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.

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.

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.

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.
Download from Www.Somanuals.com. All Manuals Search And Download.
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

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.
