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
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.
■ The cores in the mains lead are colored in accordance with the following code
(within the United States):
■ Green and yellow—Earth
■ Blue—Neutral
■ Brown—Live
■ When a router is equipped with two AC power supplies, both power cords (one
for each power supply) must be unplugged to completely disconnect power to
the router.
■ Note the following warnings printed on the AC power supply faceplate:
■ To completely de-energize the system disconnect maximum of 2 power
cordsets.
■ Apparaten skall anslutas till jordat uttag när den ansluts till ett nätverk.
