Introduction 1
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-port and 8-port Workgroup Fast Ethernet Switch, respectively. The Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch offers five (5) or eight (8) UTP (Unshielded-Twisted Pair) ports that auto-negotiate speed detection for 100BASE-TX or 10BASE-T connections and half-duplex / full­duplex mode operation. The Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch provides automatic switching between 100Mbps and 10Mbps networks thus allowing 100BASE-TX Fast Ethernet networks to communicate with 10BASE-T Ethernet 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 802.3u 100BASE-TX, IEEE 802.3i 10BASE-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-duplex mode, the Fast EtheRx 10/100TX Workgroup Fast Ethernet Switch implements a collision-based backpressure flow control mechanism. When a port is operating in full-duplex mode, 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.

4 Design Features
Design Features
Switching Function
The Fast EtheRx Switch is basically designed to bridge Standard 10BASE-T Ethernet networks to 100BASE-TX Fast Ethernet networks and to segment 10Mbps or 100Mbps network segments.
Auto-Negotiation
Auto-Negotiation provides 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-T selection, half- / full-duplex mode operation, etc.)
Full-Duplex
Full-Duplex transmission means that dedicated inbound and outbound channels are established for bi-directional transmission of data. This allows the collision detection mechanism (CSMA/CD) to be by-passed, thus decreasing transmission delay normally caused by listening, collisions, and packet resends when operating in half-duplex mode.
Store-and-Forward Switching
The Fast EtheRx Switch uses a packet-forwarding method called Store-and­Forward, which minimizes the re-transmission of 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-duplex mode the Fast EtheRx Switch implements a collision-based backpressure 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 the free-buffer queue has reached the pre-set minimum.
In full-duplex mode 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 the pre-set minimum.

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-Duplex operation has been detected. A flashing amber light indicates that a collision has occurred in half-duplex mode. Full-Duplex mode is auto-negotiated on 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) as internally-crossed like all other UTP ports. By default, all repeater and switched UTP ports are generally configured as standard MDI-X, or internally-crossed ports. 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 another MDI-X device, 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-X port, 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 and MDI-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:

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-compliant patch panels, patch cables, and connectors while following the EIA/TIA wiring standards. 100 UTP CAT 5 type cables use 4-pair UTP wiring.
Refer to the illustrations below for 4-pair wiring using either T568A (Fig. B-1) or T568B (Fig. B-2) wiring standards. Both T568A and T568B wiring is compatible with 10BASE-T and 100BASE-TX and 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-NEC requirements based mostly on cable-jacket quality. 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 and low-smoke and 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, the Multi-purpose Cables 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-latency devices 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-duplex or full-duplex mode, whereas a repeater can only operate in half-duplex mode.
Switching fabric isolates each of the shared buses (repeaters) into its own collision domain.

Category 5 Compliance vs. Category 5 Performance?
Using CAT 5 cabling in your network installation does not necessarily achieve full Category 5 performance. To achieve any category-rated performance, make sure all cabling components, including modular plugs, trunk cables, and patch panels, are at least of the minimum category required.
To achieve full CAT 5 performance, all components must be CAT 5 compliant and terminated properly according to EIA/TIA-568 TSB-36 and TSB-40 guidelines.
What are the Guidelines for Proper Termination?
It is important to maintain the twists of the cable as close to the termination on the outlet as possible, to avoid NEXT (Near End Cross Talk) and to maintain the transmission characteristics of the Category. Category specifications require that pair twisting, at the point of termination, not exceed the following maximums:
Category 3 maximum allowed untwisting:
Category 4 maximum allowed untwisting:
Category 5 maximum allowed untwisting:
3 inches 1 inch 1/2 inch
Can I mix CAT 3 and CAT 5 cabling in the same building?
Yes, but keep in mind, you will not have CAT 5 performance. It is a good idea to keep the lines separated, physically and by color, when installing any new lines, use CAT 5 UTP cabling only.
Can a Four-Pair CAT 5 cable support two 100BASE-TX devices?
Although only two pairs are used in the standard four-pair CAT 5 UTP cable, it is not recommended because it exceeds the specifications outlined by IEEE
802.3u.
