Removing and Replacing an AC-Input Power Supply
Installing the AC-Input Power Supply and Connecting AC-Input Power
To install an AC-input power supply in a Cisco 7200 series router, complete the following steps:
Step 1 Make sure the power switch on the power supply is in the OFF (0) position.
Step 2 Grasp the power supply handle with one hand and place your other hand underneath the
power supply for support (refer to Figure 8).
Step 3 Align the power supply to the power supply bay.
Step 4 Slide the power supply completely in to the power supply bay until its faceplate is flush
with the router’s rear panel.
Caution When inserting a power supply into the router, do not use unnecessary force; slamming
the power supply into the bay can damage the connectors on the rear of the supply and on the
midplane.
Step 5 Seat the power supply in the router by tightening its captive screws with a number 2
Phillips screwdriver.
Note The power supply is not fully seated in the router midplane until you tighten its captive
installation screws (use a number 2 Phillips screwdriver).
Step 6 If you pushed the router forward in the rack, slowly guide the router back into the rack.
Step 7 Use a 3/16-inch flat-blade screwdriver to tighten the screws that secure the router to front
mounting strips of the rack.
This completes the procedures for replacing a power supply in the router. Proceed to the following
section “Reconnecting Input Power and Turning On the Power Supply.”
