Step 3 Using a 3/16-inch flat-blade screwdriver, loosen the screws that secure the router to the front mounting
strips of the rack.
Step 4 Position at least one person in front of the rack to support the front underside of the router.
Step 5 From the rear of the rack, carefully push the front of the router out of the rack until there is enough
clearance to remove the power supply.
Step 6 Grasp the power supply handle and pull the power supply from the router.
Caution To maintain agency compliance requirements and meet EMI emissions standards for the Cisco 7200
series chassis 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.
Step 7 Repeat Step 1 through Step 6 for the other installed power supply (if present).
This completes the procedure for removing an AC-input or DC-input power supply from a Cisco 7200
series router.
