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 1-2 for the location of front panel controls
and indicators. See Figure 1-3 for the location of back panel connectors on
the system.)
