Grounding and Insulation
The only issue that remains before we have a functioning single segment
10BASE5 Ethernet network is grounding the coaxial cable and insulating
the connectors. The backbone cable must be connected to a reliable earth
ground at only one point. The actual connection to ground can be made at
any point on the cable, but is usually accomplished at an N-type
connector, which allows for convenient attachment to the coaxial shield
through the connector body.
All connections, other than the grounded connection, must be insulated
from any other metallic surface to avoid inadvertent grounding and
creation of ground loops (multiple paths to ground).
Once the connectors are insulated, the coaxial cable is grounded and the
workstations are connected to the transceivers, the single segment
network is ready for operation.
