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.

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.

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

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.

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 Ω 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.
