Connection Procedures and Precautions

Connect each WAN and LAN cable to the appropriate connector on the chassis or interface card.

•Position the cables carefully, so that they do not put strain on the connectors.

•Organize the cables in bundles so that cables do not intertwine.

•Inspect the cables to make sure that the routing and bend radiuses are satisfactory. Reposition the cables, if necessary.

•Install cable ties in accordance with your site requirements.

For cable pinouts, see Cisco Modular Access Router Cable Specifications.

Connecting to a Console Terminal or Modem

Your router has asynchronous serial console and auxiliary ports. These ports provide administrative access to your router either locally (with a console terminal or PC) or remotely (with a modem).

Cisco provides the following cables and adapters for connecting your router to a console terminal, PC, or modem:

•One console cable (RJ-45-to-DB-9, blue)

•One modem adapter (DB-9-to-DB-25)

This section describes how to connect a console terminal or PC to the console port and how to connect a modem to the auxiliary port.
