Cisco Systems XR 12406 manual External Network Interface, Manually Booting the System

Chapter 3 Installing the Cisco XR 12406 Router

External Network Interface

If the router does not power on, or if any interfaces do not initialize properly, see Chapter 4, “Troubleshooting the Installation”. If you are still unable to resolve the problem, contact your Cisco service representative for assistance.

External Network Interface

After configuration, the RP and line cards can communicate with external networks.

You do not need to configure the network interfaces immediately, but you cannot connect to a network until you configure the interfaces for operation in your networking environment.

Note The interface-specific LEDs on the line cards go on when the line card interfaces are configured.

To verify correct operation of each line card interface, complete the first-time setup procedures and configuration, then check the status of the interfaces against the LED descriptions in the configuration notes for each line card.

If the system does not complete each of the boot process steps, go to Chapter 4, “Troubleshooting the Installation”.

Manually Booting the System

If your router does not find a valid system configuration image, or if you interrupt the boot sequence, the system might enter read-only memory (ROM) monitor mode and display the ROM monitor prompt (rommon>). From ROM monitor mode, you have access to a number of commands to locate and boot a valid system image.

Boot Process Overview

The example below assumes that the router is plugged into a power source and the router is running, blower module fans are audible, and alarm card ENABLED LEDs are lit up.
