  • Page 25: Appendix A Fast Ethernet Topology Rules

    Fast Ethernet Topology Rules This appendix describes • • For a complete explanation of the set of 100BASE-T rules and guidelines, refer to the Institute of Electrical and Electronics Engineers (IEEE) 100BASE-T 802.3u standard. For information about cables for Ethernet networks, refer to the Electronic Industries Association/Telecommunications Industry Association (EIA/TIA) wiring standard EIA/TIA 568.

  • Page 26: Basic Rules

    • You can’t use UTP cabling to connect Express Stackable Hubs to each other. Express Stackable Hubs are Class I repeaters and can be connected only with Intel Cascade Cables. Distance limitations 100BASE-T4 and 100BASE-TX The EIA/TIA 568 wiring standard specifies that UTP wiring must not exceed 100 meters (328 feet) from repeater to workstation or switch.
  • Page 27 A P P E N D I X Fast Ethernet Topology Rules Repeater rules The 100BASE-T standard defines two types of repeaters — Class I and Class II. The Express Stackable Hub is a Class I repeater. Class I repeaters (sometimes called translational repeaters) limit the number of repeaters in a physical domain to one.

  • Page 28: Network Topology Extensions

    A P P E N D I X Intel Express 100BASE-T4 Stackable Hub Network Topology Extensions You can extend the network topology by connecting Express Stackable Hubs to a switching hub. In the illustration below, the network topology is extended to a maximum of 400 meters (1312 feet).
  • Page 29 491 meters (1610 feet). In this network, a 160 meter (524 feet) fiber link connects the 100BASE-TX repeater to the switch, and a 131 meter (429 feet) fiber link connects the 100BASE- T4 repeater to the switch. 100 meter (328 feet) Category 5 UTP wiring connects workstations and servers to the repeater stacks.
  • Page 30 A P P E N D I X Intel Express 100BASE-T4 Stackable Hub You can extend the 100BASE-T network topology further by interconnecting the switches using fiber links. Interconnecting two switches creates a network that contains four separate collision domains. The overall network topology grows while each collision domain can be modeled after the extended collision domains shown in the previous two illustrations.
  • Page 31 100 Mbps equipment in your network. The Intel 100BASE-TX Uplink Module (Intel product code EC100MATX) provides a standard RJ-45 connector for Category 5 UTP cable. The maximum distance between the port and the attached 100BASE-TX device is 100 meters (including all patch cables, panels, and connectors).
