Removing and Installing the Cisco AS5350 Power Supply
Figure 38 Connecting DC Power Supply—Redundant Power Supply
Note This product is intended for installation in restricted access areas and is approved for connection
using 12 or 14 AWG copper conductors only. The installation must comply with all applicable
codes.
a. Strip off a quarter of an inch (1/4 in. [0.625 cm]) of insulation on the safety ground, +48 VDC, and
-48 VDC input wires.
Note For central office installations, it is recommended to use a 6 AWG green ground wire with one
end connected to reliable earth. The other end of the wire should be crimped onto the
double-hole lug provided in the installation pack. The lug should be secured to the mating holes
on the side of the chassis with the two screws included in the accessory pack.
Note If you are installing a redundant power supply, you should attach appropriate sized spade
terminals to the stripped ends of the ground and input wires.
b. Insert the safety ground (green wires) into the DC connector ground connectors and tighten the
locking screws. Ensure that no bare wire is exposed.
c. Insert the 48 VDC Return wires into the DC connector positive connectors (+) and tighten the
locking screws. Ensure that no bare wire is exposed.
d. Insert the -48 VDC wires into the DC connector negative connectors (-) and tighten the locking
screws. Ensure that no bare wire is exposed.
e. Make sure that the power supply wires are secured to cable strain-relief clamps with cable ties.
