Introduction

Intended Audience: This manual assumes that the user has a general working knowledge of networking principles and its architecture.

Congratulations on the purchase of your Kingston Fast EtheRx Stackable 100BASE-TX19”Rack-MountableFast Ethernet Hub. There are three models available: KNE8TX/RS, KNE12TX/RS, and KNE24TX/RS,8-Port,12-Port,and24-PortFast Ethernet hubs, respectively. The Fast EtheRx models are100BASE-TXClassI and ClassII compliant repeaters which conform to IEEE 802.3u 100Mb/s CSMA/CD (Carrier Sense Multiple Access with Collision Detection) networks using Category 5 Unshielded Twisted Pair (UTP) cabling. There is also an optional100BASE-FXplug-inmodule available for either SC orST-typeconnectors. The Fast EtheRx100BASE-TXhubs operate at 100Megabits per second (Mbp/s)out-performingstandard10BASE-TEthernet 10Mb/s operation by up to 10 times faster.

The Fast EtheRx hubs offer eight (8), twelve (12), or twenty-four(24) UTP ports for100BASE-TXFast Ethernet connections. The last UTP port offers twoRJ-45connectors to support both crossover orstraight-throughcable wiring for uplinking to one other100BASE-TXClassII repeater. The Fast EtheRx hubs can also be stacked (using any combination of these 3 models) up to six hubs using the stacking cable provided. This allows a maximum of 48, 72, or 144 UTP ports (depending on the model) on a single collision domain. The Fast EtheRx hubs can be used on desktop or19-inchrack-mountinstallations (mounting hardware included). For easytrouble-shooting,the front panel includes a variety of diagnostic LEDs including: Power, Collision, Utilization and UTP port LEDs which display Link, Activity and Partition/Error status.

For the remainder of this manual, the Fast EtheRx Stackable Fast Ethernet Hubs will be referred to collectively as the Fast EtheRx Hubs. For clarity, the three models will be differentiated as follows:

KNE8TX/RS – Fast EtheRx Stackable 8-PortFast Ethernet hub

KNE12TX/RS – Fast EtheRx Stackable 12-PortFast Ethernet hub

KNE24TX/RS – Fast EtheRx Stackable 24-PortFast Ethernet hub

Design Features

The Fast EtheRx 100BASE-TXhubs comply with the full set of repeater functions as defined by IEEE 802.3u, clause 27. These functions include all Repeater Functions, Signal Regeneration, Jabber Lockup Protection, CollisionHandling,Error-Handling,and Auto Partitioning/Reconnection. 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 Fast EtheRx hub will re-transmitthe received data to all other ports on the network. The retransmission of packets complies with the IEEE 802.3u specification in terms of preamble structure, voltage amplitude, and timing characteristics. These timing regeneration’s prevent cumulative signal loss, jitter, and distortion caused by the network cabling, and allow the Fast EtheRx Hubs to be uplinked to another100BASE-TXswitching hub or cascaded to other ClassII Repeater.

Jabber Lock-upProtection

The Fast EtheRx hubs implement a built-injabber 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 jabberlock-up.

Collision-Handling

The Fast EtheRx hubs will perform collision detection and respond to collision conditions as defined in the IEEE 802.3u specifications.

Error-Handling

With 100BASE-TXFast Ethernet, the newerror-handlingfeature prevents substandard links from generating streams of false carrier and interfering with other links.
