Safety Information
This manual should be read in its entirety and all procedures completely understood before
installing or operating the unit, including all notes, cautions and warnings (examples below). 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.
These statements also enhance equipment reliability. The following definitions and symbols for
CAUTION, WARNING, and DANGER as they are used 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
•
Always use caution and common sense, especially when unsafe conditions or 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 telephone jacks in a wet location unless the jack is designed for that location.
•
Never touch uninsulated telephone wires or terminals unless the telephone line is
disconnected at the network interface.
•
Never install telephone wiring during an electrical storm.
Antistatic Precautions
This product may contain static-sensitive devices that are easily damaged by ESD (electrostatic
discharge). ESD occurs when a person whose body has built up static electricity touches a computer
component. ESD can cause computer components to fail. Take proper handling, grounding and
precautionary ESD measures when installing parts or cards. Keep parts and cards in antistatic
packaging when not in use or during transport. If possible, use antistatic pads on floor and
workbench. 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.
Note

A note is typically used as a suggestion.
Important
Indicates an emphasized note. It is something you should be particularly aware of; something not readily
apparent. Important is typically used to prevent equipment damage.
CAUTION
indicates conditions or practices that can cause damage to equipment or loss of
data.
WARNING
indicates an imminently hazardous situation which, if not avoided, may result
in minor to moderate injury. It may also be used to alert against unsafe practices.
