Connecting AC power and ground
When installing media gateways, be aware of the following warnings and cautions.
!
WARNING:
The equipment room alternating current (AC) power and ground wiring must be performed by a
qualified electrician. The AC power circuit must be dedicated to the system. The circuit must not be
shared with other equipment and must not be controlled by a wall switch. The AC receptacle must
not be located under the main distribution frame and must be easily accessible.
CAUTION:
Media gateway grounding must comply with the general rules for grounding contained in
Article 250 of the National Electrical Code (NEC), National Fire Protection Agency
(NFPA) 70, or the applicable electric code in the country of installation. For more
information, see the job aid titled
Approved Grounds

DANGER
:
The latch on the power supply does not remove power from the G650 Media
Gateway. To remove the AC power from the 655A, pull the AC power cord from the
back of the G650 Media Gateway. If there are redundant power supplies, you need to
pull both AC power cords from the back of the G650 Media Gateway. To remove DC
power, first locate and switch the DC circuit breaker to the "off" position and then
disconnect the DC power feed at the back of the G650 Media Gateway.
!
WARNING:
With an G650 Media Gateway if other equipment is installed in the same rack, make sure that the
media gateway does not generate an overcurrent or overload condition. Verify that the customer’s
branch circuit and/or power distribution strip are adequate with respect to overload and overcurrent
protection.
