2.Ethernet interface (RJ45 connector)
By using of the 5 categories or above 5 categories twisted pair cable to connect Ethernet, LSW5003
series Ethernet switch interfaces (10/100/1000M) adopt RJ45 connector and support MDI/MDIX
auto-negotiation. When you use the interfaces, please adopt 5 categories twisted pair cable and RJ45
connector to make network cable.

Ethernet electric interface adopt 5 categories twisted pair cable to connect Ethernet, as shown in
Figure1-5.

For different usage, Ethernet twisted pair cables can be divided into straight-through and crossover
cables:
Standard cable: is also called straight-through cable. The sequences of the twisted pairs crimped in the
RJ-45 connectors at both ends are the same. It connects a terminal device (PC or router) to a HUB or
LAN Switch. A standard cable is provided for you along with the device.
Crossover cable: The sequences of the twisted pairs crimped in the RJ-45 connectors at both ends are
different. It connects a terminal device (PC or router) to another terminal device. You make crossover
cables by yourself.
