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 Kingston EtheRx WorkGroup (WG)
series 100BASE-TX Fast Ethernet hubs. There are two models available in this
series: KNE4TX/WG, which is the 4-Port model, and KNE8TX/WG, which is
II
the 8-Port model. The EtheRx Workgroup series hubs are Class
repeaters
that conform to IEEE 802.3u 100BASE-TX standards. Please refer to
II
Appendix D for further information on Class
repeaters.
The EtheRx Workgroup hubs support up to four (4) or eight (8) UTP
(Unshielded Twisted-Pair) ports for 100BASE-TX network connections. Both
models include a cascade switch on the last UTP port (Port 4 or Port 8) which
supports both straight-through and crossover cable types. The UTP ports use
dual-color LEDs to show three states of operation: link, activity and
partition/error. The EtheRx hubs also include a collision LED for collision
detection and five (5) utilization LEDs to display the level of network traffic in
percentages of the total available bandwidth.
For the remainder of this manual, the KNE4TX/WG (4-port model) and the
KNE8TX/WG (8-port model) hubs will be referred to as the EtheRx hubs.

Design Features
The EtheRx hub complies with the full set of repeater basic functions as
defined by IEEE 802.3u. These functions include all Repeater Functions,
Signal Regeneration, Receive Jabber Protection, Collision-Handling, Error-
Handling, and Auto Partitioning/Reconnection.
Repeater Functions
If any single port senses the start of a valid packet on its receiving line, the
EtheRx hub will re-transmit the received data to all other ports on the network.
The re-transmission of packets complies with the IEEE 802.3u specification in
terms of preamble structure, voltage amplitude, and timing characteristics.
These timing regenerations prevent cumulative signal loss, jitters, and
distortion caused by network cabling, thus allowing the EtheRx hubs to be
II
cascaded to other 100BASE-TX Class
repeaters.
Receive Jabber Protection
The EtheRx hub provides a Receive Jabber Protection scheme to ensure that
the network is not disabled due to reception of excessively long data packets.
This protection scheme will automatically interrupt the receiver if the EtheRx
hub has been continuously receiving for more than 65,536-bit times.
Collision-Handling
The EtheRx hub will detect and respond to collision conditions as outlined in
the IEEE 802.3u specifications.
Error-Handling
The 100BASE-TX standard uses an improved method of error-handling called
block coding. With 100BASE-TX Fast Ethernet, the new error-handling
feature prevents substandard links from generating streams of false carrier and
interfering with other links.
Automatic Port Partitioning/Reconnection
If any of the ports on the EtheRx 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 without a collision, the hub will automatically
reconnect that port to the network.

Utilization LEDs
The five Utilization LEDs display the rate of network traffic in percentages of
the total available bandwidth. The amount of data traffic is measured in frames
per second (FPS), then calculated into percentage values: 1%, 12%, 25%, 50%,
and > 60%. The appropriate LED will light up based on network activity.
Collision LED
If a collision is detected on the network, the Collision LED will flash amber. A
collision occurs when the hub receives data from two or more nodes
simultaneously.
4 or 8 UTP Port LEDs
The LINK/ACTIVITY/PARTITION LEDs use two colors to display three
states of operation for the 4 or 8 UTP ports. If a good link is established on any
given port, the LED will light up steady green, indicating a valid network
connection between the network node and the hub. If the LED does not
display solid green indicating a good link, check the following:
1.
2.
Make sure the power is turned on for both the PC and EtheRx
hub.
Verify the network adapter has loaded its drivers from the PC.
Some network adapters require the drivers to be loaded to
establish a proper link.
3.
4.
Make sure the correct cable type is selected.
Make sure the cable is wired properly and connected on both
ends.
5.
If steps 1 thru 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.
A flashing green light indicates when data is being received. A flashing amber
light indicates one of the following occurences:
1.
2.
A port has been partitioned due to an excessive number of
collisions or
A port has encountered errors due to invalid packets or jabber
conditions.

Cascade Switch
The Cascade Switch provides cable wiring flexibility on the last UTP Port (i.e.,
Port 4 or Port 8) for connecting to a workstation or cascading to another hub.
By default, the last UTP port is set to “Crossover” (left side) as a standard,
internally-crossed port, or MDI-X port. Depending on the wiring of your UTP
cable (normally “Straight-Through”), the port is used to connect a workstation.
II
For cascading to another Class
repeater using a straight-through cable,
move the Cable Switch to “Straight-Through” (right side). If a crossover UTP
II
cable is used to cascade to another Class
, leave the Cable Switch in
repeater
the “Crossover” position. See Figure 1-4 for a diagram showing the cascade
switch settings. To verify the pin wiring of your UTP cable, refer to
“Appendix B Cabling Guidelines” on page 11.
Using a Straight-Through Cable
Leave the cascade switch
in the default crossover
(MDI-X) position when
connecting the last UTP
port (port 4 or port 8) on
the EtheRx Hub to a
network card or router (or
other MDI-configured
device.)

Notes on MDI and MDI-X Ports
MDI (Media Dependent Interface) is the IEEE 802.3 standard for the interface
to the UTP cable. For two 100BASE-TX devices to communicate with each
other, 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 one
MDI-X port that implements the cross-over internally.

Port 1 through Port 3 (or 7) respectively, like all normal hub ports, are
configured MDI-X, whereas the last UTP ports, Port 4 or Port 8, support both
port configurations, MDI and MDI-X. All NICs (Network Interface Cards) and
Router ports are usually by default configured MDI. A simple illustration

4 or 8 UTP Ports
The UTP ports are numbered 1 through 4 or 1 through 8 for 100BASE-TX
connections. Since crossover function is implemented on all UTP MDI-X
ports, a straight-through UTP cable should be used. (Note: Port 4 and Port 8
support both cable types using the cascade switch. Refer to Appendix A & B
for details on RJ-45 pin assignments and cable guidelines.
DC Power Connector
The EtheRx hub gets its power from the auto-sensing power supply. Insert the
power jack into the DC 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 EtheRx hub and the
power supply. (NOTE: The power supply output voltage is 5VDC/2.0A.
Polarity on the power jack and DC power connector is negative (-) on the
outside and positive (+) on the inside.)

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. For
100BASE-TX networks, Category (CAT) 5 should be used.
With the advent of 100Mbit network products, it is best to use higher quality
CAT 5 cables like Belden or Helix as well as CAT 5-compliant patch panels
and connectors while following the EIA/TIA wiring standards. 100 Ohm
UTP/STP CAT 3, 4 & 5 type cables use 4-pair UTP wiring.
Refer to the illustrations on page 12 for standard 100BASE-TX wiring and 4-
pair 100Mbit wiring using either T568A (Table B-3) or T568B (Table B-4)
wiring standards. Both T568A and T568B wiring configurations are
compatible with 10BASE-T and 100BASE-TX and require no special hardware
configurations. However, it is highly recommended that only one wiring
scheme be used in premise wiring to avoid potential problems.

Rating Codes
UTP cables meet different UL-NEC requirements based 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 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. TWISTED PAIR (UTP) – Two insulated copper wires twisted around
each other to reduce interference from one wire to the other. The twists
are varied in length to reduce the potential for signal interference between
pairs. Several sets of twisted pair wires may be enclosed in a single cable.

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.

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 150 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
17
Category 5 Compliance vs. Category 5 Performance?
Having CAT 5 components in your network installation does not necessarily
achieve full Category performance. To achieve any category-rated
5
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.
