NOTE:
 Before connecting a network, it's recommended to set it as the switch basically.
 ping or the tracert command can be used to make sure of the interoperability of the switch and the network
after a network connection of the switch.
 When a port status LED of the switch flashed on and off after a network connection of the switch, and the
switch didn't react to the command, there is a possibility that a broadcast packet is being sent/receive for
the switch. Cut a network connection of the switch in this case and readjust the switch. After it, connect the
switch once again.
5.1 Network connection by a twisted pair cable
5.1.1 Twisted pair cable
A cable of a twisted pair consists of 4 sets of twisted insulated wire. That's advantage in
sending analog signal and sending data on the shorter distance mainly. The maximum
transmission distance is 100m.
I. About RJ45 connector
A twisted pair cable connects network equipment through RJ-45 connector in both ends.
RJ-45 connector is indicated on Figure 5-1.
