1. Introduction
Welcome to the World of Mini-Networking.
In the modern business society, communication and sharing information is crucial.
Computer networks have proven to be one of the fastest modes of communication.
Lantech Mini Switch 800 is compacts and attractively designed for desktop use.
It is an ideal solution for small office or SOHO network user. The Switch provides
wire-speed, Fast Ethernet switching function that allows high-performance,
low-cost connection.
Mini Switch 800 will automatically detect the speed of the device that you plug
into it to allow you to use both 10 and 100Mbps device. It features a store-and
forward switching and it can auto-learn and store source address.

- RJ-45 Ports:
8x 10/100N-Way auto-sensing for 10Base-T or 100Base-TX connection.
- Auto MDI/MDI-X:
It can detect the cable straight connect NIC or cascade to a hub or
switch without change the connector, the maximum distance between the
Switch to another device is 100 meters.
- DC Power Connector:
Plug DC Power Adapter’s female end into this device, and the male end
of the DC Power Adapter into a power outlet. The Adapter supply the
Switch with Voltage 7.5V, Current 1000mA.

3.Network Application
This section provides you a few examples of network topology in which the Mini
Switch 800 is used, the Switch is design to be used as a desktop or segment
The switch automatically learns node address, which are subsequently used to
filter and forward all traffic based on the destination address.
•Stand Alone
The Mini Switch 800 is designed to be a compact desktop size switch,
which is an ideal solution for small workgroup. The Switch can be used as
a standalone switch to which personal computers, server, printer server are
directly connected to form small workgroup.

•Enlarge Your Network
You can use Uplink port of the Mini Switch 800 to connect with another
hub or switch to interconnect each of your small switched workgroup to
form a large switched network.
You can connect anyone switch port to hub or switch without crossover
cable by the Auto MDI/MDI-X function.
In the below illustration, two Switches are used to interconnect two small
workgroup. All the devices in this network can communicate with each
other. Connecting servers to the Switch allow other users to access the
server’s data.

4. Trouble Shooting
The Mini Switch 800 can be easily monitored through panel indicators to assist in
identifying problems. This section describes common problems you may encounter
and where you can find possible solutions.
•Diagnosing LED Indicators
If Link indicator does not light up after making a connection, you may
check whether network interface (e.g., a network adapter card on the
attached device), network cable, or switch port is defective or not. Be
sure the cable is plugged into both the Switch and corresponding device.
Verified the proper cable type is used and its length does not exceed
specified limits.
If the power indicator does not turn on when the power cord is plugged
in, you may have a problem with power outlet, or power cord. However,
if the switch powers off after running for a while, check for loose power
connection, power loses or surges at power outlet. If you still cannot
resolve the problem, contact your local dealer for assistance.
RJ-45 Ports: Use unshielded twisted-pair (UTP) or shield twisted-pair (STP)
cable for RJ-45 connections: 100Ω Category 3,4 or 5 Cable for 10Mbps
connections or 100Ω Category 5 Cable for 100Mbps connections. Also
be sure that the length of any twisted-pair connection does not exceed 100
meters ( 328 feet ).
