Chapter 4 System Startup and Basic System Configuration

Manually Booting the System

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 network environment. For configuration information, see the “Configuring the Router” section on page 4-14.

Note The interface-specific LEDs on the line cards may not power on until you configure the line card interfaces. To verify correct operation of each line card interface, complete the first-time setup procedure and configuration, then check the status of the interfaces against the descriptions in the documentation for each line card.

If the system does not complete each of the preceding steps, go to the “Troubleshooting the Installation” chapter for troubleshooting recommendations and procedures.

Manually Booting the System

If your router does not find a valid system image, or if you interrupt the boot sequence, the system enters ROM monitor mode and displays the ROM monitor prompt (rommon>). From ROM monitor mode, you have access to commands which locate and boot a valid system image.
