RJ-45 Connector Pin Assignments
Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.
10BASE-T/100BASE-TX Pin Assignments
An Ethernet or Fast Ethernet twisted-pair link segment requires two pairs of wires. Each wire pair is identified by two different colors. Each wire pair must be attached to the RJ-45 connector in a specific orientation detailed below.
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 1000BASE-T 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-) |
4, 5, 7, 8 | Not used at 10/100 Mbps | Not used at 10/100 Mbps |
