Installation Procedures  
Prepare the Site  
Before you begin installing your hub, prepare the installation site. Make sure  
your operating environment meets the operating environment requirements of  
the equipment.  
Characteristic  
Requirement  
Temperature  
Ambient temperature between 0° and 40° C (32° and 104° F).  
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 in room or wiring closet.  
Operating  
conditions  
At least 6 feet (1.83 m) to nearest source of electromagnetic  
noise (such as photocopy machine or arc welder).  
Service access  
Minimum 12 inches (19.68 cm) front and back for service access  
and maintenance.  
Front and back clearance for cables and wiring hardware such as  
punchdown blocks.  
Power  
Adequate power source within 6 feet (1.83 m).  
Wiring hardware  
Wiring hardware, such as punchdown blocks or patch panels,  
should be complete before installing the hub.  
Install the Hub  
To install your hub on a at 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  
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 Devices to the Hub  
You can connect PCs, Apple Macintosh computers, UNIX workstations, or any  
device equipped with a 10BASE-T Ethernet interface to the RJ-45 ports on your  
hub by using twisted pair Ethernet cables.  
To connect any of the RJ-45 ports on your hub to a PC, use a regular straight-  
TP  
through UTP cable. If you are connecting using port 4 on the Model EN104 hub,  
TP  
TP  
port 6 on the Model EN106 hub, or port 8 on the Model EN108 hub, set the

Connect 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  
TP  
ports, with the exception of port 4 on the Model EN104 hub, port 6 on the Model  
TP  
TP  
EN106 hub, or port 8 on the Model EN108 hub, are MDI-X (or Normal) ports.
