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

DETAILED STEPS
Step 1
Ensure that the system (earth) ground connection has been made. See the following figure.
Step 2
If necessary, remove the blank power supply filler plate from the chassis power supply bay opening by loosening the
captive installation screws.
Step 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.
Step 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.
Step 5
Tighten the captive installation screws of the power supply. The recommended maximum torque is 5.5 in.-lb (0.62 N-m).
