CAUTION: You must ensure the power connections maintain proper polarity. Your power source cables might be labeled
(+) and (-) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the
external DC power source at your site determines how the ARRIS CMTS power cables are connected.
2.
Each supplied cable contains two 10-gauge wires (one red and one white) that must be hard-wired to the DC source by
a qualified service electrician
a.
Connect the red wire to the negative (—) side of the -48V supply.
b.
Connect the white wire to the positive (+) or return side of the -48V supply.
CAUTION: Do not connect the cables to a PM that is not in a chassis.
Be sure to shut off the breaker for the unit and disconnect the -48V DC or 115V AC power cable before removing the PM
from the chassis.
