Cisco ASR 9001 Router Port Connection Guidelines

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).

Table 1-3lists the signals used on the RP console port.

Table 1-3	RP Console Port Signals
Console Port Pin		Signal	Input/Output	Description
	1	RTS	Output	Request to Send
	2	—	—	(Not connected)
	3	TxD	Output	Transmit data
	4	GND	—	Signal ground
	5	GND	—	Signal ground
	6	RxD	Input	Receive data
	7	—	—	(Not connected)
	8	CTS	Input	Clear to Send

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.

Table 1-4lists the signals used on the Auxiliary port.

Table 1-4	RP AUX Port Signals
AUX Port Pin		Signal	Input/Output	Description
1		RTS	Output	Request to send
2		DTR	Output	Data terminal ready
3		TxD	Output	Transmit data
4		GND	—	Signal ground
5		GND	—	Signal ground
6		RxD	Input	Receive data
7		DSR	Input	Data set ready
8		CTS	Input	Clear to send
