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.

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.

Notes on MDI and MDI-X

MDI (Media Dependent Interface) is the standard that defines the mechanical and electrical configuration of a UTP port. For any two devices to communicate with each other on the network, the transmitter of one device must be connected to the receiver of the other device. This can be achieved by using a crossover cable, or by using the MDI-Xport, which implements the crossover internally.

Port 1 through port 4 on the KNS500/WG, and port 1 through port 7 on the KNS800/WG, like all normal hub ports, are configured MDI-X.The last UTP port, port 5 on the KNS500/WG, or port 8 on the KNS800/WG, supports both port configurations, MDI andMDI-X.All NICs (Network Interface Cards) and Router ports are usually by default configured MDI. A simple illustration shows the relationship of cable types to port types:

Power Connector

The Fast EtheRx Switch gets its power from the external power adapter. Insert the power jack into the power connector located to the far right. For safety purposes, ONLY use the included power supply for proper operation. The wrong type of power supply may cause damage to both the Fast EtheRx Switch and the power supply. Please note the KNS500/WG and KNS800/WG use different power adapters.

NOTE: The power adapter DC output voltage varies depending on the model type. Be sure to use the correct power adapter. Please refer to “Appendix C Specifications” for the differences in the DC output voltage requirements of the Fast EtheRx Switches. Polarity on the power jack and DC power connector is negative(-)on the outside and positive (+) on the inside.

10/100TX UTP Ports

The Fast EtheRx Switch has either five (5) or eight (8) UTP ports that autonegotiate 100BASE-TXor10BASE-Tconnections and halforfull-duplexmode operation. All ports, like all normal switch ports, are generally configured asMDI-X.However, the last UTP port (port 5 on the KNS500/WG or port 8 on the KNS800/WG) supports bothMDI-Xand MDI port configuration. Please refer toCascade Switch on page 6.

UTP Cable Wiring Standards

There are two governmental agencies: the Electronic Industry Association (EIA) and the Telecommunications Industry Association (TIA), which set the standard for all cable wiring requirements for commercial buildings.

With the advent of 100Mb/s networking products, it is best to use higher quality CAT 5 cables like Belden or Helix as well as CAT 5-compliantpatch panels, patch cables, and connectors while following the EIA/TIA wiring standards. 100Ω UTP CAT 5 type cables use4-pairUTP wiring.

Refer to the illustrations below for 4-pairwiring using either T568A (Fig.B-1)or T568B (Fig.B-2)wiring standards. Both T568A and T568B wiring is compatible with10BASE-Tand100BASE-TXand require no special configurations, but for premise wiring, stick to one wiring standard. Mixing T568A and T568B wiring schemes may cause or lead to potential problems.

UTP Cable Rating Codes

UTP cables meet different UL-NECrequirements based mostly oncable-jacketquality. Below is an explanation of the rating codes for each cable type.

UL – The National Electrical Code (NEC), published by the National Fire Protection Association (NFPA), details advisory safety considerations for electrical wiring. NEC Article 800 Communications Cables are manufactured to meet these different cable types.

1.CMP – Cables meeting type CMP requirements are suitable for installation in ducts and plenums without the use of conduit. These cables are designed for fire resistance andlow-smokeand toxin producing characteristics.

2.CMR – Riser type cables are engineered to prevent the spread of fire from floor to floor and are suitable for vertical shaft applications.

3.CM – Cables for general building wiring. CM cables are used in areas other than plenums and risers. These cables are resistant to the spread of fire and pass the UL 1581Vertical Tray Flame Test.

4.MP, MPR &MPP – Within Article 800, theMulti-purposeCables Category, allows conditional substitutions between different cable types & are restricted by number, AWG size and stranding of the cable conductors.

Terms You Should Be Familiar With

1.BACKBONE WIRING – The physical/electrical interconnections between telecommunications wiring closets and equipment rooms.

2.COMPLIANCE – A datacomm or wiring device that meets all characteristics of a standard is said to be in compliance with that standard.

3.PREMISE WIRING – The entire wiring system on the premises, especially the supporting wiring that connects the communications outlets to the network interface jack.

4.NEAR-END CROSSTALK (NEXT) – In wires packed together within a cable, the signals generated at one end of the link can flush out the weaker signals coming back from the recipient.

Appendix D Frequently Asked Questions

What is a switch and what does it do?

Switching hubs are low-latencydevices that allow you to maximize the bandwidth of a network using concurrent access within the unit. Switches allow you to segment LANs, connect LANs of different speeds, or extend the collision domain of an existing LAN.

What’s the difference between a repeater and a switch?

A repeater is a device that extends the diameter of a network by regenerating and forwarding received Ethernet packets. It repeats incoming signals to all other ports on the device.

Like a repeater, a switch can also extend the diameter of a network. However, a switch can also extend the collision domain of a network, like bridging a 10Mbps Ethernet LAN with a 100Mbps Fast Ethernet LAN. See the illustration below. A switch can also be configured to operate in half-duplexorfull-duplexmode, whereas a repeater can only operate inhalf-duplexmode.

Switching fabric isolates each of the shared buses (repeaters) into its own collision domain.
