A.2.3 Thin-Net Network Requirements for the EPIM-C
When you connect a thin-net segment to the SEH (via an EPIM-C), your
network must meet the following requirements:
Cable Type
Use 50 ohm RG-58A/U coaxial cable to make up a thin-net segment.
Length
The thin-net segment must be no longer than 185 meters.
Terminators
Connect a 50 ohm terminator to the far end of each thin-net segment.
Connectors
A maximum of 29 tee-connectors may be used throughout the length of
cable segment for host connections. If an excessive number of barrel
connectors are used within the cable segment, such as finished wall plates
with BNC feed-throughs, a reduced number of host connections may be
required. For special network design, contact Cabletron Systems
Technical Support.
Grounding
For safety, ground only one end of a thin-net segment. Do NOT connect
EPIM BNC ports to earth ground.
For safety, only one end of a thin-net segment should be
connected to earth ground. Connection to earth ground at
more than one point on the segment may cause dangerous
ground currents.
