the EXEC Command Interpreter" section on page 4-1
At the privileged-level prompt, enter configuration mode and specify that the console terminal is the

Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

The following example is for a PA-MC-2T3+ in port adapter slot 6 of a Cisco 7200 series router.

Router# show controller T3 6/0
T3 6/0 is administratively down.
Router# show controller T3 6/1
T3 6/1 is administratively down.

The example that follows is for a port adapter on a VIP in interface processor slot 1 of the Cisco
7500 series router:
Router(config)# controller T3 1/0/0
Router(config-controller)# shutdown
Router(config)# controller T3 1/0/1
Router(config-controller)# shutdown
The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:
Router(config)# controller T3 1/0
Router(config-controller)# shutdown
Router(config)# controller T3 1/1
Router(config-controller)# shutdown
Both T3 ports of the PA-MC-2T3+ should be shut down before removing the port adapter.
