Chapter5 Troubleshooting the System Hardware
Identifying System Problems
Step3 Set all display controls on the terminal or display device to the middle position.
Step4 Power up all external devices.
Step5 Power up the device.
Step6 Record any POST error messages that are displayed on the screen. If an error is
displayed, look up the first error in the “POST Error Codes” section on page 5-52.
Step7 Check the system error LED on the front panel (see Figure1-2); if it is on, see the
“System Error LED and the Diagnostic Panel LEDs” section on page 5-33.
Step8 Check the system error log. If an error was recorded by the system, see the
“Symptoms and Solutions” section on page5-28.
Step9 Start the diagnostic programs and check for the following responses:
•One beep
•Readable instructions or the main menu
Step10 Take one of the following actions:
•If you received both responses, run the diagnostic programs. For information
on how to use the diagnostic programs, see the “Using the System Diagnostic
Programs” section on page 5-5.
If the diagnostic programs were completed successfully and you still suspect
a problem, see the “Undetermined Problems” section on page 5-25.
•If you did not receive both responses, find the failure symptom in the
“Symptoms and Solutions” section on page5-28.
Checking Connections and Switches
Improperly set switches and controls and loose or improperly connected cables
are the most likely source of problems for the chassis or other external equipment.
A quick check of allthe switches, controls, and cable connections can easily
solve these problems. (See Figure 1-2 for the location of front panel controls
and indicators. See Figure 1-3 for the location of back panel connectors on
the system.)
