Configuring a Cisco 7401ASR Router

Step 5 When you start up the router for the first time, the system automatically enters the setup facility, which determines which port adapter is installed and prompts you for configuration information. On the console terminal, after the system displays the system banner and hardware configuration, you will see the following System Configuration Dialog prompt:

--- System Configuration Dialog ---

At any point you may enter a questions mark ‘?’ for help.

Use ctrl-c to abort configuration dialog at any prompt.

Default settings are in square brackets ‘[]’.

continue with configuration dialog? [yes]:

You have the option of proceeding with the setup facility to configure the interfaces, or exiting from setup and using configuration commands to configure global (system-wide) and interface-specific parameters. You do not have to configure the interfaces immediately; however, you cannot enable the interfaces or connect them to any networks until you have configured them.

Many of the port adapter LEDs do not go on until you have configured the interfaces. To verify correct operation of each interface, complete the first-time startup procedures and configuration, and then refer to the configuration note for the port adapter for LED descriptions and to check the status of the interfaces.

If the system does not complete each of the steps in the startup procedure, proceed to Chapter 5, “Troubleshooting,” for troubleshooting recommendations and procedures.
