Configuring the PA-VXA, PA-VXB, and PA-VXC
To continue your PA-VXA, PA-VXB, or PA-VXC port adapter installation, you must configure the card
type as either T1 or E1 and then configure the interfaces. The instructions that follow apply to all
supported platforms. Minor differences among the platforms—with Cisco IOS software commands—are
noted.

Using the EXEC Command Interpreter
You modify the configuration of your router through the software command interpreter called the EXEC
(also called enable mode). You must enter the privileged level of the EXEC command interpreter with
the enable command before you can use the configure command to configure a new interface or change
the existing configuration of an interface. The system prompts you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>).
At the console terminal, use the following procedure to enter the privileged level:
Step 1
At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a
privileged-level password as follows:
Router> enable
Password:
Step 2
Enter the password (the password is case sensitive). For security purposes, the password is not displayed.
When you enter the correct password, the system displays the privileged-level system prompt (#):
Router#
