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 / full-  
duplex 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 Full-  
Duplex 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-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-and-  
Forward, 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.

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.  
4.  
Make sure the cable is wired properly and connected on both ends.  
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.  
solid green light indicates that Full-Duplex operation has been detected.  
A
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 straight-  
through 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.  
The cascade position marked “ ” configures the last UTP port (port 5 on the  
KNS500/WG or port 8 on the KNS800/WG) as straight-through. With a  
crossover cable, this port can be used for cascading to another MDI device,  
such as a network adapter or router. With a straight-through cable, this port can  
be used for cascading to an internally-crossed 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:

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 auto-  
negotiate 100BASE-TX or 10BASE-T connections and half- or full-duplex  
mode operation. All ports, like all normal switch ports, are generally configured  
as MDI-X. However, the last UTP port (port 5 on the KNS500/WG or port 8 on  
the KNS800/WG) supports both MDI-X and MDI port configuration. Please  
refer to Cascade Switch on page 6.

Stranded filament cables are more pliable and generally targeted for patch  
cables. For proper termination, use the correct RJ-45 connector, as they  
differ for each type of cable.)  
UTP Cable Wiring  
UTP cables are wired based on one of two standard pin configurations:  
Straight-Through and Cross-Over. 100BASE-TX uses only Category-5 UTP

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  
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: 3 inches  
Category 4 maximum allowed untwisting: 1 inch  
Category 5 maximum allowed untwisting: 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.
