Introduction to Troubleshooting

This chapter provides information about isolating a failing/failed component in a Model
743 board computer through the use of diagnostic tests and trouble shooting techniques. A
failed component is traced to the level of the Field Replaceable Unit(FRU) and the FRU is
replaced to correct a problem.

To troubleshoot a 743 you must be familiar with the HP-UX operating system and be able
to start and stop processes. You should familiarize yourself with the various diagnostic
software available and understand what the test results indicate.

Diagnostic Overview

Three types of diagnostics are available for the Model 743:

•

Selftests are part of the Boot ROM code. They initialize and test the functional ar-
eas needed to boot the operating system.

•

Offline diagnostics are on the Support Tape, a separate tape or CD-ROM media.
They are ISL based.

•

Online diagnostics are supplied with the operating system, but require the operat-
ing system to be booted.
