EN104/EN108/EN116 hub. Each hub is listed individually when information is
provided that refers to a specific model.
Features
The Model EN104/EN108/EN116 hub has the following features:
• Four (on the Model EN104 hub), eight (on the Model EN108 hub), and
sixteen (on the
provide 10 megabit per second (Mbps) networking using simple unshielded

Normal/Uplink Push Button
The Normal/Uplink push button allows you to select Normal (MDI-X) wiring
for direct PC connection. The push button also allows you to select Uplink
(MDI) wiring for connection to a hub or a switch through port 4 on the
EN104 hub, port 8 on the
Model EN108 hub, or port 16 on the Model EN116 hub.
Model
This uplink configuration eliminates the need to use a crossover cable. The other
10BASE-T ports are permanently configured for normal wiring for connection
to a PC.

Rear Panel
The rear panel of the hub has a BNC port that you can use to connect to a
backbone network or other PCs using thin coaxial cable.
The rear panel of the Model EN108 hub and the Model EN116 hub also has an
AUI port in addition to the BNC port. You can use the AUI port with the
appropriate transceiver to connect the hub to a backbone network using thin
coaxial cable, thick coaxial cable, fiber optic cable, or 10BASE-T wiring.
The rear panel also includes a DC power receptacle.
