Identifying System Problems

To identify system problems, follow these steps:

Step 1 Check the power LED.

Step 2 Power down the device and all external devices.

Step 3 Check all cables and power cords. (See the “Checking Connections and Switches” section on page 5-2.)

Step 4 Set all display controls on the terminal or display device to the middle position.

Step 5 Power up all external devices.

Step 6 Power up the device.

Step 7 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 5-4.

Step 8 If the diagnostic programs were completed successfully and you still suspect a problem, see the

“Troubleshooting Undetermined Problems” section on page 5-12.

Step 9 Check the system error log to see if an error was recorded by the system.

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 1-1 for the location of front panel

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

To check all the connections and switches, follow these steps:

Step 1 Power down the system, including any attached peripherals such as external drives. Disconnect all the

power cables from their electrical outlets.

Step 2 If the system is connected to a power strip (or power distribution unit), turn the power strip off and then

on again.

Is the power strip receiving power?

Ye s . Go to Step 5.

No. Go to Step 3.

Step 3 Plug the power strip into another electrical outlet.

Is the power strip receiving power?

Ye s . The original electrical outlet probably does not function. Use a different electrical outlet.

No. Go to Step 4.

Step 4 Plug a system that you know works into the electrical outlet.

Does the system receive power?

Ye s . The power strip is probably not functioning properly. Use another power strip.

No. Go to Step 5.
