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 Pro-Series® 19-inch
rack-mount, stackable 10BASE-T Ethernet Hub. There are two models: the
KNE16TP/RS and KNE24TP/RS, 16-Port and 24-Port Ethernet hubs,
respectively. The Pro-Series models offer several new enhancements. The
Stack-n-Play® feature allows for easy installation without the need to configure
ID switches. The Hot-Stack® feature allows adding new hubs without powering
down. The Smart Monitor® feature offers network traffic monitoring through a
bar-graph LED display.
The EtheRx hubs provide sixteen (16) or twenty-four (24) UTP (Unshielded
Twisted-Pair) ports for 10BASE-T Ethernet connections, one BNC port for
10BASE2 thin Ethernet connection, and one AUI (Attachment Unit Interface)
port for either 10BASE2 Cheapernet, 10BASE5 thick Ethernet, 10BASE-T,
10BASE-FL, or FOIRL (Fiber Optic Inter Repeater Link) segment using a
proper external transceiver. The last UTP port (i.e., Port 16 or Port 24) uses a
cascade switch to support both crossover and straight-thru cable wiring for
uplinking to another 10BASE-T hub.
The EtheRx models can also be stacked up to five hubs using the stacking
cable (provided) expanding your network to a maximum of 80 or 120 UTP
ports (depending on the model) as a single repeater unit. The EtheRx hubs can
be used on desktop or 19-inch rack-mount installations (mounting hardware
included). The front panel includes pull handles for rack-mounting and a
variety of diagnostic LEDs including: Power, five levels of Utilization and
Collision status, AUI, BNC, and UTP port LEDs which display Link, Activity
and Partition status.

Design Features
The EtheRx Pro-Series hubs comply with the full set of repeater functions as
defined by IEEE802.3 CSMA/CD and IEEE 802.3i 10BASE-T Ethernet
standard. These functions include all Repeater Functions, Signal Regeneration,
Jabber Lockup Protection, Fragment Extension, Collision-Handling, Auto
Partitioning/Reconnection and Link Test. These functions are usually
transparent to all network activities and are summarized below.
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 802.3 specification in
terms of preamble structure, voltage amplitude, and timing characteristics.
These timing regenerations prevent cumulative signal loss, jitter, and distortion
caused by the network cabling, and allow the EtheRx hubs to be cascaded to
other Ethernet hubs.
Jabber Lock-up Protection
The EtheRx hubs implement a built-in jabber protection scheme to ensure that
the network is not disabled due to transmission of excessively long data
packets. This protection scheme will automatically interrupt the reception of
abnormally long streams of data to prevent jabber lock-up.
Fragment Extension
If the total packet length received by the EtheRx hub is less than 96 bits,
including preamble, then the hub will automatically extend the repeated packet
length to 96 bits by appending a jam sequence to the original fragment. The
extension of a fragmented packet allows the reliable detection of a collision by
all stations attached to the network.
Collision-Handling
The EtheRx hubs will perform collision detection and respond to collision
conditions as defined in the IEEE 802.3 specifications.

Design Features
Automatic Partitioning/Reconnection
If any of the ports on the EtheRx hub experience excessive numbers of
consecutive collisions, duration 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
transmitted or received without incurring a collision, the hub will automatically
reconnect that port to the network.
Link Test
For UTP port connections, the EtheRx hub implements the link integrity test
function as specified in the IEEE 802.3i 10BASE-T standard. The hub will
transmit link test pulses to any UTP port after that port’s transmitter is inactive
for a range of 8ms to 17ms. These pulses are sent to confirm that a valid
connection exists between each UTP port on the hub and its attached device.

