Dual Speed Switch  
INTRODUCTION  
Thanks for purchasing one of the MIL-S3100 family of dual speed switches. They provide dedicated bandwidths of  
10/100 Mbps throughput per port to the desktop. With features such as auto-negotiation and half/full-duplex, these  
switches offer smooth network migrations and easy upgrades to network capacity.

16 or 24 RJ-45 10/100 Dual Speed Switching Ports  
Connecting to a Desktop  
There are 16 or 24 RJ-45 ports on the front panel. The  
speed and full or half-duplex modes of the ports are  
automatically determined when users connect the switch  
to 10Base-T and 100Base-TX devices.  
The switch is connected to the desktop, to form a small  
network. You can build the network as shown in the  
figure.  
To improve the network efficiency, it is better to have 200  
Mbps full-duplex operation between the server and  
switch, if the LAN adapter on the server can operate in  
full-duplex mode.  
The 16 or 24 RJ-45 auto-negotiation ports simplify  
migration of 10 Mbps Ethernet to 100 Mbps Fast  
Ethernet.  
Normal/Uplink Push Button  
One normal/uplink push button on the front panel allows  
users to select the 16th or 24th port to connect to a PC or a  
hub or switch. With this normal/uplink push button  
feature, users can connect with network devices.  
A link LED is lit when there is a successful connection.  
The default setting is in the normal (MDI-X) position, i.e.  
the long button position. The port is configured to  
connect with a PC using a straight through twisted pair  
cable.  
Connecting to a Switch or a Hub  
When the push button is pressed (MDI), i.e., the short  
button position, connection is made with a hub or a  
switch using a straight through twisted pair cable.  
Switch-to-switch or switch-to-hub connections are made  
by connecting the 16th or 24th port to a port or to the other  
hub or switch with the normal/uplink push button pressed  
in.  
With 100Base-TX, the maximum network length is  
approximately 205 meters with UTP cable. The maximum  
length between hubs or switch-to-hub is 100 meters.

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 comply with the limits for a Class A computing device in accordance with the  
specifications in Subpart B of Part 15 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 switch on and off while your radio or TV is  
showing interference. If the interference disappears when you turn the switch off and reappears when you turn the switch  
on, something in the switch is causing interference.  
You can try to correct the interference by one or more of the following measures:  
!
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.  
!
!
Reorient the receiving radio or TV antenna where this may be done safely.  
If necessary, you should consult the place of purchase or an experienced radio/television technician for additional  
suggestions.
