Introduction
Intended Audience: This manual assumes that the user has a general working knowledge
of networking principles and is familiar with network systems in general.
Congratulations on the purchase of your Kingston Fast EtheRx Stackable 10/100TX
Rack-Mountable Dual Speed hub. There are three models available: KND810TX (8-port
model), KND1610TX (16-port model) KND2410TX (24-port model). The KND810TX
and KND1610TX can be used on a desktop or standard 19” rack-mount installation,
using the extended mounting brackets provided with the unit. The KND2410TX is a full
19” rack-mount unit. The Fast EtheRx Stackable 10/100TX Dual-Speed hubs conform to
IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T, and IEEE802.3 CSMA/CD
standards.
Using any combination of the dual-speed hubs, you can stack up to a
maximum of four hubs.
For ease of installation, the Fast EtheRx Stackable Dual Speed hubs offer eight (8),
sixteen (16), or twenty-four (24) UTP ports that auto-negotiate 10/100Mbps operation
and an uplink port that allows the last UTP port on the hub to support both crossover and
straight-through cabling. By default port 7 & 8 (KND810TX & KND1610TX) or port 23
& 24 (KND2410TX) are set for auto-negotiation but can be manually configured for
either 10Mbps or 100Mbps operation, using the dip switches located on the back of the
unit. Ideal for inter-connecting 10BASE-T Ethernet networks with 100BASE-TX Fast
Ethernet networks, the Fast EtheRx Dual-speed hubs can also be used as simple stand-
alone 10BASE-T or 100BASE-TX repeaters. For easy trouble-shooting, the front panel
includes a variety of diagnostic LEDs such as Power, Collision for 10Mbps and
100Mbps, 100TX, Link, and Activity status.
For the remainder of this manual, the Fast EtheRx Stackable 10/100TX Dual-Speed hubs
will be referred to collectively as the Fast EtheRx Dual-Speed hubs:
KND810TX - Fast EtheRx Stackable 8-port Rack-mountable dual-speed hub
KND1610TX - Fast EtheRx Stackable 16-port Rack-mountable dual-speed hub

Design Features
The Fast EtheRx dual-speed hub complies with the full set of repeater basic
functions as defined by IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T,
and IEEE802.3 CSMA/CD standards.
Repeater Functions
If any single port senses the start of a valid packet on its receiving line, the
dual-speed hub will re-transmit the received data to all other ports on the
network. The re-transmission of packets complies with the IEEE 802.3
specification in terms of preamble structure, voltage amplitude, and timing
characteristics.
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. 10/100Mbps selection)
Receive Jabber Protection
The dual-speed hub uses a Receive Jabber Protection scheme to ensure that the
network is not disabled due to reception of excessively long data packets.
Collision-Handling
The dual-speed hub will detect and respond to collision conditions as outlined
in the IEEE 802.3 specifications.
Error-Handling
With 100BASE-TX Fast Ethernet, the new error-handling feature prevents sub-
standard links from generating streams of false carrier and interfering with
other links.
Automatic Port Partitioning / Reconnection
If any of the ports on the dual-speed hub experience excessive collisions, or
faulty conditions, that particular port can be partitioned. Once partitioned, the
hub will continue to monitor that port. If the error conditions have been
corrected or a good data packet is received or transmitted without a collision,
the hub will automatically reconnect that port to the network.

There are two (2) separate collision LEDs for both 10Mbps and 100Mbps
segments. If a collision is detected on a 10Mbps segment, the “10” LED will
flash amber. If a collision is detected on a 100Mbps segment, the “100” LED
will flash amber. Collisions occur when 2 or more ports receive data
simultaneously
100TX (Speed-Detection) LEDs
The 100TX LED lights up when 100Mbps operation is detected. The 100TX
LED will not light up if 10Mbps operation is detected.
Link / Activity LEDs
The LINK / ACTIVITY LEDs service both 10BASE-T and 100BASE-TX
operation. A steady green light indicates that a good link has been established.
A flashing green light indicates that data is being received.
If the Link LED does not display a steady green link light, please check the

1. Make sure the power is turned on for both the PC and EtheRx hub.
2. Verify that the correct network drivers have been loaded on the PC. Some
network adapters require the drivers to be loaded to establish a proper link.
3. Make sure the correct cable type is selected.
4. Make sure the cable is wired properly and connected on both ends.
5. If steps 1 through 4 are correct, the cable may be defective or not wired
correctly. Please refer to Appendix A for pin assignments and Appendix B
for cabling guidelines.
10/100TX UTP Ports
The eight (8), sixteen (16), and twenty-four (24) 10/100TX UTP ports auto-
negotiate both 10BASE-T and 100BASE-TX connections. The speed settings
for ports 7 & 8 (on the KND810TX & KND1610TX models) and ports 23 &
24 (on the KND2410TX model) can also be manually configured to operate at
10Mbps or 100Mbps using the dip switches located on the back of the unit (see
Speed-Setting Dip Switches in the Rear Panel section). All ports like all
normal hub ports are configured as MDI-X. However, port 8 (models
KND810TX and KND1610TX) & Port 24 (model KND2410TX), support both
MDI-X and MDI port configuration.
Uplink Port
The uplink port provides cabling flexibility on UTP port no. 8 (KND810TX &
KND 1610TX models) and UTP port 24 (2410TX model) for connecting to a
workstation NIC or cascading to another hub. Although these ports have two
(2) UTP connections, MDI and MDI-X, only one port may be used.
Notes on MDI and MDI-X Ports
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, the transmitter of one device must be connected
to the receiver of the other device.

Appendix B Cabling Guidelines
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.

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 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 closets and equipment rooms.
2. COMPLIANCE – A 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 Commonly Asked Questions
I
II
100BASE-TX Fast Ethernet Repeaters
Class
vs. Class
There are currently two classes of Fast Ethernet repeaters, defined as Class
and Class II
I
.
Class
I
: in a maximum length segment topology, only one Class
I
repeater may exist between any two nodes within a single
collision domain.
Class II : in a maximum length segment topology, two Class II
repeaters may exist between any two nodes within a single collision
domain.
Will 100BASE-TX run on Category 3 cable?
No! Category 3 (CAT 3) cabling even in short lengths generates too much near
end crosstalk for 100BASE-TX networks. The IEEE 802.3u 100BASE-TX Fast
Ethernet standard requires Category 5 100 Ω UTP or 100 Ω STP which
complies with ISO/IEC 11801:1995.
What is Category 5?
Category 5 (CAT 5) is a further extension of the EIA/TIA-568 cabling system
to 100 MHz. Category 5 components (i.e., UTP trunk and patch cables,
modular plug, and patch panel, etc.) are defined by EIA/TIA-568, but with the
characterizations extended to 100 MHz by TSB-36 and TSB-40. The cable
grades are categorized as follows:
•
•
•
Category 3: up to 16 MHz
Category 4: up to 20 MHz.
Category 5: up to 100 MHz.

Appendix D Commonly Asked Questions
Category 5 Compliance vs. Category 5 Performance?
Having CAT 5 components in your network installation does not necessarily
achieve full Category
5
performance. To achieve any category-rated
performance, make sure all cabling components 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 transmissions characteristics of the Category. Category specifications
require that pair twisting be maintained to within the following distances from
the outlet termination:
•
•
•
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 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.
