Ethernet Hub Installation Guide
Connect to a Network Using the BNC Port
The BNC port on the rear panel of the hub is used for connecting to a thin
coaxial segment. You can connect other Model EN308
TC
hubs, servers,
workstations, or other devices to the BNC port. A BNC T- connector is inserted
in the port, and the BNC 50 Ω terminator terminates the connection at each end
device. By using the BNC port for cascading, you treat each connected hub as
just another node on the coaxial segment.
The separation marks in the coaxial cable between the hubs in the following
illustration represent the incorporation of other devices and show that
interconnection is not limited to hubs.
Note: Ethernet specifications limit a BNC segment to 30 BNC
connections, specify a minimum of 1.64 feet (0.5 m) between any two
stations, and limit segments to 607 feet (185 m) in length.
