Introduction

8-Port 10/100 Mbps Auto-sensing Dual Speed Switch

Live-FSH8R Fast Ethernet Switch is an 8-port auto-sensing a nd auto- negotiating Dual-speed Fast Ethernet Switch with one Uplink port. It

is designed with a view to provide SOHO users with maximum benefit to work in a SOHO LAN environment. All of its 8 RJ-45 station ports

support Dual Speed with auto-sensing and auto-negotiating functions. The Uplink port is provided for connection with another switch or hub. All its 8 station ports can automatically a da pt to data rate s ranging from 10 Mbps (Ethernet half-duplex mode) to 200 Mbps (Fast Ethernet full-duplex mode). With auto-sensing function, Live-FSH8R automatically detects the speed of the devices you plugged 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 unnecessary or expensive upgrade.

Store-and-Forward Ar chitectur e against Pa cket Loss

It is recognized that when network is under heavy traffic, the shared memory buffer in the switching devices might yield incorrect detection due to an overfed memory buffer. This drawback in transmission sometimes can ha ppen either when data be ing transmitted in IEEE802. 3x Full Duplex or Back Pressure Flow Control mode. To amend this problem, Live-FSH8R 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.

1-2 Introduction

Active Flow Control

Live-FSH8R 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 a n optional Ba ck Pre ssure 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 tra nsmission are reduced to a minimum.

Non-blocking Wire Speed

Live-FSH8R’s non-blocking cross-bar matrix architecture provides high-end performance for departmental and workgroup environments at a fraction of the cost of similar devices. Typically, this type of architecture is found only in high-end switches designed to handle huge corporate networks. With bandwidth needs and network efficiency concerns, Live-FSH8R’s switching fa bric de sign is the perfect answer for solution. You can take advantages of this high bandwidth performa nce capa ble of running your data-throughput at excellent speed. And you’ll appreciate the efficiency and smoothne ss that is brought to you by this new dimension of Live-FSH8R’s switching architecture.

Broadcast Storm Control

Live-FSH8R is capable of broadcast storm control. A broadcast storm occurs when a large number of broadcast packets are received from a given port. Forwarding these packets can cause the network to slow down or time out. Broadcast storm control defines threshhold for the number of broadca st pa ckets that can be rece ived from ea ch port bef ore forwarding is blocked. Specifically , each port will drop broadca st packet (the Destination ID, or DID, is f f f f ff f f ff f f) after rece iving continuous 64 broadcast packets. The counter will be reset to 0 every 800ms or when receiving any non-broadca st packet (DID is not ff ff ff ff f f f f).

Perfect Companion f or LAN Users in SOHO Scenario

Live-FSH8R provides f ollowing featur es which you’ll find especially suitable for SOHO networking. Users who work in a SOHO envir onment will definitely come to appreciate its numer ous adva ntages:

Compact size making more “elbowroom” on your SOHO Desktop

The palm-size Live-FSH8R Fast Ethernet Switch is designed to perfectly fit into you SOHO environment. Its compact size will fit snugly onto your desktop, and provides more “elbowroom” for your working space. In a SOHO environment, it not only saves your money but also your precious space.

Easy Plug-and-Play costs SOHO users No Network Management Effort

Live-FSH8R Fast Ethernet Switch fully complies with the IEEE 802.3 standard for 10BASE-T network and the IEEE802.3u standard for 100BASE-TX network. And it takes SOHO users almost no effort to install it in a mixed 10M/100Mbps Ethernet/Fast Ethernet environment. Simply plug in the power and connect other devices to its ports, and you just complete its installation. Furthermore, the Switch operates in a protocol-independent manner, eliminating the overhead for management software. With its easy Plug-and-Play feature, Live- FSH8R Fast Ethernet Switch costs SOHO users virtually no effort to install and run.

Very Cost-effective for SOHO Networking

Live-FSH8R Fast Ethernet Switch is the best choice for a cost- effective solution for SOHO users to expand, connect or upgrade its existing 10 Mbps Ethernet to 100 Mbps Fast Ethernet network. With

the implementation of Live-FSH8R 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.

LED Information helps users monitor their network status

The LED indicators on the front pa nel show releva nt inf ormation of your network status. SOHO users can get insta nt inf ormation from the front-pa nel LEDs: The Power LED indicates the Power On/Off status. The DIAG LED give s users the functional status of the Switch as a preliminary diagnostic to warn for possible hardware failure. The ENLOOP LED of a network loop when the switch’s loop detection function is enabled. Ea ch Link/Act LED indicates the linking a nd receiving/ tra nsmitting status of each port, while FDX/Col LED shows the half-/full-duplex transmission status and the collision status of your port. The 100 M LED indicates whether the connection is running at 100 Mbps mode. For detailed LED information, plea se

What is 10/100 Mbps Dual-Speed Switching?

Current expa nsion 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 a n integral extension of Fa st Ethernet. It provide s not only the 100Mbps high-speed “pipeline” for carrying aggregated 10Mbps traffic, but also the necessary bridging between the 10BASET a nd 100BASE-TX MAC f ormats. Fast Ethernet combined with the Switching technology offers an adequate bandwidth to satisfy the dem and 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 flexibility a nd 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-FSH8R Fast Ethernet Switch is your perfect solution to solve network congestion.
