Cisco ASR-920-12SZ-IM Hardware Installation Guide

Use the information in the Cisco ASR-920-12SZ-IM Router Specifications table to estimate the power
requirements and heat dissipation of the router based on a given configuration of the router. Determining
power requirements is useful for planning the power distribution system needed to support the router.
Installing the DC Power Supply Module
This equipment is suitable for installation in Network Telecommunications Facilities and locations where the
NEC applies.
This equipment is suitable for installations utilizing the Common Bonding Network (CBN).
The grounding architecture of this product is DC-Isolated (DC-I) for DC-powered products. DC-powered
products have a nominal operating DC voltage of 48 VDC.
Perform the following procedure to install the power supply module:
SUMMARY STEPS
1.
Ensure that the system (earth) ground connection has been made. See the following figure.
2.
If necessary, remove the blank power supply filler plate from the chassis power supply bay opening by
loosening the captive installation screws.
3.
Verify that power to the DC circuit connected to the power supply you are installing is off. To ensure that
power has been removed from the DC circuits, locate the circuit breakers for the DC circuits, switch the
circuit breakers to the OFF position, and tape the circuit-breaker switches in the OFF position.
4.
Grasp the power supply handle with one hand. Place your other hand underneath the power supply. Slide
the power supply into the power supply bay. Make sure that the power supply is fully seated in the bay.
5.
Tighten the captive installation screws of the power supply. The recommended maximum torque is 5.5
in.-lb (0.62 N-m).
