Introduction 1 Introduction Intended Audience: This manual assumes that the user has a general working knowledge of networking principles and is familiar with network systems in general. Congratulations on the purchase of your Kingston Fast EtheRx Stackable 10/100TX Rack-Mountable Dual Speed hub. The KND2415TX is a full 19” rack-mount unit. The Fast EtheRx Stackable 10/100TX Dual-Speed hub conforms to IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T, and IEEE802.3 CSMA/CD standards.
2 Special Features Special Features • • • • • • • • • • • • • Conforms to IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T, and IEEE802.
Design Features 3 Design Features The Fast EtheRx dual-speed hub complies with the full set of repeater basic functions as dened by IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T, and IEEE802.3 CSMA/CD standards. Repeater Functions If any single port senses the start of a valid packet on its receiving line, the dual-speed hub will re-transmit the received data to all other ports on the network. The re-transmission of packets complies with the IEEE 802.
4 Hardware Installation Hardware Installation Before you begin installing network cables, please take a few minutes to familiarize yourself with the dual-speed hub. See the diagram below: Front Panel Fig. 3-1 Front Panel Power LED The green LED indicates the power status. The LED will light up when the AC power connector is properly connected to a power source. Collision LEDs There are two (2) separate collision LEDs for both 10Mbps and 100Mbps segments.
Hardware Installation 5 4. Make sure the cable is wired properly and connected on both ends. 5. If steps 1 through 4 are correct, the cable may be defective or not wired correctly. Please refer to Appendix A for pin assignments and Appendix B for cabling guidelines. 10/100TX UTP Ports The twenty-four (24) 10/100TX UTP ports auto-negotiate both 10BASE-T and 100BASE-TX connections. . All ports like all normal hub ports are congured as MDI-X.
6 Hardware Installation Power Switch The AC Power switch turns the unit ON or OFF. If the PWR LED does not light up once the unit has been turned on, try the procedures below (in the following order): 1. Try a different AC power outlet. 2. Check the external fuse located at the back of unit (below the AC power connector). If the fuse is blown, replace it with the spare fuse provided with the unit. (See Fuse Compartment display in Figure 3-3) 3. The power supply may be defective.
Hardware Installation 7 Stack-In / Stack-Out Ports Fig. 3-4 Stacking Conguration The Fast EtheRx stackable hub uses stacking ports located on the back of the unit to stack up to a maximum of four hubs. IMPORTANT: The KND2415TX can only be stacked with other KND2415TX units. Stacking the unit with any other model hub may cause damage to the units. Follow the directions below on stacking these hubs together: 1. Power down the Fast EtheRx hub(s). 2.

Appendices 9 Appendices KND2415TX Users Guide - Rev.
10 Appendix A Pin Assignments Appendix A Pin Assignments UTP Port Pin Assignments UTP Ports use RJ-45 Unshielded Twisted Pair (UTP) cabling. RJ-45 modular plugs and their pin numbers and wiring assignments are listed below. TwistedPair 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. Fig.
Appendix B Cabling Guidelines 11 Appendix B Cabling Guidelines UTP Cable Type When installing network cables, the following table shows appropriate cabling guidelines for 100BASE-TX Fast Ethernet architecture. Table B-1 Network Cable Guidelines (NOTE: All UTP cables come in both solid and stranded lament. Solid lament cables are more rigid and usually intended for trunk cabling. Stranded lament cables are more pliable and generally targeted for patch cables.
12 Appendix B Cabling Guidelines UTP 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.
Appendix B Cabling Guidelines 13 UTP Cable Rating Codes UTP cables meet different UL-NEC requirements based 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 D Commonly Asked Questions Appendix D Class 15 Commonly Asked Questions vs. Class 100BASE-TX Fast Ethernet Repeaters There are currently two classes of Fast Ethernet repeaters, dened as Class Class . and Class : in a maximum length segment topology, only one Class repeater may exist between any two nodes within a single collision domain. Class : in a maximum length segment topology, two Class repeaters may exist between any two nodes within a single collision domain.
16 Appendix D Commonly Asked Questions What are the Guidelines for Proper Termination? It is important to maintain the twists of the cable as close to the termination on the outlet as possible, to avoid NEXT (Near End Cross Talk) and to maintain the transmissions characteristics of the Category.
Appendix E Mounting Templates Appendix E 17 Mounting Templates The Fast EtheRx dual-speed hubs can be stationed on a at surface using the four rubber feet provided, or mounted in a standard 19” rack by using the mounting brackets and 4 thumb screws provided with the unit. Rubber Feet for Desktops The Fast EtheRx dual-speed hubs come with rubber feet that may be applied to the bottom of the unit for desktop surface installations. The 4 rubber feet have peeloff adhesive backing.
