If the ROM monitor prompt (rommon>) appears on the system console, your router
did not find a valid system image, or the boot sequence was otherwise interrupted,
and the system entered read-only memory (ROM) monitor mode.
To boot a Cisco IOS software image manually, enter the boot command on the
system console. For information on using the various forms of the boot command,
see the following sections:
• Locating a Valid Cisco IOS Software Image, page 3-47
• Booting from the Cisco IOS Software Image, page 3-48
System Configuration Dialogue
The following information is an example of a System Configuration Dialog
interactive script message that appears on the system console. This interactive
script prompts you through the steps to create a router configuration database file
defining basic system operation parameters.

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. For configuration information, see the “Router
Configuration” section on page 3-49.
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, see Chapter 4,
“Troubleshooting the Installation.”
