1 Product Overview
1Product Overview
Introduction
8× 10/100Mbps ports Fast Ethernet Switch
Live-FSH8SB Fast Ethernet Switch is an auto-sensing and auto-negotiating 10/100BASE-TX
Fast Ethernet Switch with VLAN and Priority capability. Its eight 10/100Mbps station ports
provide 10/100Mbps connections to Ethernet/Fast Ethernet network.
Live-FSH8SB’s unique switching fabric provides full wire speed for all ports. With auto-sensing,
Live-FSH8SB 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.
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-FSH8SB 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.
Active Flow Control
Live-FSH8SB 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-FSH8SB’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-FSH8SB’s switching fabric design is the perfect answer for
bandwidth enhancement solution.

Connectivity Rules
10 Mbps Connection (10BASE-T)
Ethernet connection should be configured according to the following connectivity rules:
• The maximum length for UTP cables must not exceed 100 meters from end station to a
shared-access 10BASE-T hub.
• Between any two end stations in a collision domain, there may be up to five cable segments and
four intermediate repeaters at most.
• If there is a path between any two end-stations containing five segments and four repeaters, then
at least two of the cable segments must be point-to-point link segments (e.g. 10BASE-T or
10BASE-5), while the remaining segments may be of mixed segments (e.g.: 10BASE-2 or
10BASE-5).
Twisted-pair 100Mbps Connection (100BASE-TX)
Copper-wired Fast Ethernet connection should be configured according to the following
connectivity rules:
• The maximum length for STP/UTP cable is 100 meters from end station and a shared-access
100BASE-TX hub.
• The maximum cable length is 100 meters between end station and switch/repeater; and 100
meters between switch and switch/repeater, thus making possible a maximum distance of 300
meters between two end stations.

Transmission Modes
Station Ports (10/100BASE-TX Transmission)
All 10/100Mbps station ports of Live-FSH8SB Fast Ethernet Switch utilize auto-negotiation to
determine the transmission mode for any new connection. This means, if auto-negotiation is
supported on both ends of the connection, the Switch is initiated to negotiate for one of the following
transmission modes:
• 200Mbps/FDX
• 100Mbps/HDX
• 20Mbps/FDX
• 10Mbps/HDX
LAN Micro segmentation through Switching Technology
Live-FSH8SB Fast Ethernet Switch can effectively segment your network, significantly
increasing both bandwidth and throughput. Any port on the Switch can either be attached to a hub
(i.e., shared collision domain) or serve as a dedicated link to a single network device (e.g., a
workstation). When a port on the Switch is connected to an Ethernet hub (i.e., a 10 or 100 Mbps
repeater), the bandwidth provided by that port is shared by all the devices connected to the attached
hub. However, when a port is connected to an end node or to a device that breaks up the collision
domain, e.g., another Switch, bridge or router, the attached device will have access to the full
bandwidth provided by that port.
Micro segmentation of an existing LAN can improve network latency and increase overall
performance.
Live-FSH8SB Fast Ethernet Switch uses Store-and-Forward switching to control network traffic,
thus ensuring data integrity under heavy load.
