A schematic of a straight-through and a crossover cable is shown in
Figure 2-6 . If the wires do not cross over, use the switch on the FE-100TX
to internally cross over the RJ45 port. Figure 2-5 shows how to properly
set the FE-100TX crossover switch.
Figure 2-6 Twisted Pair Cabling
Connect an FE-100TX to a twisted pair segment as follows:
