Figure 3-3. Attaching a Thin-Net Segment

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.
