Cisco ASR 9001 Hardware Installation Guide

• Auxiliary port—RJ-45 interface for connecting a modem.
The console and auxiliary ports are asynchronous serial ports. Ensure that devices connected to these ports
are capable of asynchronous transmission.
Note
Console Port Signals
The RP console port is an RJ-45 interface for connecting a terminal to the router. The console port does not
support modem control or hardware flow control and requires a straight-through RJ-45 cable.
Before connecting a terminal to the console port, check the terminal setting for the data transmission rate, in
bits per second (bps). The terminal transmission rate setting must match the default rate of the RP console
port, which is 115200 bps. Set the terminal to these operational values: 115200 bps, 8 data bits, no parity, 1
stop bits (115200 8N1).
The following table lists the signals used on the RP console port.

Auxiliary Port Signals
The RP Auxiliary (AUX) port is a RJ-45 interface for connecting a modem or other data communication
equipment (DCE) device (such as another router) to the RP. The AUX port supports hardware flow control
and modem control.
The following table lists the signals used on the Auxiliary port.
