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-) |
