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 adapter cable (RJ-45-to-DB-9, blue)

•One modem adapter cable (RJ-45-to-DB-25, black)

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.

Note For information on identifying rollover cables, see the “Identifying a Rollover Cable” section on page 3-25.

Connecting to the Console Port

To connect a console terminal or a PC running terminal emulation software to the console port on the router, perform the following steps:

Step 1 Use the blue RJ-45-to-DB-9 console adapter cable to connect the router to a terminal. (See Figure 3-24and Figure 3-25.)

For information about cable pinouts, see the online publication Cisco Modular Access Router Cable Specifications, available online and on the Documentation CD-ROM.

Note On Cisco routers, the console port is color-coded blue.

Step 2 Configure your terminal or terminal emulation software for 9600 baud (default), 8 data bits, no parity, and 2 stop bits.

Note Because hardware flow control is not possible on the console port, we do not recommend that

modems be connected to the console port. Modems should always be connected to the auxiliary port.
