Ethernet cables are divided into two categories: straight-through and crossover.
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.
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.
Note:
In making network cables, shielded cables are preferred for the sake of
electromagnetic compatibility.

7.4.6 Connecting the Interface Cable

Step 1: Plug one end of the cable to an Ethernet port of the FE module on the firewall
and another end to the desired device. (For a PC or Router, use a crossover cable; for
a HUB or LAN switch, use a straight-through cable.)
Step 2: Power up the firewall and check state of the LINK LED on the FE module. ON
means a link is present. OFF means no link is present and you should check the
connection.
