RJ-45 10/100 Dual Speed Ports  
Connecting to a Switch or a Hub  
There are 8 RJ-45 ports on the front panel. The speed  
of the port is automatically determined when you  
connect the hub to 10Base-T and 100Base-TX  
devices.  
Hub-to-hub connections are made by connecting the  
uplink port of the 10/100 dual speed hub to a port of the  
other hub/switch.  
With 100Base-TX, the maximum network distance is  
approximately 205 meters with UTP cable. The maximum  
length between hubs or switch-to-hub is 100 meters.  
Uplink Port  
One uplink port (MDI) on the front panel allows users to  
connect to a switch or a hub, using straight-through  
Category 5 twisted-pair cable as figure shown.  
Connecting to a desktop  
The hub is connected to the desktops, to form a small  
network. You can build the network as the figure shows.  
WALL MOUNT  
Wall  
The MIL-H3130 10/100 Dual Speed Hub can be mounted to the wall  
or to a flat surface.  
!
Screw one of the enclosed 1/2-inch wood screws  
into the surface, leaving approximately 1/4-inch of  
the threads exposed.  
!
Hang the hub on the wall using the keyholes  
provided on the bottom of the hub.  
FCC COMPLIANCE STATEMENT  
This equipment generates and uses radio frequency  
energy and if not installed and used properly, that is, in  
strict accordance with the instructions provided with the  
equipment, may cause interference to radio and TV  
reception. The equipment has been tested and found to

of FCC rules, which are designed to provide reasonable  
protection against such interference in a residential  
installation. However, there is no guarantee that  
interference will not occur in a particular installation.  
If you suspect this equipment is causing interference, turn  
your hub on and off while your radio or TV is showing  
interference. If the interference disappears when you turn  
the hub off and reappears when you turn the hub on,  
something in the hub is causing interference.  
You can try to correct the interference by one or more of  
the following measures:  
Reorient the receiving radio or TV antenna where  
this may be done safely.  
To the extent possible, relocate the radio, TV or other  
receiver away from the equipment.  
Plug the computer which has the equipment installed  
into a different power outlet so that the equipment  
and the receiver are on different branch circuits.
