General Information 1
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
ID switches. The Hot-Stack
down. The Smart Monitor
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 3
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.
