Verifying Status of the Redundant Power Supply

Removing and Installing the Cisco AS5400 Power Supply
Caution Do not over torque the terminal block contact screws. The recommended torque is 5.0 in.-lb (0.56 N-m).
a. Insert the safety ground (green wires) into the terminal block ground connectors and tighten the
locking screws. Ensure that no bare wire is exposed.
b. Insert the 48 VDC Return wires into the terminal block positive connectors (+) and tighten the
locking screws. Ensure that no bare wire is exposed.
c. Insert the -48 VDC wires into the terminal block negative connectors (-) and tighten the locking
screws. Ensure that no bare wire is exposed.
d. Make sure that the power supply cords are secured to the cable strain-relief clamps on the DC power
supply with cable ties.
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. To see translations of
the warnings that appear in this publication, refer to the Regulatory Compliance and Safety
Information document that accompanied this device.
Note You can order a Y-connector (CAB-AC-Y) to plug into both power connectors in the power
supply. If you use this Y-connector, you will remove the backup feature of this power supply by
eliminating redundant operations and reducing reliability. Cisco highly recommends that you
use both power cords whenever possible.
Step 8 Power ON the universal gateway.
The internal power supply fan should power on. If you are using a redundant power supply, the six green
LEDs on the front of the power supply should light. If one LED is not lit, consult the appropriate
redundant power supply software message to determine where the problem is located.
