280-Watt AC-Input Power Supply Replacement Instructions 9

Single Power Supply Configuration

Figure 3 Captive Installation Screws and Handle on the AC-Input Power Supply

If the router is not installed in a standard 19-inch, 4-post or telco rack, skip to Step 5. If

the router is installed in a rack, determine if any permanent rack ﬁxtures, such as a power

strip, are obstructing access to the power supply. If a rack ﬁxture is obstructing access to

the power supply, proceed to Step 2.

Step 2 Using a 3/16-inch ﬂat-blade screwdriver, loosen the screws that secure the router to the

front mounting strips of the rack.

Step 3 Position at least one person in front of the rack to support the front underside of the router.

Step 4 From the rear of the rack, carefully push the router out of the front of the rack until there

is enough clearance to remove the power supply.

Step 5 Grasp the power supply handle and pull the AC-input power supply from the router.

Caution To maintain agency compliance requirements and meet EMI emissions standards for

Cisco 7200 series routers with a single power supply, the power supply ﬁller plate must remain in

the power supply adjacent to the installed power supply. Do not remove this ﬁller plate from the

router unless you intend to install a redundant power supply.

This completes the procedure for removing the AC-input power supply from Cisco 7200 series

routers.

Replacing the AC-Input Power Supply and Connecting Power

To install a new AC-input power supply in a Cisco 7200 series chassis, complete the following steps:

Step 1 Make sure the power switch on the power supply is in the OFF (O) position.

Step 2 Grasp the power supply handle with one hand and place your other hand underneath the

power supply for support. (See Figure 4.)
