CONNECTING TO THE NETWORK

This chapter outlines the procedure for connecting the SEHI to your network. Ensure that your network meets the guidelines and requirements outlined in Chapter 2, Installation Requirements/ Specifications, before installing the SEHI to your network.

4.1CONNECTING THE SEHI TO THE NETWORK

The procedure for connecting network segments to the SEHI varies depending on the media and ports being connected. Refer to the following list and perform the procedure described in the subsections that apply to your SEHI:

•	Network Ports, SEHI-22/24	4.1.1
•	Network Ports, SEHI-32/34	4.1.2
•	EPIM-T	4.1.3
• EPIM-F1, F2, F3		4.1.4
•	EPIM-C	4.1.5
•	EPIM-A	4.1.6
•	EPIM-X	4.1.7

Prior to connecting the network cabling check the connectors for the proper pinouts as shown in Chapter 2.

4.1.1Connecting to Network Ports, SEHI-22 and SEHI-24

You attach unshielded twisted pair segments to the RJ45 Network Ports on the front panel of the SEHI. Each twisted pair port on the SEHI incorporates a Polarity Detection and Correction feature. The Polarity Detection and Correction feature allows the SEHI to pass data regardless of the polarity of the twisted pair segment’s receive link. Operating in this condition is not recommended and if this condition is discovered, the segment should be removed from the network and wired correctly by a technician.
