6.1 100BASE-TX/10BASE-T Pin Assignments

With 100BASE-TX/10BASE-T cable, pins 1 and 2 are used for transmitting data, and pins 3 and 6 for

receiving data.

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, you can use straight-through cables for

all network connections to PCs or servers, or to other switches or hubs. In straight-through cable, 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-)
