Chapter 3 Installing the Cisco XR 12406 Router

Connecting to the Console and Auxiliary Ports

Note The console and auxiliary ports are both 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.

PRP Console Port Signals

The console port on the PRP is a DCE RJ-45 receptacle. Table 3-1 lists the signal-to-pin correspondence for the PRP console port.

1. These pins are not connected.

PRP Auxiliary Port Signals

The auxiliary port on the PRP is a DTE, RJ-45 plug for connecting a modem or other DCE device (such as a CSU/DSU or another router) to the router. The port is labeled AUX, as shown in Figure 3-8. The asynchronous auxiliary port supports hardware flow control and modem control. Table 3-2 lists the signal-to-pin correspondence for the PRP auxiliary port.
