Chapter 2 Preparing for Installation
Safety Guidelines
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during
normal use.
Warning When installing the unit, the ground connection must always be made first and disconnected last.
• Do not work alone if potentially hazardous conditions exist.
• Never assume that power is disconnected from a circuit. Always check.
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
– Use caution; do not become a victim yourself.
– Turn off power to the system.
– If possible, send another person to get medical aid. Otherwise, assess the condition of the victim
and then call for help.
– Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that
a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the
phase conductors (all current-carrying conductors).
In addition, use the guidelines that follow when working with any equipment that is disconnected from
a power source, but still connected to telephone wiring or other network cabling.
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
• Use caution when installing or modifying telephone lines.
Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
Electrostatic Discharge Prevention
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage
occurs when electronic components are improperly handled and can result in complete or intermittent
failures. Figure 2-1 illustrates how to attach an electrostatic discharge wrist strap.
Always follow ESD-prevention procedures when you remove and replace components. Ensure that the
chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it
makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to
