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 Model EN104 hub, port 8 on the Model EN108 hub, or port 16 on the Model EN116 hub. 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.
