Model EN516/EN524 Ethernet Hub Installation Guide
Connect to a Network Using the AUI Port
The AUI port on the rear panel of the 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.
To complete the installation, connect the power cord first to the power receptacle on the hub rear
panel and then to the power outlet on the wall. When power has been applied to the hub:
• The green Power LED on the front panel is on.
• The green Link/Rx LED on each connected 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 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 (50 m).
