CONNECTING TO THE NETWORK

4.1.2Connecting Network Ports SEH-32 and SEH-34

The SEH-32 has a 50-pin Champ connector, while the SEH-34 has two 50-pin Champ connectors. This configuration of the SEH allows you to run a 50-pin feeder cable from the SEH 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 SEH to a punch down block.

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

1.Connect a 50-pin feeder cable to the Champ connector on the SEH 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.
