3.5.1 Connecting a Twisted Pair Segment to an EPIM-T
Before connecting a segment to the EPIM-T, check each end of the
segment to determine wire crossover. If the wires do not cross over, use
the switch on the EPIM-T to internally cross over the RJ45 port. Refer to
Figure 3-12 to properly set the EPIM-T crossover switch.
