Cabletron Systems SEHI100TX- Manuel D’Utilisation

This chapter outlines the procedure for connecting the SEHI to a network. 
Ensure that the network meets the guidelines and requirements outlined in 
Chapter 3, Installation Requirements and Specifications, before 
installing the SEHI.

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 
connecting the SEHI to a network:

•

Network Ports

•

EPIM-100TX

•

EPIM-100FX

Prior to connecting the network cabling, check the connectors for the 
proper pinouts as shown in Chapter 3.

Attach UTP 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.

Connect the twisted pair segments to the SEHI as follows:

1. Insert the RJ45 connector from each twisted pair segment into the
