Twisted-Pair Cable and 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 to FCC standards.
For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.
Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.
10BASE-T/100BASE-TX Pin Assignments
With standard straight-through 10BASE-T/100BASE-TX cable, pins 1 and 2 are used for transmitting data, and pins 3 and 6 for receiving data. The ‘+’ and ‘-‘ signs in the table below are used to represent the polari- ty of the wires that make up each wire pair.
Because all ports on this switch support automatic MDI/MDI-X opera- tion, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.
| | Straight-through RJ-45 Pin Assignment | |
| End 1 | End 2 | |
| 1 (Tx +) | 1 (Tx+) | |
| 2 (Tx -) | 2 (Tx -) | |
| 3 (Rx+) | 3 (Rx+) | |
| 6 (Rx-) | 6 (Rx-) | |
