4	GND	—	Signal ground
5	GND	—	Signal ground
6	RxD	Input	Receive Data
7	DSR	Input	Data Set Ready
8	NC	—	No connection

Note The NRP console port does not support hardware flow control. To ensure proper operation, configure any terminal equipment connected to the console port for no hardware flow control or no flow control.

NRP Auxiliary Port

The NRP auxiliary (AUX) port supports hardware flow control and modem control. Table B-5 lists the signals for this connector.

Table B-5: NRP AUX Port Connector Signals

Pin	Signal	Direction	Description
1	RTS	Output	Request To Send (for hardware flow control)
2	DTR	Output	Data Terminal Ready (for modem control)
3	TxD	Output	Transmit Data
4	GND	—	Signal ground
5	GND	—	Signal ground
6	RxD	Input	Receive Data
7	DSR	Input	Data Set Ready (for modem control)
8	CTS	Input	Clear To Send (for hardware flow control)

NRP Network Manangement Ethernet Port

The NRP network management Ethernet (ETH) port provides for out-of-band network management for the NRP. Table B-6 lists the signals for this connector.

Table B-6: NRP ETH Port Connector Signals

Pin	Signal	Direction	Description
1	TxD+	Output	Transmit Data +
2	TxD-	Output	Transmit Data -
3	RxD+	Input	Receive Data +
4	NC	—	No connection
5	NC	—	No connection
6	RxD-	Input	Receive Data -
7	NC	—	No connection
8	NC	—	No connection

NRP Fast Ethernet Port

The Fast Ethernet (FE) port can be used to connect the NRP to a 100BaseT LAN. Table B-7 lists the signals for this connector.

Table B-7: NRP FE Port Connector Signals

Pin	Signal	Direction	Description
1	TxD+	Output	Transmit Data +
2	TxD-	Output	Transmit Data -
3	RxD+	Input	Receive Data +
4	NC	—	No connection
5	NC	—	No connection
6	RxD-	Input	Receive Data -
7	NC	—	No connection
8	NC	—	No connection

Note The 100BaseT (FE) port on the NRP does not meet the requirements of Bellcore GR 1089 Core, Section 4.5.9 (intrabuilding lightning surge) with unshielded twisted pair cabling attached. Therefore, if the Cisco 6400 is used in an environment where lightning-induced transients are likely to couple to the signal lines, the use of shielded interconnection cables for the 100BaseT port is required.

Note In North America, the positive connection is known as tip, and the negative connection is known as ring.

Alarm Terminal Block on the Cisco 6400

Figure B-12 shows the external alarm monitoring terminal block on the Cisco 6400. This facility accommodates the attachment of a customer-supplied external alarm monitoring facility to alert site personnel to the existence of an alarm condition in the Cisco 6400.

Figure B-12: Alarm Terminal Block on the Cisco 6400

Note Figure B-12 shows the wiring configuration for normally open (NO) alarm relays. If you wire the Cisco 6400 in series with other equipment for the alarm indicators, use the normally closed (NC) terminal. If you wire the Cisco 6400 in parallel with other equipment, use the NO terminal.

Cisco 6400 DC Power Terminal Blocks

Figure B-13 shows the location of two identical system power terminal blocks on the rear of the Cisco 6400 chassis. These terminal blocks are associated with the power entry module (PEM) bays in the front of the chassis (see Figure 1-1). The upper terminal block services the top PEM bay; the lower terminal block services the bottom PEM bay.
