Introduction

Intended Audience: This manual assumes that the user has a general working knowledge of networking principles and architecture and is familiar with network systems in general.

Congratulations on the purchase of your new Kingston Fast EtheRx 10/100BASE-TXRack-MountableFast Ethernet Switch. There are three models available, theKNS1650/R, theKNS2450/R and theKNS3250/R,16-ports,24-portsand32-ports,respectively. The Fast EtheRx Switch is ahigh-performance10/100BASE-TXswitch ideal for thesmall-to-mediumbusinesses. The Fast EtheRx Switch has sixteen (16),twenty-four(24) orthirty-two(32) UTP ports (depending on model) thatauto-negotiatespeed detection for10/100BASE-TXandhalf-duplex /full-duplexmode operation. The Kingston Fast EtheRx Switch allows standard10BASE-TEthernet networks to communicate with100BASE-TXFast Ethernet networks and to segment both 10Mbps and 100Mbps networks. The KNS1650/R, KNS2450/R, and KNS3250/R switches also provide additional features such as VLAN, link trunking, broadcast storm control, secure mode traf cltering and ow control. The Fast EtheRx Switch complies with IEEE802.3u100BASE-TX,IEEE802.3i10BASE-T,IEEE 802.3x and IEEE802.3 CSMA/CD Ethernet Standards.

The Fast EtheRx Switch may be used in both standard desktop and 19” rackmount installations (using the mounting brackets provided with the unit). For easy recognition of network status and troubleshooting, the front panel includes a variety of diagnostic LEDs including Power, 100TX Speed Detection, Link, Receive, Transmit, Collision, and Full-Duplexstatus.

For the remainder of this manual, the KNS1650/R, KNS2450/R, and KNS3250/R will be referred to collectively as the Fast EtheRx Switch.

4 Design Features

Design Features

VLAN

VLAN is short for Virtual Local Area Network, and is generally de ned as a broadcast domain. It can be viewed as a group of end nodes which can communicate with each other even though they may be located on different physical network segments.

The Fast EtheRx switch provides a simple solution to protect your network against broadcast storming by creating segments based on Layer 2 Ethernet information. As a result, each group of stations connected to a seperate segmented port form an isolated Broadcast Domain. In a switched network environment, a broadcast packet or an unknown destination MAC address packet will broadcast to ALL ports, which can decrease the entire network system performance dramatically. By grouping ports into VLANs, broadcast packets will only be sent to the ports within the same VLAN without effecting the traf c of the ports outside of the VLAN. Broadcast sharing ports can be used to connect servers and other common services, such as Internet access, that are used by all the stations connected to the different segmented ports.

Typically users are grouped according to similar characteristics such as a common business function or a common protocol. A single switch may have several independent VLANs within it.

Link Trunking

Link trunking is basically a method of treating multiple physical links as a single logical link. By grouping ports into a trunk, you can increase the available bandwidth between switches or servers. Multiple lower speed links can be grouped into a single higher speed link. For example, four full-duplex100Mbps link, such as ports 1 through 4, can be grouped as a single 800Mbps link as Trunk 1.

Switching Function

The Fast EtheRx Switch is basically designed to bridge Standard 10BASE-TEthernet networks to100BASE-TXFast Ethernet networks and to segment 10Mbps or 100Mbps network segments.

Auto-Negotiation

Auto-Negotiationprovides the means of automatically establishing a link by detecting the link capabilities of the connected device on the network to select the best operational mode available (i.e.100BASE-TX/10BASE-Tselection,half- /full-duplexmode operation, etc.)

Full-Duplex

Full-Duplextransmission means that dedicated inbound and outbound channels are established forbi-directionaltransmission of data. This allows the collision detection mechanism (CSMA/CD) to beby-passed,thus decreasing transmission delay normally caused by listening, collisions, and packet resends when operating inhalf-duplexmode.

Store-and-ForwardSwitching

The Fast EtheRx Switch uses a packet-forwardingmethod calledStore-and-Forward, which minimizes there-transmissionof faulty data packets. This means that the Fast EtheRx Switch can store the incoming frame in an internal buffer and check the packet for errors before sending it out to the destination port. If the frame does contain errors, it will be discarded and then retransmitted.

Flow Control

In half-duplexmode the Fast EtheRx Switch implements acollision-basedbackpressure ow control mechanism that reduces the risk of data loss at congested ports. This is accomplished by forcing a collision with the data frames on all ports once thefree-bufferqueue has reached thepre-setminimum.

In full-duplexmode the Fast EtheRx Switch implements the IEEE 802.3x ow control mechanism. This is accomplished by sending a PAUSE packet on a port when the number of buffers allocated to this port exceeds thepre-setminimum.