The green LED indicates the power status. The LED will light when the AC
power cord is connected from a power source to the hub and the power switch
is turned on.
Utilization LEDs
Kingston’s Smart Monitor™ bar-graph LEDs for utilization and collision
provide easy monitoring of network traffic. There are five Utilization LEDs to
display the amount of network traffic in five percentage levels. The amount of
data traffic is measured in frames per second (FPS), then calculated into the
following percentage forms: 1%, 7%, 15%, 30%, and 60%. The LEDs will
light in a bar-graph fashion based on the network activity.
Collision LEDs
There are five Collision LEDs to display the amount of data packet collisions
in five percentage levels. The amount of data collisions is measured in
collisions per second (CPS), then calculated into the following percentage
levels: 1%, 7%, 15%, 30%, and 60%. The LEDs will light in a bar-graph
fashion based on the amount of collisions.

Hardware Installation
AUI LED
The two-color LED displays two states of operation for the Activity and
Partition status on the AUI port. When data is received, the LED will flash
green. If the port has been partitioned due to excessive collision or other faulty
condition, it will display solid red.
Note: Upon power up, the AUI port LED will not be lit unless a transceiver is
attached to the port and there is activity.
BNC LED
The two-color LED displays the Activity and Partition status on the BNC port.
When data is received, the LED will flash green. If the port is partitioned due
to excessive collision or other faulty condition, it will display solid red.
Note: Upon power up, if the BNC port has no cable attached or is not properly
terminated at both ends, the LED will display red to show the port has been
partitioned. Upon receipt of good packets, the LED will automatically change
from red to green indicating that the port is functioning properly.
UTP Port LEDs
The sixteen or twenty-four UTP Port LEDs offer condition status for Link,
Activity, and Partition. If a good link is established on any given port, the
green LED will be continuously lit, indicating a valid network connection
between the network node and the hub. When data is received, the LED will
flash green. If the port is partitioned, the LED will display solid red.
If the LED does not display solid green indicating a good link, check the
following:
1. Make sure the power is turned on for both the PC
and EtheRx Hub. The power LED should be lit.
2. Verify the network drivers have been loaded from the PC. Some
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, 2, 3, and 4 are correct, the cable may be defective or
not wired correctly. Replace the cable and try again. Please
refer to Appendix A for pin assignments and Appendix B for
cabling guidelines.

Cascade Switch
The cascade switch provides cable wiring flexibility on the last UTP Port (i.e.,
Port 16 or Port 24) 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-Thru”), the port is used to connect a workstation.
For cascading to another hub using a straight-thru cable, move the cascade
switch to “Straight-Thru” (right side). If a crossover UTP cable is used to
cascade to another hub, leave the cascade switch in the “Crossover” position.

MDI (Media Dependent Interface) is the standard that defines the mechanical
and electrical configuration of a UTP port. For any two devices to
communicate 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 one MDI-X port that implements the cross-over internally.

Stacking EtheRx Hubs
The EtheRx hubs use stacking ports located on the rear panel to stack up to five
hubs in any combination of 16-Port KNE16TP/RS and 24-Port KNE24TP/RS
models. Follow the directions below to stack up to five hubs together:
1. Locate the 5.5” shielded stacking cable included with your package
contents.
2. Plug one end of the cable into the port labeled, “Stack-Out” on the
first hub.
3. Plug the other end of the cable into the “Stack-In” port on the second
hub.
4. Connect the AC power cord to each hub, then flip the power switch
to turn on power to the unit.
5. Repeat the process to stack additional hubs up to a maximum of five
(5) hubs.
Kingston’s Stack-n-Play™ feature offers greater scalabilty to add UTP ports
without the need to configure ID or termination switches. EtheRx hubs when
stacked together are recognized as a single repeater unit on the network. By
stacking hubs together, you can expand the total number of UTP port
connections from 16 to 80 or from 24 to 120 UTP ports, depending on the
model. A maximum of five (5) Pro-Series hubs can be stacked in any
combination of 16 and 24-Port hub models.
Kingston’s Hot-Stack™ feature allows the addition of new hubs to the top or
bottom of a stack without the need to power down the existing hubs.

Network Configurations
The installation of the EtheRx hub is simple and can be configured for either
the Ethernet Star topology or Linear Bus topology. The hubs may also be
vertically stacked or horizontally cascaded to other Ethernet hubs. For
cascading, please observe the Ethernet 5-4-3 Rule.
Ethernet 5-4-3 Rule
The Ethernet 5-4-3 rule states that the maximum transmission path permitted
between any two stations is:
•
•
•
5 segments
4 repeater sets
3 coax segments. The remaining 2 segments may be linked segments
Ethernet Star Network
The typical network configuration for 10BASE-T Ethernet is a Star Topology,
in which nodes are connected to a central Ethernet hub. Since a Crossover
function is implemented on all ports (except the last UTP port which uses a
cascade switch to support both cable types), a straight-thru UTP cable should
be used. The physical network connection is illustrated in Figure 4.

Linear Bus Network
The typical network configuration for 10BASE2 networks is a Linear Bus
topology in which nodes are connected via thin coaxial cabling using the BNC
connector. A 50Ω (Ohm) terminator must be attached to each end of the trunk
segment and one of the terminators must be grounded. The maximum cable
length is 185M per segment. To minimize cable-related problems, do not mix
single filament (black PVC jacket) with stranded filament (DEC grey) coaxial
cables on the same network.

Horizontal Cascading
The EtheRx hubs can be horizontally cascaded to other hubs as long as the
Ethernet 5-4-3 Rule is met. This connection can be made through the BNC
port, AUI port, or one of the UTP ports. To cascade to another hub, use the
last UTP port which has a cascade switch to support either straight-thru or
crossover cable types. Figure 6 below is an example of horizontal cascading
using the KNE24TP/RS under the Ethernet 5-4-3 rule.

Cascading with Stacked Hubs
By stacking up to five Pro-Series hubs per segment, the number of UTP ports
increases dramatically. The total number of UTP ports changes from 90 (shown
in Figure 6) to 474 (shown below). Figure 7 listed below is an example of
horizontal cascading with stacked hubs under the Ethernet 5-4-3 rule.

Appendix B Cabling Guidelines

Cabling Suggestions
When connecting UTP network cables, the following guidelines are suggested
for trouble-free operation.
• Use CAT 5 Equipment for Future 100Mbps Networks
For true Category 5 compliance, all components including: UTP trunk
cables, UTP patch cables, patch panels and modular wall plugs must be
CAT 5 certified. A CAT 5 cable certifier may be used to ensure CAT 5
compliance.
• Never Exceed a Cable’s Minimum Bend Radius
For Category 5 cables, the cable may not be bent beyond 5 times its own
diameter (i.e., 1.25”).
• Do Not Exceed the Maximum Tensile Loading
The maximum tensile load is the amount of stress a cable can withstand
before performance begins to decline. This level usually occurs far
before the breaking point of the cable. Tensile loading is measured in
pound-foot (lbf). For 24 AWG Category 5 cables, the maximum tensile
loading should not exceed 25 lbf.
• Do Not Over-Cinch the Cables
When grouping a set of cables with cable ties, cords, or staples, over-
cinching can cause the cable jackets to compress causing a deterioration
of cable integrity. Use proper cable clamps or “D” rings which allow for
the cable’s width and girth.
• Do Not Untwist the Pairs on CAT 5 Cables Beyond 0.5”
Care should be taken to never untwist the pairs beyond 0.5 inches from
the point of termination. This rule is in accordance with TIA/EIA-568
guidelines.
• Keep UTP Cables Away From Power Lines
A minimum of five inches should be kept from electrical fixtures, such
as fluorescent lights, transformers, and other high power devices to avoid
possible interference.
• Do Not Run Cables Longer Than The Maximum Length
The maximum cable lengths includes all patch cords from node to wall
plug and patch panel to hubs.

Appendix B Cabling Guidelines
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-4)
or T568B (Fig. B-5) wiring standards. Both T568A and T568B wiring is
compatible with 10BASE-T and 100BASE-TX and require no special
configurations, but stick to one wiring standard. If your building is wired for
T568A, any changes or additions must be done with the T568A wiring scheme.
Mixing the T568A and T568B wiring schemes will not work.
