  • Page 22: Power Supply Receptacles

    IGER WITCH Optional Redundant Power Unit SMC’s Redundant Power Units (RPUs) are separate devices and each has its own power cord. These devices can supply power to the unit in the event of a failure of the internal power supply.

  • Page 23: Switch Architecture

    WITCH Switch Architecture Switching Methods Adaptive Cut-Through SMC’s TigerSwitch 100 models employ a dynamic forwarding architecture that enables them to support adaptive cut-through frame forwarding mode. This approach allows the switch to automatically alternate between three different switching methods to provide the best possible performance in response to current network conditions.

  • Page 24: Spanning Tree Protocol

    BOUT THE IGER WITCH Spanning Tree Protocol The TigerSwitch 100 switches support the ANSI/IEEE 802.1d Spanning Tree Protocol. This protocol adds a level of fault tolerance by allowing two or more redundant connections to be created between a pair of LAN segments. When there are multiple physical paths between segments, the protocol will choose a single path and disable all others to ensure that only one route exists between any two stations on the network.

  • Page 25: Management Options

    Another method by which these switches may be managed is in-band from a workstation via an SNMP-based manager (i.e., SMC’s EliteView). Simple Network Management Protocol (SNMP) is the most popular management protocol in use today. It defines the structure of information maintained on a device being managed and the operations used to access that information.

  • Page 29: Introduction To Switching

    PLANNING Introduction to Switching An Ethernet or Fast Ethernet switch allows simultaneous transmission of multiple packets via high-bandwidth shared memory. This means that it can partition a network more efficiently than bridges or routers. The switch is, therefore, fast being recognized as one of the most important building blocks for today’s networking technology.

  • Page 30: Sample Applications

    PLANNING Sample Applications The TigerSwitch 100 is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications for the TigerSwitch 100 are described below. Collapsed Backbone The TigerSwitch 100 is an excellent choice for Ethernet installa- tions where significant growth is expected in the near future.

  • Page 31: Multiport Bridging

    In the figure below, the 10BASE-T/100BASE-TX ports on the TigerSwitch 100T (Model SMC6608T) are providing 100 Mbps connectivity for up to 16 segments through SMC’s TigerStack™ 100 hubs. In addition, the switch is also connecting servers at 200 Mbps.
  • Page 32 PLANNING Server Farm Aggregation The advantages of mixed-media can also be easily exploited with the TigerSwitch 100M because of the various port configu- rations available among its 4-port modules. In the following example, a TigerSwitch 100M, equipped with modules featuring 10BASE-T/100BASE-TX and 100BASE-FX ports, is providing localized Fast Ethernet connectivity between an expanding server farm and associated LANs.

  • Page 33: High-Speed Switch Links

    In the following figure, the TigerSwitch 100M (Model SMC6608M) is cascaded via the 10BASE-T/100BASE-TX daisy- chain port to an 8-port Fast Ethernet switch, SMC’s EZ Switch™ 100, forming a high-speed 200 Mbps, full-duplex backbone. The other 10BASE-T/100BASE-TX ports are connected to power users, and the 100BASE-FX ports are connected to servers.

  • Page 34: Collapsed Backbone

    PLANNING Collapsed Backbone with Fiber Cable Fiber optic technology allows for a longer cable run distance (up to 2 km in full-duplex) than any other media type. The TigerSwitch 100M, used as a collapsed backbone to interconnect multiple Fast Ethernet segments with fiber cable, is a convenient way to provide direct connectivity for a wide-spread LAN.

  • Page 35: High-Speed Fiber Backbone

    PLANNING High-Speed Fiber Backbone When maximum network reach is required, the TigerSwitch 100M (Model SMC6608M) can be used to help create a high- speed fiber backbone. In the figure below, a TigerSwitch 100M employed as a collapsed backbone is also part of a full-duplex, 200 Mbps fiber backbone.

  • Page 36: Application Notes

    PLANNING Application Notes 1. Full-duplex operation only applies to point-to-point access (e.g., when the switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. 2. For network applications that actually require routers (e.g., interconnecting dissimilar network types), attaching switches directly to a router can significantly improve overall network performance.

For 10BASE-T connections, two pairs of 100 Ohm Category 3, 4 or 5 cable are required. 100BASE-TX connections require two pairs of certified Category 5 cable. Every twisted-pair connection must have a wiring crossover to transmit and receive data.

    SNMP ANAGEMENT VIA SNMP Protocol SNMP (Simple Network Management Protocol) is a communica- tion protocol designed specifically for the purpose of managing devices or other elements on a network. Network equipment commonly managed with SNMP includes hubs, switches, bridges, routers and host computers. SNMP is typically used to configure these devices for proper operation in a network environment, as well as monitor them to evaluate performance and detect potential problems.

    SSIGNMENTS RJ-45 Pin Assignments Caution: Regulations regarding the connection of equipment to telephone networks vary from country to country. Check with your local telephone network supplier before using existing telephone wiring. An Ethernet twisted-pair link segment requires two pairs of wires—Category 3, 4 or 5 for 10 Mbps connections and Category 5 for 100 Mbps connections.
