3.Check that the applicable LNK LED for the port is on. If the LED is off, perform each of the following steps until it is on:

a.Check that the 100BASE-TX device at the other end of the twisted pair segment is powered up.

b.Verify that the RJ45 connector on the twisted pair segment has the proper pinouts.

c.Check the cable for continuity.

d.Check that the twisted pair connection meets the cable specifications outlined in Section 3.1.2.

5.1.2Connecting to an EPIM-100TX

The EPIM-100TX is often used to provide a connection between the SEHI and a bridge, router, or switch. Normally, in this configuration, a “straight-through” cable is used and the EPIM crossover switch shown in Figure 5-2 is set to “not crossed over.”

The EPIM-100TX is also used to provide another RJ45 port to connect to a UTP segment. Before connecting a segment to the EPIM-100TX, check each end of the segment to determine if the wires have been crossed over for the proper connection. If the wires do not cross over, use the switch on the EPIM-100TX to internally cross over the RJ45 port. Refer to Figure 5-2 to properly set the EPIM-100TX crossover switch.
