Getting Started
Before troubleshooting a software problem, you must connect a terminal or PC to the router using the
light-blue console port. With a connected terminal or PC, you can view status messages from the router
and enter commands to troubleshoot a problem.
You can also remotely access the interface (Ethernet, ADSL, or telephone) by using Telnet. The Telnet
option assumes that the interface is up and running.

should have the following information ready:
Chassis type and serial number
Maintenance agreement or warranty information
