Cabling Considerations
This Appendix describes the pin-to-pin connections for cables used with the Mediatrix 4104.
RJ-45 Cable
The RJ-45 connector is commonly used for network cabling and for telephony applications. It is used to wire
both ends identically so the signals pass straight through.
RJ-45 cabling is also known as Twisted-pair Ethernet (TPE), Unshielded twisted pair (UTP) and 10/100
Base-T.

Straight Through Cable
A RJ-45 straight through cable is used to connect a computer to a network device. For example straight
through cables are the type of cables that connect a computer to a network hub, network switch, and network
routers.
Warning:
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
