Appendix C – Cable Connections
This cable information is provided for your reference only. Please ensure you only
connect the appropriate cable into the correct socket on either this product or your
computer.
If you are unsure about which cable to use or which socket to connect it to, please
refer to the hardware installation section in this manual. If you are still not sure about
cable connections, please contact a professional computer technician or NetComm for
further advice.

RJ-45 Network ports

All of the ethernet ports on the NB702/NB704 are 10/100 Mbps capable auto-sensing
Ethernet ports. Each port supports only unshielded twisted pair (UTP) cable using an
8-pin RJ-45 plug. The Auto-uplink feature senses the connection of uplink (MDI-II)
wiring using a straight-through twisted pair cable to any of the ethernet ports on the
NB702/NB704 switch to allow for connection to any port of an ethernet adapter,
ethernet switch or hub.

Twisted pair cables

Figures 1 and 2 illustrate the use of straight-through and crossover twisted pair cables
along with the connector.
