Introduction

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 10/100TX Workgroup Fast Ethernet Switch. There are two models: the KNS500/WG and KNS800/WG, 5-portand8-portWorkgroup Fast Ethernet Switch, respectively. The Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch offers five (5) or eight (8) UTP(Unshielded-TwistedPair) ports thatauto-negotiatespeed detection for100BASE-TXor10BASE-Tconnections andhalf-duplex /fullduplex mode operation. The Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch provides automatic switching between 100Mbps and 10Mbps networks thus allowing100BASE-TXFast Ethernet networks to communicate with10BASE-TEthernet networks. The Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch can also be used to segment 10Mbps or 100Mbps networks. The Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch complies with IEEE 802.3u100BASE-TX,IEEE 802.3i10BASE-T,and IEEE 802.3 CSMA/CD Ethernet Standards.

The Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch supports both half and full duplex flow control to reduce the risk of data loss at congested ports. When a port is operating in half-duplexmode, the Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch implements acollision-basedbackpressure flow control mechanism. When a port is operating infull-duplexmode, the Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch implements the IEEE 802.3x flow control mechanism.

The Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch may be used in both standard desktop and workgroup installations and requires no hardware or software configuration.

To facilitate fast and easy installation and network configuration, the last UTP port has a cascade switch that supports UTP cabling in the straight through and/or crossover wiring configurations. For easy recognition of network status and troubleshooting, the front panel includes a variety of diagnostic LEDs including Power, 100TX Speed Detection, Link, Activity, Collision, and FullDuplex status.

For the remainder of this manual, the Fast EtheRx 10/100TX Workgroup Fast Ethernet Switches will be referred to collectively as the Fast EtheRx Switch.

Design Features

Design Features

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 flow 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 flow 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.

Power LED

The PWR LED indicates the power status of the Fast EtheRx Switch. The LED will light up steady green when the AC power cord is connected to the unit from a power source.

100TX Speed Detection LED

The 100TX LED will automatically light up when 100Mbps operation is detected. This LED will not light up if 10Mbps operation is detected.

Front Panel

Link / Activity LED

The LINK/ACT LED uses a single LED to display two functions. A steady green light indicates that a good link has been established, and a flashing green light indicates when data is being received or transmitted. If the LED does not display solid green indicating a good link, check the following:

1.Make sure that the power is turned on for both the Fast EtheRx Switch and the attached device.

2.Verify that the drivers for the network adapter have been loaded on the PC. Some network adapters require that the driver be loaded before establishing a proper link.

3.Make sure the cable is wired properly and connected on both ends.

4.Make sure the correct cable type has been selected.

5.If steps 1 through 4 are correct, please check the cable, as it may be defective or wired incorrectly. Replace the cable and try again. Please refer to Appendix A for Pin Assignments and Appendix B for

Cabling Guidelines.

Full Duplex and Collision LED

The FDX/COLL LED uses a single color LED to display two functions. A solid green light indicates that Full-Duplexoperation has been detected. A flashing amber light indicates that a collision has occurred inhalf-duplexmode.Full-Duplexmode isauto-negotiatedon all UTP ports.

Cascade Switch

The cascade position marked “ ” configures the last UTP port (port 5 on the KNS500/WG or port 8 on the KNS800/WG) asinternally-crossedlike all other UTP ports. By default, all repeater and switched UTP ports are generally configured as standardMDI-X,orinternally-crossedports. With a straightthrough cable, this port can be used for cascading to a standard MDI device, such as a network adapter or router. With a crossover cable, this port can be used for cascading to anotherMDI-Xdevice, such as a hub or switch.
