WARNING! To reduce the risk of personal injury from electric shock, hot surfaces, or re:
Disconnect the power cord from the AC outlet before removing the enclosure. Energized parts are inside.
Allow the internal system components to cool before you touch them.
Replace and secure the enclosure before restoring power to the equipment.

Plug the power cord in a grounded (earthed) AC outlet that is easily accessible at all times.
For your safety, do not place anything on power cords or cables. Arrange them so that no one can accidentally
step on or trip over them. Do not pull on a cord or cable. When unplugging from the AC outlet, grasp the cord
by the plug.
To reduce the risk of serious injury, read the Safety & Comfort Guide. It describes proper workstation setup
and provides guidelines for posture and work habits that increase your comfort and decrease your risk of
injury. It also provides electrical and mechanical safety information. This guide is located on the web at

IMPORTANT: Static electricity can damage the electrical components of the computer or optional
equipment. Before beginning these procedures, be sure that you are discharged of static electricity by briey
touching a grounded metal object.

must disconnect the power cord from the power source and wait 30 seconds before opening the computer to
prevent damage to internal components.
