3.2.2 Thin-Net Requirements
•
Cable -
Must be 50 ohm RG-58A type coaxial cable.
•
Length -
Must be no longer than 185 meters (607 ft.).
•
Termination -
A 50 ohm terminator at the far ends of each
thin-net segment.
•
Connections -
A maximum of 30 connections may be used
throughout a thin coaxial segment for host connections. If an
excessive number of barrel connections are used within the
cable segment, i.e. finished wall plates with BNC feed-
throughs, then a reduced number of host connections may be
required. For special network designs, contact Cabletron
Systems Technical Support.

WARNING:
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 allow for the occurrence of dangerous ground
currents.
