1 Product Overview
Introduction
16× 10/100Mbps ports Fast Ethernet Switch with Per-port VLAN
function
Live-FSH16T+ Fast Ethernet Switch is an auto-sensing and auto-negotiating 10/100ABSE-TX
Fast Ethernet Switch with VLAN and Priority capability. Its sixteen 10/100Mbps station ports
provide 10/100Mbps connections to Ethernet/Fast Ethernet network.
Live-FSH16T+’s unique switching fabric provides full wire speed for all ports. With auto-sensing,
Live-FSH16T+ automatically detects the speed of the devices you plug into, and routes the
incoming data to its destination. Its auto-negotiating function allows existing devices running at
different speeds to communicate easily within the same network.
Live-FSH16T+ also supports VLAN and Priority functions as briefly described in the following
sections:
Port-based VLAN for Instant Connectivity and Workgroup
Privacy
VLAN ensures instant connectivity and workgroup privacy. Since each station port can be
configured to whichever VLAN group, it offers utmost flexibility for workgroup assignment as to
ensure workgroup privacy. For those ports that join a VLAN, it offers instant connectivity without
further configuration efforts from network administrator. Members of a same VLAN group will be
included within a same broadcast domain, and will feel exactly as they are on the same network
segment (though they might not belong to the same physical network segment).
Per-port VLAN Configuration via a selection switch
With a selection switch in the back panel, user can set the switch in operate in either 14 or
15-VLANs mode. In “14-VLANs mode”, every port is in its own VLAN group sharing Port 1 and
Port 2. In “15-VLANs mode”, every port is in its own VLAN group sharing Port 2.
Store-and-Forward Architecture against Packet Loss
When network is under heavy traffic, the shared memory buffer in the switching devices might yield
incorrect detections due to overfed memory buffer. This setback can happen either when data is
transmitted in IEEE802.3x Full Duplex or Back Pressure Flow Control mode. To solve this problem,
Live-FSH16T+ 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 an optimal value, thus guaranteeing against all possible packet
losses.

1 Product Overview
Active Flow Control
Live-FSH16T+ Fast Ethernet Switch implements in full duplex mode a flow control that is
compliant with the 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 are saturated. With this flow
control mechanism, it can be ensured that frames dropped during transmission are reduced to a
minimum.
Full Wire Speed
Live-FSH16T+’s Full Wire Speed feature provides high-end performance for departmental and
workgroup environments at a fraction of the cost of similar devices. Typically, this feature was
found only in high-end switches designed to handle huge corporate networks. With bandwidth needs
and network efficiency concerns, Live-FSH16T+’s switching fabric design is the perfect answer for
bandwidth enhancement solution.
System/Port Status Information at a Glance
There are 2 sets of LEDs on the front panel: System LEDs and Station Port LEDs.
The System LEDs consist of the Power and VLAN LEDs. Power LED shows Power On/Off status
of the switch. The VLAN LED show the VLAN configuration status
The Station Port LEDs reveal the link status, half/full duplex transmission, 10/100Mbps speed
mode and the collision status of each station port.
For detailed LED information, refer to Chapter 5, LED Indicators.
What is VLAN?
Defining VLAN
What is VLAN? Since VLAN solutions and implementations are still very vendor-specific, to define
precisely what VLANs will certainly arouse controversy. Nevertheless, most would agree that a
VLAN can roughly be equated as a broadcast domain. More specifically, VLANs can be seen as a
group of end stations, perhaps on multiple physical LAN segments, which are not constrained by
their physical location and can communicate as if they were on a common LAN.
There are several ways to define VLAN membership: port grouping, frame tagging, MAC-layer
grouping, network-layer grouping, IP multicast grouping, etc. Live-FSH16T+ utilizes
port-grouping (port-based VLAN) for the implementation of VLAN in your network.
Port-based VLAN
Live-FSH16T+ simplified the VLAN setup by implementing the most common used VLAN
configuration with a selection switch. The VLAN mode of Live-FSH16T+ allows users to put each
port in separate VLAN groups while able to share common resources. In VLAN mode, each port
is in its own VLAN group with Port 8 and Port 16 as sharing ports. The sharing ports are ports that
are shared by all VLAN groups for common resources such as Internet connection, servers, or
connection to another switch.
