Checking the Hardware

Check your hardware by:

• Checking the Power
• Checking the Operator Panel Display if available
• Activating Your Display or Terminal

Checking the Power

If the Power-On light on your system is active, go to Checking the Operator Panel Display

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.

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.

If your system became inactive while you were trying to restart the system, go to Restarting the System.

If your system did not become inactive while you were trying to restart the system, go to Checking the Processes.
