Chapter 3 Installing the Cisco AS5400XM Universal Gateway
Where to Go Next
Caution In a DC power supply installation do not connect the 48 VDC Return to chassis ground at the
Cisco AS5400XM universal gateway. A single-point ground is recommended at the power distribution
rack.
Step 2 Strip off 1/4 in. (0.625 cm) of insulation on the safety ground, 48 VDC Return, and –48 VDC input
wires.
Step 3 Insert the safety grounds (green wire) into the terminal block ground connectors and tighten the locking
screws. Ensure that no bare wire is exposed.
Note For central office installations, we recommend using a copper 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 either side of the
chassis with the two screws included in the accessory pack.
Caution Do not overtorque the terminal block contact screws. The recommended torque is 5.0 in.-lb (0.56 N-m).
Step 4 Insert both 48 VDC Return wires into the terminal block positive connectors (+) and tighten the locking
screws. Ensure that no bare wire is exposed.
Step 5 Insert both –48 VDC wires into the terminal block negative connectors (–) and tighten the locking
screws. Ensure that no bare wire is exposed.
Step 6 Secure the power supply cords to the cable strain-relief clamps on the DC power supply with cable ties.
(See
Figure 3-15 .)
Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and
reinstate power by moving the handle of the circuit breaker to the ON position. Statement 8
