Port Pinouts

This appendix provides port pinouts for the switch router. This appendix includes the following sections:

• Console Port

• Auxiliary Port

• Gigabit Ethernet Ports

Console Port

The console port is an RJ-45 receptacle. Data terminal ready (DTR) and data set ready (DSR) handshake signals are supported. The Request To Send (RTS) signal tracks the state of the Clear To Send (CTS) signal. Table B-1 lists the console port pinouts.

Table B-1: Console Port Pinouts

Pin	Signal	Direction	Description
11	RTS/CTS	Output	Request to send / Clear to send
2	DTR	Output	Data terminal ready
3	TxD	Output	Transmit data
4	SGND	---	Signal ground
5	SGND	---	Signal ground
6	RxD	Input	Receive data
7	DSR	Input	Data set ready
81	RTS/CTS	Input	Request to send / Clear to send

1Pin 1 and pin 8 are connected.

Auxiliary Port

The Auxiliary port is an RJ-45 receptacle that supports remote console interfaces using a modem. Table B-2 lists the auxiliary port pinouts.

Table B-2: Auxiliary Port Pinouts

Pin	Signal	Direction	Description
1	RTS	Output	Request to send
2	DTR	Output	Data terminal ready
3	TxD	Output	Transmit data
4	SGND	---	Signal ground
5	SGND	---	Signal ground
6	RxD	Input	Receive data
7	DSR	Input	Data set ready
8	CTS	Input	Clear to send

Gigabit Ethernet Ports

Table B-3 provides cabling specifications for the Gigabit Interface Converters (GBICs) that you install into the Gigabit Ethernet port modules. Note that all GBIC ports have SC-type connectors, and the minimum cable distance for all GBICs listed is 6.5 feet (2 meters).

Table B-3: Gigabit Ethernet Port Cabling Specifications

GBIC	Wavelength (nm1)	Fiber Type	Core Size (micron)	Modal Bandwidth (MHz.km)	Cable Distance
SX2'3	850	MMF4	62.5 62.5 50.0 50.0	160 200 400 500	722 ft (220 m) 902 ft (275 m) 1640 ft (500 m) 1804 ft (550 m)

ZX8	1550	SMF	Not conditional	---	70 to 100 km

1nm = nanometers 2SX = short wavelength 3MMF only 4MMF = multimode fiber 5LX/LH = long wavelength/long haul 6Patch cord required (see the "Patch Cord" section for details) 7SMF = single-mode fiber 8ZX = extended distance
