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 eli minates the need to use a crossover
cable. The other 10BASE-T ports are pe rm anently 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 w ith 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.

Install the Hub
To install your hub on a flat surface, you do not need any special tools. Be sure the hub is
positio ned with at least 2 inches of space on all sides for ventilation.
To install the hub on a wall, measure the distance between the mounting hole on the back of the
hub and mark the wall to match the location of the mounting holes on the hub. At the marked
location, screw into the wall the two screws that you received with the mounting kit included in
your package contents. Be sure to choose a location that is near the devices to be connected, is
close to an electrical outlet, and provides at least 2 inches of space all around the hub for
ventilation.
Connect a PC to the Hub
You can connect PCs, Apple Macintosh computers, UNIX workstations, or any device equipped
with a 10BASE-T Ether net interf ace to the RJ-45 ports on your hub by using twisted pair Ether n et
cables.
To connect any of the RJ-45 ports on your hub to a PC, use a regular straight-through UTP cable.
If you are connecting using port 4 on the Model EN104 hub, port 8 on the Model EN108 hub, or
port 16 on the Model EN116 hub, set the Normal/U plink push button to Normal .
(The Model EN108 hub is

Connect the Hub to a NetworkConnect the Hub to a Network
Cascading refers to connecting hubs together to increase the number of ports or the number of
users supported on the network. The 10BASE-T ports can be used to cascade hubs together.
The twisted pair cable extended from a 10BASE-T port (or UTP port) is called a twisted pair
segment and can be up to 100 meters (m) in length. The 10BASE-T ports, with the exception of
port 4 on the Model EN104 hub, port 8 on the Model EN108 hub, or port 16 on the Model EN116
hub, are MDI-X (or Norm al) ports . Use the following table as a guide for selecting the appropriate
network ca ble.

Connect to a Network Using the BNC Port
The BNC port on the rear panel of the hub is used for connecting to a thin coaxial segment. You
can connect other Model EN104/EN108/EN116 hubs, servers, workstations, or other devices to
the BNC port. A BNC-T connector is inserted in the port, and the 50 Ω te rm inator terminat es the
connecti on at each end device. By usi ng the BNC port for cascading, you treat each connected hub
as just another node on the coaxial segm ent.
The separation marks in the coaxial cable between the hubs in this illustration represent the
incorpor ation of other devices and show that interconnection is not limited to hubs.

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 con n ecting 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.
Note:
All transceivers connected to the AUI port must have the signal quality error
(SQE) test function disabled. Ref er to your transceiver documentation for information
about disabling the SQE test function.

Make sure connected devices are operating in
half-duplex mode. The hub is not compatible
with devices that operate in full-duplex mode.
If y ou suspect that there might be a defective
device on the network, disconnect devices one
at a time to isolate the defective unit on the
network.
If the network is extremely busy, you may have
to segment the network with an Ethernet switch
such as a NETGEAR Ethernet switch or to
upgrade your network to Fast Ethernet
operation.
Make sure the correct UTP cables are used.
See the table in the installation section of this
guide for cable use and Normal/Uplink push
button information. Note that home telephone
cables can cause a collision condition and
cannot be used in place of UTP cables.
Check for a bad cable, cable pairs that are not
correctly wired, or loose connectors. Make sure
that there is power to both the hub and the
Ethernet transceiver on the connected device.

Twisted Pair Cables
For two devices t o communicate, the transm itter of ea ch device must be connected to the rece iver
of the other device. The crossover function is usually implemented intern ally as part of the
circuitry in the dev ic e. Most ports on s wit che s and r epe aters ha v e medi a-dep ende nt inter f ac es wit h
crosso ver ports. These ports are referred to as MDI-X or Normal ports. Computer and workstation
adapter cards are usu ally media- dependent interface ports referred to as MDI or Uplink ports.
