• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a
microscope to determine if damage has occurred.

Connecting a Console to the Router
Before you create a network management connection for the router or connect the router to the network, you
must create a local management connection through a console terminal and configure an IP address for the
router. The router can be accessed using remote management protocols, such as SSH and Telnet. By default,
SSH is included in the software image. But telnet is not part of the software image. You must manually install
the telnet optional package to use it.
You also can use the console to perform the following functions, each of which can be performed through
the management interface after you make that connection:
• configure the router using the command-line interface (CLI)
• monitor network statistics and errors
• configure Simple Network Management Protocol (SNMP) agent parameters
• initiate software download updates via console
You make this local management connection between the asynchronous serial port on a console device capable
of asynchronous transmission. Typically, you can use a computer terminal as the console device.
Before you can connect the console port to a computer terminal, make sure that the computer terminal supports
VT100 terminal emulation. The terminal emulation software makes communication between the router and
computer possible during setup and configuration.
Note
Before you begin
• The router must be fully installed in its rack. The router must be connected to a power source and grounded.
• The necessary cabling for the console, management, and network connections must be available.
• An RJ45 rollover cable and a DB9F/RJ45 adapter.
• Network cabling should already be routed to the location of the installed router.
