INSTALLATION REQUIREMENTS/SPECIFICATIONS
2.1.5Thin-net Network Requirements for the EPIM-C Module
When you connect a thin-net segment to the SEH (via an EPIM-C), your network must meet the following requirements:
Cable Type
50 ohm RG-58A/U type coaxial cable must be used when making up a thin-net cable segment.
Length
The thin-net segment must be no longer than 185 meters.
Terminators
A 50 ohm terminator must be connected 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, then 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.
Warning: Connecting a thin-net segment to earth ground at more than one point could produce dangerous ground currents.
