RJ-45 Port Pin Assignments

All LAN ports on the CheetahAccess Wireless Gateway support automatic MDI/ MDI-X configuration. This means that the pin signals in use will depend on whether the LAN port is operating in MDI or MDI-X mode. However, the WAN port is configured only for MDI-X mode.

Pin	MDI Signal Name*	MDI-X Signal Name*
1	Transmit Data (TD+)	Receive Data (RD+)
2	Transmit Data (TD-)	Receive Data (RD-)
3	Receive Data (RD+)	Transmit Data (TD+)
6	Receive Data (RD-)	Transmit Data (RD-)

Pins 4, 5, 7 and 8 are not connected.

*The “+” and “-” signs represent the polarity of the wires that make up each wire pair.

Caution: DO NOT plug a phone jack connector into any RJ-45 port. For Ethernet connections, use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.
