Cables for RJ-45 Ethernet LAN Interfaces
A twisted pair cable with four pairs and RJ-45 connectors must be used for
10BASE-T/100BASE-TX/1000BASE-T (10/100/1000BASE) connections.
Caution Do not plug a phone jack into an RJ-45 switch port because you could
damage the switch. Use only twisted pair cables with RJ-45 connectors.
Pin assignments Each pair of twisted pair cables is identified by related colours. For example,
one wire might be red, and the related wire would be red-and-white stripe. An
RJ-45 connector must be fitted to both ends of the cable. The following diagram
shows RJ-45 connectors and the pin layout.
