Compliance Standards

The Fast EtheRx Switch complies with the 10/100Mbps functions as defined by IEEE802.3u 100BASE-TX,IEEE802.3i10BASE-T,and IEEE802.3 CSMA/CD Ethernet standards.

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.10/100BASE-TXselection,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

The Fast EtheRx Switch implements a collision-basedflow control mechanism that reduces the risk of data being lost at the congested ports. This is accomplished by forcing a collision with the data frames on all ports once thefree-bufferqueue has reached thepre-setminimum.

Hardware Installation

Before you begin installing network cables, please take a few moments to familiarize yourself with Fast EtheRx Switch. The functions on the front and rear panels are illustrated in the following sections.

Fig. 1-KNS1600/RFront Panel

Front Panel

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 and the power switch on the unit has been turned on.

100BASE-TX(100TX) LED

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

LINK/ACT LED (for both 10 and 100Mbps)

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 forCabling Guidelines.

Full Duplex and Collision LED

The FDX/COLL LED uses a dual 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. FullDuplex mode isauto-negotiatedon all UTP ports.

UTP Ports

The Fast EtheRx Switch has sixteen (16) 10/100Mbps UTP ports that autonegotiate 10/100BASE-TXconnections and halforfull-duplexmode operation. The last UTP port has twoRJ-45port connectors for support of UTP cabling in the crossover orstraight-throughwiring configuration. Only one of the two ports may be utilized.

The RJ-45port markedis internally crossed like all other UTP ports. By default, all repeater and switched UTP ports are generally configured as standardMDI-X,or internally crossed ports. With astraight-throughcable, 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.

Front Panel

The following diagrams show the relationship between cable type and which UTP port connector to use. To verify the pin wiring of your UTP cable, see

“Appendix A Pin Assignments.”

Using a Straight-ThroughCable

Use the port labeled when connecting to a network card or other MDI device.

Use the port labeled when connecting to a hub or other MDI- X device.

Using a Crossover Cable

Use the port labeled when connecting to a network card or other MDI device.

Use the port labeled when connecting to a hub or other MDI- X device.

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.

Ports 1 through 15, like all normal hub ports, are configured as MDI-X.Port 16 supports both MDI andMDI-Xconfigurations. All NICs (Network Interface Cards) and Router ports are usually by default configured MDI.

Note: Do not use both ports labeled port 16, only one connection can be used.

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.

PJ 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.
