CONNECTING TO THE NETWORK

4.1.2Connecting to Network Ports, SEHI-32 and SEHI-34

The SEHI-32 has a 50-pin Champ connector, while the SEHI-34 has two 50-pin Champ connectors. This configuration of the SEHI allows you to run a 50-pin feeder cable from the SEHI to a punch down block. Each Champ connector supports 12 10BASE-T, twisted pair segments.

Note: Refer to Appendix A for information about wiring the SEHI to a punch down block.

To connect the SEHI into an existing twisted pair wiring system:

1.Connect a 50-pin feeder cable to the Champ connector on the SEHI as shown in Figure 4-2.

2.Attach the feeder cable to the punch down block, or patch panel.

In most cases, you can connect the feeder cable directly to a Champ connector located on the punch down block. If not, you must wire the feeder cable to the punch down block using the punch down information in Appendix A.

3.At the device end of a segment, attach the segment to a 10BASE-T compliant Ethernet device.
