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 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 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 required make routers  
relatively impractical. Today switches are an ideal solution to most kinds of local area network  
congestion problems.  
Power over Ethernet Technology  
The Switch also supports IEEE802.3af in-line power technology. Power over Ethernet Technology  
is using the un-used UTP wire to transmit the power over the Cat-5 UTP to the remote end-node.  
Follow the IEEE802.3/802.3u Ethernet standard, 100Base-TX and 10Base-T will only use 2-pair of  
the UTP cable for data transmission and receiving (refer to Appendix B for more). And Power over  
Ethernet, however, will used the un-used 2-pair of UTP Cat. 5 cable for power transmission. The  
power transmission either can be a direct current without any detection/ protection or can also  
deploy the new standard IEEE802.3af.  
Two devices required in this technology, injector and splitter. The injector combine the Ethernet  
signal and 48VDC currents through UTP cable to the remote end. And splitter split out the two  
things to the device, DC power to turn on the device and others for data sending / receiving.  
IEEE802.3af uses the protection circuit to detect the support features of remote end-node in a very  
short time. If the remote-end reply the injector with 802.3af supported signal, the injector will then  
provide the DC current over the wire to power on the Switch. Otherwise, the Switch will never be  
turned on.  
Features  
The Switch were designed for easy installation and high Performance in an environment  
where traffic on the network and the number of user increase continuously.  
The Switch with their small, compact size was specifically designed for small to middle  
workgroups. The Switch can be installed where space is limited; moreover, it provides  
immediate access to a rapidly growing network through a wide range of user-reliable  
functions.  
The Switch is ideal for deployment with multiple high-speed servers for shared bandwidth  
 
10Mbps or 100Mbps workgroups. With the highest bandwidth 200Mbps (100Mbps  
full-duplex mode), any port can provide workstations with a congestion-free data pipe for  
simultaneous access to the server.  
The Switch is expandable by cascading two or more switches together. As all ports support  
200Mbps, the Switch can be cascaded from any port and to any number of switches.  
The Switch is a perfect choice for site planning to upgrade to Fast Ethernet in the Ethernet  
workgroups can connect to the Switch now, and change adapters and hubs anytime later  
without needing to change the Switch or reconfigure the network.  
The Switch support IEEE802.3af, which can easily install the Switch in any place where AC  
adapter is not required. Through the UTP wire, the power of the Switch can be managed  
from the central/backbone and also without fear of power shutdown.  
The Switch 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 Switch is an unmanaged 10/100 Fast Ethernet Switch that offers solutions in  
accelerating small Ethernet workgroup bandwidth.  
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 collision 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.  
2K active MAC address entry table per port with self-learning and table-aging for the Switch.

Please refer to the LED panel section for detailed information about each of the switch’s LED  
indicators.  
 
 
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.  
POE  
The Switch supports two power systems, 12VDC or powered from POE. Port  
# 1 supports 802.3af in-line power. Either power system can be deployed to  
the Switch at a time. And 12VDC will not active if POE port and POE power is  
in use.  
Numbered  
MDI/MDI-X  
Jacks:  
Use these jacks to connect stations to the Switch. These are numbered  
MDI/MDI-X jacks, which mean, you can use ordinary 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 either through POE port or DC 12V. 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 if  
DC12V power is in use.  
3. Consult the network administrator for the information of 802.3af Power over Ethernet.  
Port#1 only accept 802.3af power supply, connect with any other non-standard 802.3af  
equipments to it may cause the Switch malfunction.  
LED Indicators:  
PWR/PoE This indicator lights green when the Switch is receiving 12VDC power and lights  
orange when receiving 48VDC PoE 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 blinking green, it will be transmitting or receiving data on the  
network.  
 
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  
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.  
 
 
Powered from POE hub / switch  
Port#1 of the Switch support IEEE802.3af power over Ethernet, you can direct connect the Switch  
to the 802.3af in-line power devices like 802.3af POE hub, Ethernet Switches that with 802.3af  
POE Ethernet port.  
A Category 5 UTP cable with 4-pair wire is required from POE hub to your FSD-504PE. Once the  
Switch connect with POE device like PLANET POE-150, 1-Port 802.3af injector or POE hub, the  
“POE” indicator of the Switch will turns on to indicate it get the power from the remote POE injector.  
And the Switch will start its POST (Power on self test) process and start to work.

Getting the power from central POE injector, the FSD-504PE shall works without fear of remote  
power breakdown. As soon as the local PCs also installed with UPS, it shall guarantee the true  
un-interrupted network accessing.  
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. However, powered from POE port  
 
will require four-pair Cat 5/5e UTP/STP 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 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.  
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  
10Mbps, with auto-negotiation  
100Mbps, no auto-negotiation  
10/20Mbps (10Base-T/Full-Duplex)  
100Mbps  
100Mbps, with auto-negotiation 100/200Mbps (100Base-TX/Full-Duplex)  
 
Appendix C Troubleshooting  
1. Power LED does not turns on?  
Ans:  
The Switch supports two power sources, 12VDC and 802.3af, please check which kind of  
power system deployed.  
a) Powered from POE: please check with network administrator if the POE injector device  
is complied with 802.3af standard and well connected to port#1 of the Switch with 4-pair  
UTP cable within 100 meters. FSD-504PE will detect the signal from 802.3af POE device  
and response to get the 48VDC power. Connect with non-802.3af complied injector to  
port#1 could damage the Switch permanently  
b) Powered from 12VDC: the Switch supports 12VDC AC adapter. Please check the AC  
adapter complies with 12V DC output. Incorrect DC power to the Switch, higher voltage  
could damage the Switch, and lower voltage will not power on the Switch.  
2. POE LED always blinking and can not boot up the Switch?  
Ans:  
The Switch only requires one power source, i.e. from POE or from 12V DC. By default, POE  
will be the first priority. However, if the POE device cannot provide sufficient power from the  
injector, or 12V DC power is just removed from the DC-jack, the “POE” LED will blink.  
a) Powered from POE: please consult the network administrator if the POE device can  
provide the sufficient current or not.  
b) Powered from 12VDC then POE: please remove all the power connection, i.e. both DC  
plug and port#1. And re-connect the port#1 to force the Switch detect its power system  
again.  
3. Performance is not good?  
Ans:  
Please check the duplex setting of the Switch and the connected device, if the connected  
device does not support Auto-Negotiation, please set the device to forced half-duplex mode.  
Otherwise, the performance could be poor due to the incorrect duplex mode setting.  
Please also check the PCs in the network, for some times, if one of the PCs sending  
abnormal broadcast to the network it will also affect the overall network performance. You  
can check the LED of the switch to diagnose the symptom. Remove all the connection and  
plug-in one by one, if the LNK/ACT LED is blinking all the time (never stop), please isolate  
this PC and see if the performance will goes back to normal if the reset PCs are connected  
back to the switch.
