Chapter 5 Troubleshooting the System Hardware

Identifying System Problems

Step 3 Set all display controls on the terminal or display device to the middle position. Step 4 Power up all external devices.

Step 5 Power up the device.

Step 6 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.

Step 7 Check the system error LED on the front panel (see Figure 1-2); if it is on, see the “System Error LED and the Diagnostic Panel LEDs” section on page 5-33.

Step 8 Check the system error log. If an error was recorded by the system, see the “Symptoms and Solutions” section on page 5-28.

Step 9 Start the diagnostic programs and check for the following responses:

One beep

Readable instructions or the main menu

Step 10 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 page 5-28.

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 all the switches, controls, and cable connections can easily solve these problems. (See Figure 1-2for the location of front panel controls and indicators. See Figure 1-3for the location of back panel connectors on

the system.)
