• 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.
