Product Overview
Introduction
16-port 10/100 Mbps Fast Ethernet Switch
Live-FSH16T Fast Ethernet Switch is a 16-port auto-sensing and auto-negotiating
Dual-speed Fast Ethernet Switch with Port Priority function. All of its 16 RJ-45 station
ports support Dual Speed with auto-sensing and auto-negotiating functions. All 16 station
ports can automatically adapt to data rates ranging from 10 Mbps (Ethernet half-duplex
mode) to 200 Mbps (Fast Ethernet full-duplex mode).
Live-FSH16T also features port priority function that is implemented via built in
priority port (port 5, 6, 7 and 8). You can instantly utilize priority function by
plugging into these ports without further configuration. Priority port can ensure high
priority traffic to be delivered efficiently, even when during bursts of high traffic load.
Traffic such as voice data and video (services which are streaming) are thus prioritized,
helping steady picture and sound quality. Please refer to the Using Priority Ports section in
Chapter 4.
The Uplink port is provided for connection with another switch with straight-through
cable. With its Uplink port, you can connect two switches together to reach a maximum of
48 ports. With auto-sensing function, Live-FSH16T Fast Ethernet Switch automatically
detects the speed of the devices you plug into, and routes the incoming data to its
destination. Its auto-negotiating function also allows existing devices with different speeds
to communicate easily within the same network.
With these advantages, you have no further costs for hardware investment in unnecessary
or expensive upgrade.
Easy Plug-and-Play
Live-FSH16T Fast Ethernet Switch fully complies with the IEEE802.3 standard for
10BASE-T network and the IEEE802.3u standard for 100BASE-TX network. And it takes
users almost no effort to install. Simply plug in the power and connect devices to its ports
and you just complete its installation. With its easy Plug-and-Play installation procedure,
Live-FSH16T Fast Ethernet Switch costs you virtually no effort to install and run.
Cost-effective for LAN Users
Live-FSH16T Fast Ethernet Switch is your best choice for a cost-effective solution to

9
expand, connect or upgrade your existing 10 Mbps Ethernet to 100 Mbps Fast Ethernet
network. With the implementation of Live-FSH16T Fast Ethernet Switch, it means that
your existing 10 Mbps Ethernet network can be extended to Fast Ethernet 100 Mbps speed
at very effective costs.
Store-and-Forward Architecture against Packet Loss
It is recognized that when network is under heavy traffic, the shared memory buffer in the
switching devices might yield incorrect detections due to an overfed memory buffer. This
drawback in transmission can happen either when data being transmitted in IEEE802.3x
Full Duplex or Back Pressure Flow Control mode. To amend this problem, Live-FSH16T
Fast Ethernet Switch utilizes a fixed memory buffer allocation with Store-and-forward
transmission to ensure an effective buffer allocation for each port. Store-and-forward
transmission controls data flow from transmitting to receiving nodes with the receiving
buffer threshold adjusted to optimal value, guaranteeing against all possible packet losses.
Active Flow Control
Live-FSH16T Fast Ethernet Switch implements in full duplex mode a flow control which
is compliant to IEEE 802.3x standard. While in half duplex mode, it employs an optional
Back Pressure Flow Control to stall the incoming data when port buffers being saturated.
With this flow control mechanism, it can be ensured that frames dropped during
transmission are reduced to a minimum.
Port Status Information at a Glance
The LED indicators on the front panel show relevant information of your network status.
Power LED indicates the Power On/Off status. Each Link/Rx LED indicates the linking
and receiving status of each port, while FDX/Col LED shows the half-duplex/full-duplex
transmission status and collisions within network. 100 M LED indicates the connection is
running at 100 Mbps mode. For detailed LED information, please refer to Chapter 5, LED
indicators.
What is 10/100 Mbps Dual-Speed Switching?
Current expansion of multimedia usage on the network, together with the new wave of
distributed Client/Server applications, creates a much higher demand for bandwidth and
tighter integration of clients and servers. The legacy shared-access 10Mbps Ethernet
technology can no longer provide adequate bandwidth and predictable response time to the
new workgroup environment.
10/100 Switching is an integral extension of Fast Ethernet. It provides not only the
100Mbps high-speed “pipeline” for carrying aggregated 10Mbps traffic, but also the
necessary bridging between the 10BASET and 100BASE-T MAC formats.
Fast Ethernet combined with the Switching technology offers an adequate bandwidth to
satisfy the demand of local workgroups. It also provides a high-speed link to carry local
network traffic elsewhere within a network. Ethernet switching technology dramatically
boosts the total bandwidth performance of a LAN network. It also furnishes configuration

10
flexibility and bandwidth adaptability for the local workgroups where the majority of
workload is generated by business applications.
Switching function further eliminates the congestion problem inherent to the
contention-based CSMA/CD protocol, thereby improving predictable response time under
heavy load. While in the past, this network congestion could only be alleviated by much
more expensive routing technology. With the implementation of switching technology,
Live-FSH16T Fast Ethernet Switch is your perfect solution to solve network congestion.
What is Priority Queuing?
Priority Queuing is a method of ensuring that high priority traffic gets delivered efficiently,
even when during bursts of high traffic load. In this way, traffic such as voice data and
video (services which are streaming) are prioritized, helping steady picture and sound
quality.
If you have any plans to implement network telephony or any sort of video conferencing,
streaming video/audio or any real-time applications on your network you will need
Live-FSH16T for priority queuing. The benefit of priority queuing is that it can
dramatically improve the quality of priority services on the network. If priority queuing is
not implemented then the quality of these services will depend entirely on the load on your
network. If network traffic is high, the service will not work properly.
