Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+
Using the EXEC Command Interpreter
Replacing an Existing Port Adapter
Before you remove or replace a port adapter, use the
shutdown
command to disable the port adapter to
prevent anomalies when you remove and reinstall the port adapter. When you shut down an interface, it
is designated
administratively down
in the
show
command displays.
Follow these steps to shut down an interface:
Step 1
Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the
the EXEC Command Interpreter” section on page 5-1
for instructions.)
Step 2
At the privileged-level prompt, enter configuration mode and specify that the console terminal is the
source of the configuration subcommands, as follows:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Shutting Down the T3 Controller
Step 3
Shut down the T3 controller on the PA-MC-2T3+ with the controller command:
shutdown
This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with
the
no shutdown
controller command.
Examples follow:
•
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
Note
Both T3 ports of the PA-MC-2T3+ should be shut down before removing the port adapter.
Step 4
Verify that the two T3 ports are now shut down using the
show controller T3
command shown in the following examples:
The following example is for a PA-MC-2T3+ in port adapter slot 6 of a Cisco 7200 series router.
Router(config-controller)#
end
Router#
show controller T3 6/0
T3 6/0 is administratively down.
Router#
show controller T3 6/1
T3 6/1 is administratively down.
