Making Cable Connections to the RSP
This section describes how to make cable connections to the console and auxiliary ports on the RSPs in
the Cisco 7500 series routers. (Specific differences between RSPs are clearly noted.)
Note Pinouts for the console and auxiliary ports and cables are listed in the
Ports—Console and Auxiliary" section on page

Connecting a Console Terminal to the RSP

The system console port on the RSP is a DB-25 receptacle DCE port for connecting a data terminal,
which will allow you to configure and communicate with your system. Use the console cable provided
to connect the terminal to the console port on the RSP. The console port is located on the RSP next to
the auxiliary port, as shown in
oriented horizontally.)
Before connecting the console port, check your terminal's documentation to determine the baud rate of
the terminal you will be using. The baud rate of the terminal must match the default baud rate (9600
baud). Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits (9600,8N2).

Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports
Note
must be capable of asynchronous transmission. (Asynchronous devices are the most common type of
serial devices; for example, most modems are asynchronous devices.)

Connecting to the Auxiliary Port

The auxiliary port on the RSP is a DB-25 plug DTE port for connecting a modem or other DCE device
(such as a CSU/DSU or another router) to the router. The port is located next to the console port on the
RSP and is labeled AUX. An example of a modem connection is shown in
