Powering Down the Router

To power down a Cisco 7200 series router, Cisco 7204VXR or Cisco 7206VXR router, or

Cisco uBR7200 series router, complete the following steps:

Note Before powering down the router, use the copy running-configstartup-configcommand 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 (O) position. Repeat this action if a second power supply is installed in the router.

Note When powering off the router, wait a minimum of 30 seconds before powering it on again.

Step 2 Observe the following items:

•The green OK LED on the power supply turns off.

•The fans stop operating.

•The LEDs on the I/O controller turn off.

•The LEDs on the port adapters turn off.

•On a Cisco uBR7200 series router, the LEDs on the cable interface line cards turn off.

Caution When the power switch on a Cisco uBR7200 series power supply is turned to the off (O) position, the power supply enters a reset cycle for 90 seconds. Wait at least 90 seconds before turning the power switch back to the on () position. If you do not wait the full 90 seconds, the power supply does not restart.

This completes the procedure for powering down the router. For instructions on disconnecting power from the Cisco 7200 series routers, Cisco 7200 VXR routers, or Cisco uBR7200 routers, see the following sections:
