2 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-TX 19” Rack-Mountable Fast Ethernet Hub. There are three models available: KNE8TX/RS, KNE12TX/RS, and KNE24TX/RS, 8-Port, 12-Port, and 24-Port Fast Ethernet hubs, respectively. The Fast EtheRx models are 100BASE-TX Class I and Class II compliant repeaters which conform to IEEE 802.
Introduction 3 The Fast EtheRx hubs support optional Fiber Optic plug-in modules which can be ordered for future upgrading by the following part numbers: Accessories Part No.
4 Introduction Special Features • • • • • • • • • • • • 100BASE-TX Class I or Class II compliant repeater Stack up to six Fast EtheRx hubs to create a single repeater unit 8, 12, or 24 UTP ports for 100BASE-TX connection 8, 12, or 24 Link, Activity, and Partition/Error Status LEDs for easy troubleshooting Optional 100BASE-FX modules available (SC or ST connectors) Utilization LEDs display network traffic in five LED percentage levels Power LED and Collision LED for collision detection Automatic partition
Design Features 5 Design Features The Fast EtheRx 100BASE-TX hubs 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.
6 Hardware Installation Automatic Partitioning / Reconnection If any of the ports on the Fast EtheRx Hub experience excessive numbers of consecutive collisions, duration 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 transmitted without incurring a collision, the hub will automatically reconnect that port to the network.
Hardware Installation 7 UTP Port LEDs The UTP Port LEDs indicate Link, Activity, Error, and Partition status. If a good link is established on any given port, the green LED will be continuously lit, indicating a valid network connection between the network node and the hub. When data is received, the LED will flash green. If the port is partitioned or encounters an error, such as jabber, false carrier, misalignment, or invalid packet, the LED will flash amber.

Hub Rear Panels with Stacking Cables Power Switch The power switch toggles power on and off to the unit.
10 Hardware Installation • KNE100TX/RSC for SC connectors. Stacking Fast EtheRx Hubs The Fast EtheRx hubs use stacking ports located on the rear panel to stack up to six hubs in any combination of 8-Port, 12-Port, or 24-Port models. Follow the directions below to stack up to six hubs together: 1. Locate the 50-pin shielded stacking cable included with your package contents. 2. Plug one end of the cable into the port labeled, “Out” on the first hub. 3.
Hardware Installation 11 Installing the 100FX Module (Optional) Kingston offers two optional plug-in modules to support 100BASE-FX Fiber Optic cabling with either SC (Subscriber Connector) or ST (Straight Tip) connector types. Model KNE100FX/RSC supports SC-type connectors. Model KNE100FX/RST supports ST-type connectors. To upgrade your Fast EtheRx Stackable Fast Ethernet hub with either of the 100BASE-FX plug-in modules, follow the directions below. The procedure requires a Philips head screwdriver. 1.

Appendix A Pin Assignments Appendix A 13 Pin Assignments UTP Port Pin Assignments The UTP ports use RJ-45 Unshielded Twisted Pair (UTP) cabling. Connector pin numbers and pin wiring assignments are listed below in Figure A-1. Twisted-Pair cables can be wired with either straight-through or crossover pin assignments. Both wiring schemes are mentioned in "Appendix B Cabling Guidelines" for reference in creating a twisted-pair cable.
14 Appendix B Appendix B Cabling Guidelines Cabling Guidelines Cable Type When connecting network cables, the following table shows appropriate cabling guidelines for 100BASE-TX Fast Ethernet architecture. Ethernet Standard: Trunk and Patch Cable Type: Max. Cable Length: Hub to Workstation Hub to Hub 100BASE-TX 4-Pair 100Ω UTP CAT 5 (only 2 pairs used) 100M (328ft) 5M (16.4ft) Modular Plug: 8-Pin RJ-45 CAT 5 only Patch Panel: 8-Pin RJ-45 CAT 5 only Network Topology: Star Table B-1.
Appendix B Cabling Guidelines 15 Cable Wiring Standards There are two governmental agencies: the Electronic Industry Association (EIA) and the Telecommunications Industry Association (TIA), which set the standard for all cable wiring requirements for commercial buildings. With the advent of 100Mb/s networking products, it is best to use higher quality CAT 5 cables like Belden or Helix as well as CAT 5-compliant patch panels, patch cables, and connectors while following the EIA/TIA wiring standards.
16 Appendix B Cabling Guidelines UTP Cable Rating Codes UTP cables meet different UL-NEC requirements based mostly on cable-jacket quality. Below is an explanation of the rating codes for each cable type. UL – The National Electrical Code (NEC), published by the National Fire Protection Association (NFPA), details advisory safety considerations for electrical wiring. NEC Article 800 Communications Cables are manufactured to meet these different cable types. 1.
Appendix B 4. Cabling Guidelines 17 NEAR-END CROSSTALK (NEXT) – In wires packed together within a cable, the signals generated at one end of the link can flush out the weaker signals coming back from the receiving end of the link. KNE24TX/RS User’s Guide - Rev.

Appendix D Commonly Asked Questions 21 Appendix D Commonly Asked Questions Class I vs. Class II 100BASE-TX Fast Ethernet Repeaters There are currently two classes of Fast Ethernet repeaters, defined as Class I and Class II . Class I : in a maximum length segment topology, only one Class I repeater may exist between any two nodes within a single collision domain. Class II : in a maximum length segment topology, two Class II repeaters may exist between any two nodes within a single collision domain.
22 Appendix D Commonly Asked Questions Category 5 Compliance vs. Category 5 Performance? Having CAT 5 components in your network installation does not necessarily achieve full Category 5 performance. To achieve any category-rated performance, make sure all cabling components are at least of the minimum category required. To achieve full CAT 5 performance, all components must be CAT 5 compliant and terminated properly according to EIA/TIA-568 TSB-36 and TSB-40 guidelines.
Appendix F Warranties and Notices Appendix E 23 Mounting Templates The Fast EtheRx hubs can be stationed on a flat surface using the four rubber feet provided, or mounted to a standard 19-inch rack by using the mounting brackets on each side of the unit. Rubber Feet for Desktops The Fast EtheRx hubs may use rubber feet applied to the bottom of the unit for desktop surfaces or stacking hubs on top of one another. The four (4) rubber feet have peel-off adhesive backing.
