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) series100BASE-TXFast Ethernet hubs. There are two models available in this series: KNE4TX/WG, which is the4-Portmodel, and KNE8TX/WG, which is the8-Portmodel. The EtheRx Workgroup series hubs are ClassII repeaters that conform to IEEE 802.3u100BASE-TXstandards. Please refer to Appendix D for further information on ClassII repeaters.

The EtheRx Workgroup hubs support up to four (4) or eight (8) UTP (Unshielded Twisted-Pair)ports for100BASE-TXnetwork connections. Both models include a cascade switch on the last UTP port (Port 4 or Port 8) which supports bothstraight-throughand crossover cable types. The UTP ports usedual-colorLEDs to showthree 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-portmodel) and the KNE8TX/WG(8-portmodel) 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,ErrorHandling, 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-transmitthe received data to all other ports on the network. There-transmissionof 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 cascaded to other100BASE-TXClassII 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-bittimes.

Collision-Handling

The EtheRx hub will detect and respond to collision conditions as outlined in the IEEE 802.3u specifications.

Error-Handling

The 100BASE-TXstandard uses an improved method oferror-handlingcalledblock coding. With100BASE-TXFast Ethernet, the newerror-handlingfeature 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.
