TWISTED-PAIR CABLE AND PIN ASSIGNMENTS

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	Assignment1
1	Tx+

2	Tx-

3	Rx+

6	Rx-

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

Because 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 pinouts.

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-)

No other pins are used.

Note: If auto-negotiation is disabled for an RJ-45 port, the auto-MDI/ MDI-X pin signal configuration is also disabled.
