Introduction
Wellcome 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 modesof communication.
The 8-Port Switch are compact and attractively designed for
desktop use. They are ideal solution for small office or SOHO
network user. The Switches provide wire-speed, Fast Ethernet
switching function that allows high-performance, low-cost
connection.
The Switches will automatically detect the speed of the device that
you plug into it to allow you to use both 10 and 100Mbps device.
They feature a store-and forward switching and it can auto-learn
and store source address on an 1K-entry MAC address for
respective and 1MbBuffer.

??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 9V, Current 800mA.

Network Application
Thissectionprovidesyouafewexamplesofnetworktopologyin
which the 8-Port Switch is used, the Switch is design to be used
as a desktop or segment switch.
The switch automatically learns node address, which are
subsequently used to filter and forward all traffic based on the
destination address.
Stand Alone
The 8-Port Switch is designed to be a compact desktop size
switch which is a ideal solution for small workgroup. The Switch
canbeusedasastandaloneswitchtowhichpersonalcomputers,
server, printer server are directly connected to form small
workgroup.

Enlarge Your Network
You can use Uplink port of the 8-Port Switch to connect with
another hub or switchto 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.

Trouble Shooting
The Switch 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
adaptercardontheattacheddevice),networkcable,orswitch
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.
??Power
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.
??Cabling
RJ-45 Ports: Use unshielded twisted-pair (UTP) or shield
twisted-pair (STP) cable for RJ-45 connections: 100O
Category 3,4 or5Cable for 10Mbps connections or 100O
Category 5 Cable for 100Mbps connections. Also be sure that
thelengthofanytwisted-pair connection does not exceed 100
meters ( 328 feet ).
