Figure 4-10 Ethernet cable
Ethernet cables fit into the following two categories:
z Straight-through cable, at both ends of which, wires are crimped in the RJ-45
connectors in the same sequence. The cable connects different categories of
devices, such as a terminal device (PC for example) or router to a Hub or LAN
switch.
z Crossover cable, at both ends of which, wires are crimped in the RJ-45 connectors
in different sequences. The cable connects the same category of devices, such as
PC to PC or PC to router. You can make crossover cables yourself as needed.
Caution:
In making network cables, shielded cables are preferred for electromagnetic
compatibility sake.
III. Connecting the Ethernet cable
Caution:
z Prior to connection, please identify the mark on the interface in order to plug
correctly.
z While connecting the Ethernet cable to a LAN Switch, plug the cable into the
10/100BASE-T interface marked with MDIX.
Follow the steps below to connect an Ethernet cable:
1) While connecting the Router with a PC or a Router, please use the crossover
cable, plug one end of the cable to an Ethernet interface of the Router, and plug
another end to a PC or a Router. While connecting the Router with a Hub or a LAN
Switch, please use the straight-through network cable, plug one end of the cable
to an Ethernet interface of the Router, and plug another end to a HUB or LAN
