Chapter 1  
INTRODUCTION  
This chapter describes the features of the Switch and some background information about  
Fast Ethernet switching technology.  
Fast Ethernet Technology  
The growing importance of LANs and the increasing complexity of desktop computing  
applications are fueling the need for high performance networks.  
A number of high-speed LAN technologies have been proposed to provide greater  
bandwidth and improve client/server response times. Among them, 100BASE-TX (Fast  
Ethernet) provides  
a
non-disruptive, smooth evolution from the current 10BASE-T  
technology. The non-disruptive and smooth evolution nature, and the dominating  
potential market base, virtually guarantee cost effective and high performance Fast  
Ethernet solutions in the years to come.  
100Mbps Fast Ethernet is a new standard specified by the IEEE 802.3 LAN committee. It  
is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive  
data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps  
Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a  
straightforward upgrade and takes advantage of the existing investment in hardware,  
software, and personnel training.  
Switching Technology  
Another approach to pushing beyond the limits of Ethernet technology is the development  
of switching technology. A switch bridge Ethernet packets at the MAC address level of  
the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN  
segments.  
Switching is a cost-effective way of increasing the total network capacity available to  
users on a local area network. A switch increases capacity and decreases network loading  
by dividing a local area network into different segments, which don’t compete with each  
other for network transmission capacity.  
The switch acts as a high-speed selective bridge between the individual segments. The  
switch, without interfering with any other segments, automatically forwards traffic that  
needs to go from one segment to another. By doing this the total network capacity is  
multiplied, while still maintaining the same network cabling and adapter cards.  
For Fast Ethernet networks, a switch is an effective way of eliminating problems of chaining  
hubs beyond the “two-repeater limit. A switch can be used to split parts of the network  
into different collision domains, making it possible to expand your Fast Ethernet network  
beyond the 205-meter network diameter limit for 100BASE-TX networks. Switches  
supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for  
bridging between the existing 10Mbps networks and the new 100Mbps networks.  
Switching LAN technology is a marked improvement over the previous generation of  
network bridges, which were characterized by higher latencies. Routers have also been  
used to segment local area networks, but the cost of a router, the setup and maintenance  
3
 
required make routers relatively impractical. Today switches are an ideal solution to most  
kinds of local area network congestion problems.  
Features  
·
·
The Switches were designed for easy installation and high Performance in an  
environment where traffic on the network and the number of user increase  
continuously.  
The Switches with their small, compact size were specifically designed for  
small to middle workgroups. These Switches can be installed where space is  
limited; moreover, they provide immediate access to a rapidly growing network  
through a wide range of user-reliable functions.  
·
The Switches are ideal for deployment with multiple high-speed servers for  
shared bandwidth 10Mbps or 100Mbps workgroups. With the highest band-  
width 200Mbps (100Mbps full-duplex mode), any port can provide worksta-  
tions with a congestion-free data pipe for simultaneous access to the server.  
·
·
The Switches are expandable by cascading two or more switches together. As  
all ports support 200Mbps, the Switches can be cascaded from any port and to  
any number of switches.  
The Switches are a perfect choice for site planning to upgrade to Fast Eth-  
ernet in the future. Ethernet workgroups can connect to the Switches now,  
and change adapters and hubs anytime later without needing to change the  
Switches or reconfigure the network.  
·
·
The Switches combine dynamic memory allocation with store-and- forward  
switching to ensure that the buffer is effectively allocated for each port, while  
controlling the data flow between the transmit and receive nodes to guarantee  
against all possible packet loss.  
The Switches are an unmanaged 10/100 Fast Ethernet Switch that offers solu-  
tions in accelerating small Ethernet workgroup bandwidth.  
4
 
Other key Features are:  
·
Auto MDI/MDI-X on each port for Uplink to another switch, hub or repeater.  
·
Store and forward switching scheme capability. As the result of complete frame  
checking and error frame filtering, this scheme prevents error packages from  
transmitting among segments.  
·
·
NWay Auto-negotiation for any port. This allows for auto-sensing of speed (10/  
100Mbps) thereby providing you with automatic and flexible solutions in your  
network connections.  
Flow control for any port. This minimizes dropped packets by sending out col-  
lision signals while the port’s receiving buffer is full. Note that flow control is  
only available in half-duplex mode.  
·
·
·
Data forwarding rate per port is at wire-speed for 100Mbps speed.  
Data forwarding rate per port is at wire-speed for 10Mbps speed.  
Data filtering rate eliminates all error packets, runts, etc., per port at wire-  
speed for 100Mbps speed.  
·
·
Data filtering rate eliminates all error packets, runts, etc., per port at wire-  
speed for 10Mbps speed.  
Up to 2/8K active MAC address entry table per port with self-learning and  
table-aging for the Switch.

DC Power  
Jack:  
Power is supplied through an external AC power adapter.  
Check the technical specification section for information  
about the AC power input voltage. Since the switch does not  
include a power switch, plugging its power adapter into a  
power outlet will immediately power it on.  
Numbered  
Use these jacks to connect stations to the switch. These are  
MDI/MDI-X numbered MDI/MDI-X jacks, which mean, you can use ordi-  
Jacks:  
nary straight or crossover twisted-pair cables to connect user  
machines and servers to the switch through them.  
Note:  
1.The Switch is a power-required device, it means, the Switch will not work  
until it is powered. If your networked PCs will need to transmit data all the  
time, please consider use an UPS (Uninterrupted Power Supply) for your  
Switch. It will prevent you from network data loss.  
2.In some area, installing a surge suppression device may also help to protect  
your Switch from being damaged by unregulated surge or current to the  
Switch or the power adapter.  
LED Indicators:  
PWR  
This indicator lights green when the Switch is receiving  
power, otherwise, it is off.  
LNK/ACT  
This indicator light green when the port is connected to an  
Ethernet or Fast Ethernet station, if the indicator is blink-  
ing green, it will be transmitting or receiving data on the  
network.  
100  
This LED indicator light orange when a Fast Ethernet station  
is connected. It remains OFF, if an Ethernet station is con-  
nected.

