RJ-45 Pin Assignments

Pin Number	Assignment

1	Tx+

2	Tx-

3	Rx+

6	Rx-

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

All ports on this switch support automatic MDI/MDI-X operation. In straight- through cables, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The table below shows the 10BASE-T/ 100BASE-TX MDI and MDI-X port pin outs:

Pin MDI-X	Signal Name	MDI Signal Name

1	Receive Data plus (RD+)	Transmit Data plus (TD+)

2	Receive Data minus (RD-)	Transmit Data minus (TD-)

3	Transmit Data plus (TD+)	Receive Data plus (RD+)

6	Transmit Data minus (TD-)	Receive Data minus (RD-)
