Be aware of and avoid contact with areas subject to high voltage or amperage. Because some components can
store dangerous charges even after power is disconnected, always discharge components before touching.
Never insert objects of any kind through openings in the equipment. Conductive foreign objects could produce a
short circuit that could cause fire, electrical shock, or equipment damage.
Remove rings, watches, and other metallic objects from your body before opening equipment. These could be
electrical shock or burn hazards.
Ensure that a proper electrostatic discharge device is used, to prevent damage to electronic components.
Do not attempt internal service of equipment unless another person, capable of rendering aid and resuscitation, is
present.
Do not work near rotating fans unless absolutely necessary. Exercise caution to prevent fans from taking in
foreign objects, including hair, clothing, and loose objects.
Use care when moving equipment, especially rack-mounted modules, which could become unstable. Certain
items may be heavy. Use proper care when lifting.
