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 specied 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 trafc 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
10-000039-000.indd 2004/8/27, �� 05:373

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; more-
over, 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
10-000039-000.indd 2004/8/27, �� 05:374
5
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 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.
• 2K active MAC address entry table per port with self-learning and table-aging
for the Switch.

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 net-
work 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:

Chapter 4
CONNECTING THE SWITCH
TThis 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 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 follow-
ing:
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-803PE. 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-803PE 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,
10-000039-000.indd 2004/8/27, �� 05:3712
13
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 ltering 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 ltered. 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 efciency 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 congured in any Ethernet network environment to signicantly 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 lter packets whose destination address is on the same segment as the source address. This connes network trafc to its respective domain, reducing the overall load on the network.
10-000039-000.indd 2004/8/27, �� 05:3719
20
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, no auto-negotiation 10Mbps
10Mbps, with auto-negotiation 10/20Mbps (10Base-T/Full-Duplex)
100Mbps, no auto-negotiation 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 injec-
tor 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-803PE will detect the
signal from 802.3af POE device and response to get the 48VDC power. Con-
nect 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.
10-000039-000.indd 2004/8/27, �� 05:3721
22
Please also check the PCs in the network, for some times, if one of the PCs send-
ing abnormal broadcast to the network it will also affect the overall network per-
formance. 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.
