Precautions
The CAUTION, WARNING, and DANGER statements that appear throughout this manual are
intended to provide critical information for the safety of both the service engineer and operator, and
enhance equipment reliability. The definitions and symbols for such statements comply with ANSI
Z535.2, American National Standard for Environmental and Facility Safety Signs, and ANSI
Z535.4, Product Safety Signs and Labels, issued by the American National Standards Institute.

Safety Guidelines
Under proper conditions, this unit will operate reliably and safely in your network. If any
component is improperly handled or installed, equipment failure or personnel hazard may occur.
Use caution and common sense when installing network wires. Use the following guidelines,
especially when unsafe conditions exist or when potentially hazardous voltages are present:
•
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 network wires or terminals unless the network 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. ESD occurs when a person whose body contains a static buildup touches a
computer component. This product card may contain static-sensitive components that are easily
damaged. Proper handling, grounding and precautionary ESD measures are essential. Keep parts
and cards in antistatic packaging during transport or when not in use. When handling always use
antistatic floorpads, workbench pads and 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 screw driver or paper clip to set switches.
