Unpacking and Installing Your ELS10-26

a.Check that the 10BASE-T device at the other end of the twisted pair segment is ON and connected to the segment.

b.Verify that the RJ45 connectors on the twisted pair segment have the proper pinouts (Figure 2-7) and check the cable for continuity.

2.6.2 Connecting a UTP Segment to the FE-100TX

An FE-100-TX installed in port slot 27 is often used to provide a connection between the ELS10-26 and a bridge, router, or switch. Usually, in this configuration, a “straight-through” cable is used and the Fast Ethernet Interface Module crossover switch shown in Figure 2-7 is set to “not crossed over.”

Normally, when connecting devices to like devices, crossing over of the transmit and receive pairs must occur. Before connecting a segment to the FE-100TX, check each end of the segment to
