Dual Speed Switch
NTRODUCTION
I
Thanks for purchasing one of the MIL-S3100 family of
dual speed switches. They provide a dedicated bandwidth
of 10/100 Mbps throughput per port to the desktop. With
features like auto-negotiation and half/full duplex, these
switches offer smooth network migrations and easy
upgrades to network capacity.
The MIL-S3100 family of dual speed switches has the
following features:
! Complies with IEEE802.3, IEEE802.3U standard
! 4 or 8 10/100 Mbps switching ports
! Auto-Negotiation is supported for each port.
! One up-link port provided for cascading
! Visual diagnostic LED’s supported
! Palm size
! External power adapter

RJ-45 10/100 Dual Speed Switching Ports
There are 4 or 8 RJ-45 ports on the front panel. The
10/100 Mbps speed and full/half duplex modes o f the
ports are automatically determined when users
connect the switch to 10Base-T and 100Base-TX
devices.
Uplink Port
One uplink connector (MDI) on the front panel allows
users to connect to a switch or a hub, using straightthrough Category 5 twisted pair cable as figure shown.
Connecting to a desktop
The ports are used for connecting the switch to the
desktops, to form a small network. You can build the
network as the figure shows. 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.
Connecting to a Switch or a Hub
Switch-to-switch or switch-to-hub connections are made
by connecting the uplink port of 10/100 Dual speed switch
to a port of the other hub/switch.
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.
ALL MOUNT
W
The 4 or 8-port 10/100 Dual speed switch can be mounted
to the wall or to the 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 switch on the wall using the keyholes
provided on the bottom of the switch.
CC COMPLIANCE STATEMENT
F
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 inter ference, 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 ha s the equipment
installed into a different power outlet so that the
equipment and the receiver are on different branch
circuits.
AFETY INSTRUTIONS
S
1. This product should be operated from the type of
power source indicated on the marking label. If you
are not sure of the type of power available, consult
your dealer or local power company.
2. This product is equipped with a three-wire
grounding type plug, a plug having a third
(grounding) pin. This p lug will only fit into a
grounding type power outlet. This is a safety feature.
If you are unable to insert the plug into the outlet,
contact your electrician to replace your obsolete
outlet. Do not defeat the purpose of the grounding
type plug.
3. Do not allow anything to rest on the power cord. Do
not locate this product where persons will walk on
the cord.
! 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.
4. If an extension cord is used with this product, make
sure that the total ampere ratings on the products
plugged into the extension cord do not exceed the
extension cord ampere rating. Also make sure that
the total of all products plugged into the wall outlet
does not exceed 15 amperes.
5. Never push objects of any kind into this product
through cabinet slots as they may touch dangerous
voltage points or short out parts that could result in a
risk of fire or electric shock. Never spill liquid of
any kind on the product.
