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 Kingston EtheRx WorkGroup (WG)
series and Stackable-Enhanced (SE) series 10BASE-T Ethernet hubs. There are
two models for each series: KNE8TP/WG and KNE16TP/WG, 8 and 16-Port
WorkGroup hubs, and KNE8TP/SE and KNE16TP/SE, 8 and 16-Port
Stackable hubs. The SE hubs have the same list of features as the WorkGroup
hubs, but also include stacking ports located on the front panel to stack up to
five (5) SE hubs in the same network segment. The EtheRx WG and SE hubs
are multi-port repeaters that conform to IEEE 802.3 10Mbit/sec CSMA/CD
(Carrier Sense Multiple Access with Collision Detection) Network.

The EtheRx WG and SE hubs support eight (8) or sixteen (16) UTP
(Unshielded Twisted-Pair) ports for 10BASE-T network connections, and one
BNC port for 10BASE2 thin Ethernet connection. The 16-Port models also
include one AUI (Attachment Unit Interface) port for either 10BASE2
Cheapernet, 10BASE5 thick Ethernet connection, 10BASE-T or FOIRL (Fiber
Optic Inter Repeater Link) segment using a proper external transceiver. All
models include: a cascade switch on the last UTP port (Port 8 or Port 16)
which supports both straight-through or crossover cable types by simply
moving the switch on the front panel. The UTP ports use 2-color LEDs to show
three states of operation: link, activity and partition. The AUI and BNC ports
use 2-color LEDs to show two states of operation: activity and partition. The
EtheRx hubs also include utilization and collision LEDs to visually monitor the
level of network traffic and number of collisions in five LED percentage levels.

For the remainder of this manual, these hubs will be referred to collectively as
the EtheRx hubs. When necessary for clarification, the four models will be
differentiated as follows:

• KNE8TP/WG 8-Port WorkGroup hub

• KNE16TP/WG 16-Port WorkGroup hub

• KNE8TP/SE 8-Port Stackable hub

• KNE16TP/SE 16-Port Stackable hub

4 Design Features

Design Features

The EtheRx hub complies with the full set of repeater basic functions as
defined by IEEE 802.3, Section 9. 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 hub implements a built-in MAU jabber lockup protection (MJLP)
scheme to ensure that the network is not disabled due to transmission of
excessively long data packets. This protection scheme will automatically
interrupt excessively long transmissions 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 hub will detect and respond to collision conditions as outlined in
the IEEE 802.3 specifications.
