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

TP
hub, port 6 on the Model EN106
TP
hub. This uplink configuration eliminates the need to use a crossover
TP
hub, or port 8 on the Model
cable. The other 10BASE-T ports are permanently con figured for normal wiring
for connection to a PC.
Rear Panel
The rear panel of the hub has a ground clip and a receptacle for the power

No nearby heat sources such as direct sunlight, warm air
exhausts, or heaters.
Operating humidity Maximum relative humidity of 90%, noncondensing.
Ventilation Minimum 2 inches (5.08 cm) on all sides for cooling.
Adequate airflow i n room or wi rin g clos et.
Operating
conditions
Service access Minimum 12 inche s (19. 68 cm ) front and back for service access
Power Adequate power source within 6 feet (1. 83 m ).
Wiring hardware Wiring hardware, such as punchdown blocks or patch panels,
At least 6 feet (1. 83 m) to nearest source of elec tromagnetic
noise (such as photoc opy machine or arc wel der).

should be complete before instal li ng the hub.
Install the Hub
To install your hub on a flat surface, you do not need any special tools. Be sure
the hub is positioned 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 holes
on the back of the hub and mark the wall to match the location of the mounting
holes on the hub . At the marked l ocation, 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.
