Juniper Networks J-series Services Router J2320 - Manual (Page 275)

■ Install the Services Router in compliance with the following local, national, or
international electrical codes:
■ United States—National Fire Protection Association (NFPA 70), United States
National Electrical Code.
■ Canada—Canadian Electrical Code, Part 1, CSA C22.1.
■ Other countries—International Electromechanical Commission (IEC) 60364,
Part 1 through Part 7.
■ Evaluated to the TN power system.
■ Locate the emergency power-off switch for the room in which you are working
so that if an electrical accident occurs, you can quickly turn off the power.
■ Make sure that grounding surfaces are cleaned and brought to a bright finish
before grounding connections can be made.
■ Do not work alone if potentially hazardous conditions exist anywhere in your
workspace.
■ Never assume that power is disconnected from a circuit. Always check the circuit
before starting to work.
■ Carefully look for possible hazards in your work area, such as moist floors,
ungrounded power extension cords, and missing safety grounds.
■ Operate the Services Router within marked electrical ratings and product usage
instructions.
■ For the Services Router and peripheral equipment to function safely and correctly,
use the cables and connectors specified for the attached peripheral equipment,
and make certain they are in good condition.
Many Services Router components can be removed and replaced without powering
down or disconnecting power to the Services Router, as detailed in elsewhere in this
manual. Never install equipment if it appears damaged.
AC Power Electrical Safety Guidelines
CAUTION: For routers with AC power supplies, an external surge protective device
(SPD) must be used at the AC power source.
The following electrical safety guidelines apply to AC-powered routers:
■ AC-powered routers are shipped with a three-wire electrical cord with a
grounding-type plug that fits only a grounding-type power outlet. Do not
circumvent this safety feature. Equipment grounding should comply with local
and national electrical codes.
■ You must provide an external Listed circuit breaker rated minimum 15 A in the
building installation.
■ The power cord serves as the main disconnecting device. The socket outlet must
be near the router and be easily accessible.
