Cisco Systems RSP8 manual Connecting a Console Terminal, Connecting to the Auxiliary Port

Installing the RSP8

Connecting a Console Terminal

The system console port on the RSP8 is a DB-25 receptacle DCE port for connecting a console terminal, which you need to configure in order to communicate with your system. The console port is located on the RSP8 just below the auxiliary port, as shown in Figure 5, and is labeled Console.

Before connecting the console port, check the documentation for your terminal to determine the baud rate of the terminal you are 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).

Use the console cable provided to connect the terminal to the console port on the RSP8, and then follow the steps in the “Restarting the System” section on page 21 .

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

Connecting to the Auxiliary Port

The auxiliary port on the RSP8 is a DB-25 plug DTE port for connecting a modem or other DCE device (such as a channel service unit [CSU], data service unit [DSU], or other router) to the router. The port is located next to the console port on the RSP8 and is labeled AUX. An example of a modem connection is shown in Figure 5.

Using the Y-Cables for Console and Auxiliary Connections

For systems with two RSP8s installed and the HSA or the HA feature enabled, you can connect to either the console or auxiliary ports simultaneously on both RSPs using a special, optional Y-cable. If only one RSP8 is installed, it is the system active by default.
