Model EN104/EN108/EN116 Ethernet Hub Installation Guide
The following illustration shows cascading hubs together daisy-chain style and indicates the
setting of the Normal/Uplink push button on each hub.
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 EN104/EN108/EN116 hubs, servers, workstations, or other devices to
the BNC port. A BNC-T connector is inserted in the port, and the 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 this 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.
