WARNING! When the workstation is plugged into an AC power source, voltage is always applied to the system board. To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect the power cord from the wall outlet and allow the internal system components to cool before touching.
Look for the LED on the system board. If the LED is illuminated, the system still has power. Power off the workstation and remove the power cord before proceeding.
