Connecting to a Console Terminal or Modem
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.
For information about cable pinouts, see Cisco Modular Access Router Cable Specifications.
