Model EN104/EN108/EN116 Ethernet Hub Installation Guide
Connect to a Network Using the AUI Port
The AUI port on the rear panel (found only on the Model EN108 hub and the Model EN116 hub)
is normally used for connecting a thic k coaxial segment.
With the right type of transceiver, you can use the AUI port to connect to most types of network
media, including 10BASE-T twisted pair cable or thin coaxial, thick coaxial, and 10BASE-FL
fiber optic cables.
To complete the installation, connect the power cord first to the power receptacle on the hub
rearpanel and then to the power outlet on the wall. When power has been applied to the hub:
• The green Pwr (Power) LED on the front panel i s on.
• The green Link LED on each connected port is on.
• The green Active LED on each connected AUI port is on.
• The green Active LED on each connected BNC port is on.
If there are any problems, refer to “Troubleshooting Information .”
Note: All transceivers connected to the AUI port must have the signal quality error
(SQE) test function disabled. Refer to your transceiver documentation for information
about disabling the SQE test function.
Note: Ethernet specifications limit thick coaxial segments to 100 stations and
1,640 feet (500 m) in length, and they specify that the AUI cable between the hub
and the transceiver is limited to 164 feet (50m).
