PRODUCT INTRODUCTION  
2.1  
Models  
The Switch is a multi-speed, versatile network device combining both standard and "Big-Pipe" ports under the same hood.  
The Switch is a twenty-four (24) 100/10Mbps RJ-45 UTP/STP ports switch.  
2.2  
Key Features  
Twenty-four (24) 100/10Mbps Switch ports.  
Store-and-Forward technology.  
Auto-Negotiation support for each TP port.  
IEEE 802.3x Flow-Control support for Full-Duplex operation.  
Back-Pressure support for Half-Duplex operation.  
Bridging capability for 100Mbps and 10Mbps segments.  
All ports support Auto-MDIX function.  
2.3  
Front Panel  
For 19 inches case  
2.3.1 100/10Mbps TP Ports  
Each 100/10Mbps TP port provides an Auto-Negotiation function that senses for the attached device's maximum operating  
speed and automatically sets the Switch to operate at that speed. Users only need to connect a network device into any TP  
port.  
2.3.2 Cabling  
10Mbps - When transmitting at 10Mbps Category 3, 4 or 5 TP cabling with RJ-45 sockets can be used.  
100Mbps -To transmit at 100Mbps requires Category 5 TP cabling.

2.4.1 Power Socket  
The Power Socket is designed to be used with the power cord included in the product package.  
Attach the female end of the cord to the power connector on the back panel.  
Attach the male end of the cord to a grounded power outlet.  
2.4.2 Fan  
Note: Please keep the fan area clear, so that the cooling function is not impaired.

INSTALLATION  
The Switch is "Plug & Play". It does NOT require software configuration. Users can immediately use any of the features of this  
product simply by attaching the cables and turning on the power.  
3.1  
To locate the switch on a desktop  
Attach the four (4) rubber feet included in the product package to the bottom of the Switch, one in each corner.  
Place the Switch on a clean, flat desk or tabletop close to a power outlet.  
Plug in all network connections and the power cord.  
Turn the power switch to "On".  
3.2  
Rackmount placement  
Attach one (1) rackmounting bracket on each side of the Switch front panel and secure each bracket with the provided  
screws.  
Use the other provided screws to secure each Switch to the rack.  
Use the other provided screws to secure each Hub to the rack.

HELPFUL SUGGESTIONS  
4.1  
Prior to Installation  
Before installing the Switch and connecting network devices, it is important to plan the network's layout. Things you should  
consider include:  
Dedicated Bandwidth: File servers and other high-traffic hardware improve their performance if they have their own  
dedicated 10Mbps or 100Mbps bandwidth.  
Full-Duplex: Determine which devices support Full-Duplex connections.  
Fast Ethernet: Make sure rules for cable lengths and categories are followed.  
Auto-Negotiation: Devices with different speeds may be easily swapped when the other end of the cable is fixed to a port  
with Auto-Negotiation.  
Note: If you are using the last port’s Crossover TP connector, you cannot use the last port’s regular connector. If you use both  
of the last port's TP connector’s at the same time your Switch will not operate properly.  
4.2  
Half- and Full-Duplex  
The Switch supports both Half- and Full-Duplex modes for 10BASE-T and 100BASE-TX.  
In Half-Duplex mode: Data cannot be transmitted and received at the same time. Attached devices must finish transmitting  
data before they can receive data.  
In Full-Duplex mode: Data can be transmitted and received at the same time.  
However:  
Full-Duplex transmission is only possible between two devices with a dedicated link (e.g., Switch-Switch, Switch-PC)  
Both devices must have Full-Duplex capability  
Both devices must be set to Full-Duplex (e.g. Auto-Negotiation – Auto-Negotiation, Non-Auto-Negotiation to  
Non-Auto-Negotiation)  
The 100BASE-TX/10BASE-T ports on the Switch detect and set the line's operating mode by using their Auto-Negotiation  
function.  
4.3  
Fast Ethernet  
100BASE-TX is called "Fast Ethernet". In Fast Ethernet data travels ten times faster (100Mbps) than in traditional Ethernet  
(10Mbps).  
Below is a list of the cable types and connectors supported by the Switch for 10BASE-T and 100BASE-TX networks.

Cat. 5 TP  
RJ-45  
Note: If your 10BASE-T network currently uses Category 5 TP cabling, you can instantly upgrade the network to a  
100BASE-TX network by changing network devices.  
4.4  
Auto-Negotiation  
Every 100/10Mbps dual speed port on the Switch has a built-in "Auto-Negotiation" function. This technology automatically  
sets the best possible bandwidth as soon as a connection is established with another network device. (Usually at Power “On”  
or Reset.) This capability is achieved via the Switch’s Auto-Negotiation function that automatically detects the modes and  
speeds the second (attached) device is capable of.  
Evaluating Auto-Negotiation Capability:  
If attached device is:  
The Switch Will Automatically Set Its TP Ports to  
Operate At:

100Mbps (100BASE-TX, Half-Duplex)  
200Mbps (100BASE-TX, Full-Duplex)  
10Mbps (10BASE-T, Half-Duplex)

10Mbps  
no Auto-Negotiation  
10Mbps  
with Auto-Negotiation  
20Mbps (10BASE-T, Full-Duplex)  
Note: If the attached device is set to a fixed mode (ex: Forced Full-Duplex) it will not operate as an Auto-Negotiation device.  
4.5  
MAC Address Table  
Every Ethernet data packet includes both source and destination addresses. This six (6) bytes ID is called the MAC (Media  
Access Control) Address.  
The Switch can automatically learn and store MAC addresses. However, the MAC address table is volatile: it disappears  
when the Switch is powered “Off” or reset.  
Note: When the network needs reconfiguration, we recommend turning off the power first. After all nodes have been moved,  
turn the Switch back "On" to rebuild the internal MAC address table.

Sample Application  
The optimal application for the Switch is as a "big pipe" backbone interconnecting file servers with bandwidth-hungry  
workgroups, departments, and offices.
