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 thick 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.
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.

AUI cable between the hub and the transceiver is limited to 164 feet
(50 m).
