Chapter 3 Installing a Cisco 7500 Series Router

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 “RSP Asynchronous Serial

Ports—Console and Auxiliary” section on page 1-44.

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 Figure 3-22, and is labeled Console. (The RSP in the Cisco 7505 is

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).

Figure 3-22 Console and Auxiliary Port Connections (All RSPs)

Note Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports

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 Figure 3-22.
