Powering Down the Router and Disconnecting Input Power
To power down a Cisco 7200 series router that has an installed AC-input power supply, complete the

Note Before powering down the router, use the copy running-config startup-config command to
save the router’s running configuration to nonvolatile memory.
Step 1 Facing the rear of the router, place the power switch (on the power supply) in the OFF (0)
position. Repeat this action if a second power supply is installed in the router.
Step 2 Observe the following items:
• The green OK LED on the power supply turns off

Step 2 Push down on the cable-retention clip that secures the input power cable to the router’s

Step 3 Unplug the other end of the input power cable from the power supply (refer to Figure 10).
