PA-MC-2T3+ Multi-Channel T3 Port Adapter Installation and Configuration

OL-3526-05

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 “Using

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.
