4.1.3 Connecting a 10BASE-T Segment to an EPIM-T
Before connecting a segment to the EPIM-T, check each end of the
segment to determine the proper 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 4-3 to properly set the EPIM-T crossover switch.

EPIM-T Crossover Switch
To connect an EPIM-T to a twisted pair segment, perform the following
steps:
1. Connect the twisted pair segment to the module by inserting the RJ45
connector on the twisted pair segment into the RJ45 port on the
module. See Figure 4-3.
2. Check that the EPIM’s LNK LED is on. If the LED is not on, perform
each of the following steps until it is:
a.
Check that the 10BASE-T device at the other end of the twisted
pair segment is powered up.
