Hardware check

There are several procedures you can use to check your hardware.

Check your hardware by:

Checking the power:

If the Power-On light on your system is active, go to Checking the operator panel display, below.

If the Power-On light on your system is not active, check that the power is on and the system is plugged in.

Checking the operator panel display:

If your system has an operator panel display, check it for any messages.

If the operator panel display on your system is blank, go to Activating your display or terminal, below.

If the operator panel display on your system is not blank, go to the service guide for your unit to find information concerning digits in the Operator Panel Display.

Activating your display or terminal:

Check several parts of your display or terminal, as follows:

• Make sure the display cable is securely attached to the display and to the system unit.
• Make sure the keyboard cable is securely attached.
• Make sure the mouse cable is securely attached.
• Make sure the display is turned on and that its Power-On light is lit.
• Adjust the brightness control on the display.
• Make sure the terminal's communication settings are correct.

If your system is now active, your hardware checks have corrected the problem.
