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 andStackable-Enhanced (SE) series10BASE-TEthernet hubs. There are two models for each series: KNE8TP/WG and KNE16TP/WG, 8 and16-PortWorkGroup hubs, and KNE8TP/SE and KNE16TP/SE, 8 and16-PortStackable 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 aremulti-portrepeaters 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 for10BASE-Tnetwork connections, and one BNC port for 10BASE2 thin Ethernet connection. The16-Portmodels also include one AUI (Attachment Unit Interface) port for either 10BASE2 Cheapernet, 10BASE5 thick Ethernet connection,10BASE-Tor 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 bothstraight-throughor crossover cable types by simply moving the switch on the front panel. The UTP ports use2-colorLEDs to showthree states of operation: link, activity and partition. The AUI and BNC ports use2-colorLEDs to showtwo 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:

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-transmitthe received data to all other ports on the network. There-transmissionof 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-upProtection

The EtheRx hub implements a built-inMAU 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 jabberlock-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.
