mouse, and most installed
peripheral devices.
During the memory test, POST displays the amount of memory that it is able to access
and test. Depending on the amount of memory, it may take several minutes to complete
the memory test. When the memory test completes, the following is displayed:
Press <F2> to enter SETUP
Press <F2> to enter BIOS SETUP. When the utility appears, follow the instructions on
your monitor to configure BIOS. See chapter 3, "Configuring Your System." If you do
not press <F2>, the above message remains for a few seconds and the boot process
continues, and the system beeps once. Then this message appears:
Operating System not found
If you do not press <F2>, the boot process continues and this message appears:
Press <Ctrl> <C> to enter SCSI Utility
Press <Ctrl+C> if you want to configure SCSI devices in your system. When the utility
appears, follow the instructions on your monitor to configure the SCSI host adapter
settings and run the SCSI disk utilities. See chapter3, Configuring Your System. If you
choose not to run SCSI Utility, the boot process continues.
Press <Esc> during POST to access a boot menu when POST finishes. From this
menu, you can choose the boot device or enter BIOS Setup.
