Always use caution and common sense.• Repairs must be performed by qualified service personnel only.• To reduce the risk of electrical shock, do not operate equipment with the cover removed.• Never install network jacks in a wet location unless the jack is designed for that location.• Never touch uninsulated wires or terminals unless the line is disconnected at the network interface.• Never install network wiring during an electrical storm.•
Antistatic Precautions
Electrostatic discharge (ESD) results from the buildup of static electricity and can cause computer
components to fail. Electrostatic discharge occurs when a person whose body contains a static buildup touches
a computer component. This product may contain static-sensitive devices that are easily damaged. Proper
handling, grounding and precautionary ESD measures are essential when installing parts or cards. Keep parts
and cards in antistatic packaging when not in use or during transport. If possible, use antistatic floorpads and
workbench pads.
When handling components, always use an antistatic wrist strap connected to a grounded equipment frame or
chassis. If a wrist strap is not available, periodically touch an unpainted metal surface on the equipment.
Never use a conductive tool, like a screwdriver or a paper clip, to set switches.