Chapter 4  
CONNECTING THE SWITCH  
This chapter describes how to connect the Switch to your Fast Ethernet network.  
PC to Switch  
A PC can be connected to the Switch via a two-pair Category 3, 4, 5 UTP/STP straight  
cable. The PC (equipped with a RJ-45 10/100Mbps phone jack) should be connected to  
any of the 5/8 numbered port.  
The LED indicators for PC connection depend on the LAN card capabilities. If LED  
indicators are not light after making a proper connection, check the PC LAN card, the  
cable, the Switch conditions and connections.  
The following are LED indicator possibilities for a PC to Switch connection:  
The LINK/ACT and 100 LED indicators light green for hookup to 100Mbs.  
LNK/ACT lights green, while 100 LED off for hookup to 10Mbps speed.  
Hub to Switch  
A hub (10 or 100BASE-TX) can be connected to the Switch via a two-pair Category 3, 4, 5  
UTP/STP straight or crossover cable. The connection is accomplished from the hub Uplink  
(MDI-X) or normal (MDI) port to any of the Switch (MDI/MDI-X) ports:  
A. 10BASE-T Hub  
For a 10BASE-T hub, the Switch LED indicators should light up as the following:  
100 LED indicator is OFF.  
LNK/ACT LED indicator lights green.  
B. 100BASE-TX Hub  
For a 100BASE-TX hub, the Switch LED indicators should light up as the following:  
LNK/ACT,100 LED indicators light green.  
11  
 
Switch to Switches (other devices)  
The Switch can be connected to another switch or other devices (routers, bridges, etc.)  
via a two-pair Category 3, 4, 5 UTP/STP straight or crossover cable.  
When using straight or crossover cable, this is done from the any (MDI/MDIX) port of  
the Switch (Switch A) to any of the 10Mbps or 100Mbps (MDI-X) port of the other switch  
(switch B) or other devices.  
The LNK/ACT, 100 LED indicators light green for hookup to 100Mbps speed or only LNK/  
ACT light green for hookup to 10Mbps speed.  
Port Speed & Duplex Mode  
After plugging the selected cable to a specific port, the system uses auto-negotiation to  
determine the transmission mode for any new twisted-pair connection:  
If the attached device does not support auto-negotiation or has auto-negotiation  
disabled, an auto-sensing process is initiated to select the speed and set the duplex  
mode to half-duplex.

APPENDIX A  
RJ-45 PIN SPECIFICATION  
When connecting your FSD-series 10/100Mbps Ethernet Switch to another switch, a  
bridge or a hub, a straight or crossover cable is necessary. Each port of the Switch  
supports auto-MDI/MDI-X detection. That means you can directly connect the Switch to  
any Ethernet devices without making a crossover cable.

APPENDIX B  
SWITCH OPERATION  
Address Table  
The Switch is implemented with an address table. This address table composed of many  
entries. Each entry is used to store the address information of some node in network,  
including MAC address, port no, etc. The information comes from the learning process of  
Ethernet Switch.  
Learning  
When one packet comes in from any port, the Ethernet Switch will record the source  
address, port no. and the other related information in address table. These information  
will be used to decide either forwarding or filtering for future packets.  
Forwarding & Filtering  
When one packet comes from some port of the Ethernet Switch, it will also check the  
destination address besides the source address learning. The Ethernet Switch will lookup  
the address table for the destination address. If not found, this packet will be forwarded  
to all the other ports except the port which this packet comes in. And these ports will  
transmit this packet to the network it connected. If found, and the destination address is  
located at different port from this packet comes in, the Ethernet Switch will forward this  
packet to the port where this destination address is located according to the information  
from address table. But, if the destination address is located at the same port with  
this packet comes in, when this packet will be filtered. Thereby increasing the network  
throughput and availability  
Store-and-Forward  
Store-and-Forward is one type of packet-forwarding techniques. A Store-and-Forward  
Ethernet Switch stores the incoming frame in an internal buffer, do the complete error  
checking before transmission. Therefore, no error packets occurrence, it is the best choice  
when a network needs efficiency and stability.  
The Switch scans the destination address from the packet header, searches the routing  
table provided for the incoming port and forwards the packet, only if required. The fast  
forwarding makes the switch attractive for connecting servers directly to the network,  
thereby increasing throughput and availability. However, the switch is most commonly  
used to segment existing hubs, which nearly always improves overall performance.  
A Ethernet Switch can be easily configured in any Ethernet network environment to  
significantly boost bandwidth using conventional cabling and adapters.  
Due to the learning function of the Ethernet switch, the source address and corresponding  
port number of each incoming and outgoing packet are stored in a routing table. This  
information is subsequently used to filter packets whose destination address is on the  
same segment as the source address. This confines network traffic to its respective  
domain, reducing the overall load on the network.  
17  
 
The Switch performs “Store-and-forward” therefore, no error packets occur. More reliably,  
it reduces the re-transmission rate. No packet loss will occur.  
Auto-Negotiation  
The STP ports on the Switch have built-in “Auto-Negotiation.This technology  
automatically sets the best possible bandwidth when a connection is established with  
another network device (usually at Power On or Reset).  
This is done by detect the modes and speeds at the second of both device is connected  
and capable of. Both 10Base-T and 100Base-TX devices can connect with the 100Base-TX  
port in either Half- or Full-Duplex mode.  
If attached device is:  
100Base-TX port will set to:  
10Mbps  
10Mbps, no auto-negotiation
