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
10/100BASE-TX 19” Rack-Mountable Fast Ethernet Switch. There are two
models: the KNS800/R and the KNS1600/R, 8-port and 16-ports respectively.
The Fast EtheRx Switch is a high-performance 10/100BASE-TX switch ideal
for the small-to-medium businesses. The Fast EtheRx Switch has eight (8) or
sixteen (16) UTP ports that auto-negotiate speed detection for 10/100BASE-TX
and half-duplex / full-duplex mode operation. It is basically designed to allow
Standard 10BASE-T Ethernet networks to communicate with 100BASE-TX
Fast Ethernet networks and to segment both 10Mbps and 100Mbps networks.
The Fast EtheRx Switch complies with IEEE802.3u 100BASE-TX, IEEE802.3i
10BASE-T, and IEEE802.3 CSMA/CD Ethernet Standards.
The Fast EtheRx Switch may be used in both standard desktop and 19” rack-
mount installations (using the mounting brackets provided with the unit) and
requires no hardware or software configuration.
The last port on the Fast EtheRx Switch has two RJ-45 connectors to support
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, Receive, Transmit, Collision, and Full-Duplex status.
For the remainder of this manual, the KNS800/R and KNS1600/R will be
referred to collectively as the Fast EtheRx Switch.

Design Features
Compliance Standards
The Fast EtheRx Switch complies with the 10/100Mbps functions as defined by
IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T, and IEEE802.3 CSMA/CD
Ethernet standards.
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. 10/100BASE-TX 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
The Fast EtheRx Switch implements a collision-based flow 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 the free-buffer queue has
reached the pre-set minimum.

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/RX LED (for both 10 and 100Mbps)
The LINK/RX 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. 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.
TX LED (Model KNS800/R Only)
The TX LED displays a flashing green light when data is transmitted. A flash
may be longer or shorter depending on the length of the data packet being
transmitted.
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-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.
UTP Ports
Depending on the model, the Fast EtheRx Switch has eight (8) or sixteen (16)
10/100Mbps UTP ports that auto-negotiate 10/100BASE-TX connections and
half- or full-duplex mode operation. The last UTP port has two RJ-45 port
connectors for support of UTP cabling in the crossover or straight-through
wiring configuration. Only one of the two ports may be utilized.
The RJ-45 port marked “MDI-X” is 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.
The RJ-45 port marked “MDI” is a standard straight-through port. 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
repeater, or hub.

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.

Appendix B Cabling Guidelines
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.
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
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.

Appendix D Frequently Asked Questions

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.
