SEHI USER’S GUIDE 4-1
CHAPTER 4
CONNECTING TO THE NETWORK
This chapter outlines the procedure for connecting the SEHI to a network.
Ensure that the network meets the guidelines and requirements outlined in
Chapter 2,
Installation Requirements/Specifications, before installing
the SEHI.
4.1 CONNECTING THE SEHI TO THE NETWORK
This section details the procedure for connecting network segments to the
SEHI. Refer to the following list and perform the procedure described in
the subsections that apply to connecting the SEHI to a network:
• Network Ports, SEHI-22/24 4.1.1
• EPIM Ports 4.1.2 - 4.1.4
Prior to connecting the network cabling, check the connectors for the
proper pinouts as shown in Chapter 2.
4.1.1 Connecting to Network Ports, SEHI-22 and SEHI-24
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, the segment should be removed from the network and
wired correctly by a technician.
