14 280-Watt AC-Input Power Supply Replacement Instructions

Removing and Replacing the AC-Input Power Supply

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 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 (use a number 2 Phillips or a 3/16-inch, ﬂat-blade

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.

Reconnecting Input Power and Turning On the Power Supply

The following procedures explain how to reconnect AC-input power to Cisco 7200 series routers,

turn on the power supply, and verify the power supply is operating properly.

To reconnect AC-input power to Cisco 7200 series routers complete the following steps:

Step 1 At the rear of the router, check that the power switch on the power supply is in the OFF

(O) position.

Step 2 Slide the cable-retention clip up, away from the AC receptacle, and plug in the power

cable.

Step 3 Secure the cable in the power supply AC receptacle by sliding the cable-retention clip

down until it snaps around the connector. The cable-retention clip provides strain relief

for the AC power cable. (See Figure 6.)
