Replacing an AC-Input or DC-Input Power Supply
To replace an AC-input or DC-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. (See

Step 2 Grasp the power supply handle with one hand and place your other hand underneath the
power supply for support. (See Figure 45.)

Step 3
Align the power supply to the power supply bay.
Step 4 Slide the power supply completely into 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 or a 3/16-inch, flat-blade screwdriver.
Note The power supply is not fully seated in the router midplane until you tighten its
captive installation screws.
Step 6 Repeat Step 1 through Step 5 for a second power supply (if present).
Step 7 If there is no second power supply, replace the filler plate on the empty power supply bay.
Using a number 2 Phillips or a 3/16-inch, flat-blade screwdriver, tighten the filler plate’s
captive screws.
