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

RJ-45 Network Ports can connect any networking devices that use a standard LAN interface,
such as a Hub/Switch Hub or Router. Use unshielded twisted-pair (UTP) or shield twisted-pair
(STP) cable to connect the networking device to the RJ-45 Ethernet port. Depending on the
type of connection, 10Mbps or 100Mbps, use the following Ethernet cable, as prescribed.

10Mbps: Use EIA/TIA-568-100-Category 3, 4 or 5 cable.

100Mbps: Use EIA/TIA-568-100-Category 5 cable.


To prevent loss of signal, make sure that the length of any twisted-pair
connection does not exceed 100 metres.
