T igerSwitch 100 Overview SMC’s TigerSwitch™ 100 units are intelligent Fast Ethernet switches. There are two TigerSwitch 100 models available. The first, the TigerSwitch 100T (SMC6608T) , features 8 fixed 10BASE-T/100BASE-TX ports. The predominance of dual- speed, Auto-Negotiating ports on the SMC6608T make this unit ideally suited for Fast Eth[...]

Switch Ports 10BASE-T/100BASE-TX Ports These ports are dual-speed RJ-45 ports with built-in wiring crossovers. Each TigerSwitch 100 equipped with 10BASE-T/ 100BASE-TX ports will contain at least one straight-through (daisy-chain) port. This port is used for straight-through cable connections to other devices (i.e., hubs or switches) which have port[...]

Status LEDs The LEDs on the TigerSwitch 100 models are located on the front panel for easy viewing.

Console Port Both TigerSwitch 100 units contain a Console port on the front panel. This is an RS-232 serial port with a DB-9 connector . A PC may be connected to this port for configuration and monitoring purposes out-of band via a full-handshaking null modem cable. (See Appendix B) Figure 1-8. Console Port Configure Button The Configure button is [...]

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. The available RPUs are listed in the table below. Contact your reseller for advice regarding the appropriate RPU for your specific[...]

Switch Ar chitecture 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 [...]

Spanning T ree Protocol The TigerSwitch 100 switches support the ANSI/IEEE 802.1d Spanning T ree 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 disab[...]

Management Options The TigerSwitch 100 units may be managed using any one of the following three methods: ♦ Out-of-band via the RS-232 console port ♦ In-band via T elnet ♦ In-band via any SNMP-based network management program that includes a compiler Serial Console Port The switches may be managed out-of-band using a PC connected to the conso[...]

Introduction to Switching An Ethernet or Fast Ether net 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 networki[...]

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 growt[...]

Multiport Bridging With 8 parallel bridging ports (i.e., 8 distinct collision domains), the TigerSwitch 100 can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10BASE-T/100BASE-TX ports on the TigerSwitch 100T (Model SMC6608T) are providing 100 Mbps connecti[...]

Server Far m 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 co[...]

High-Speed Switch Links Most common LAN implementations use a combination of hubs, bridges and routers. The bridges and routers quickly become bottlenecks, reducing overall network throughput. Using switches instead of bridges and routers allows you to tie together LAN segments and retain a cohesive LAN structure in which any node can freely commun[...]

2-7 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-sprea[...]

PLANNING 2-8 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. Figure 2-6. High-Speed Fiber Backbone[...]

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 typ[...]

If any component fails during the tes[...]

Making Network Connections Switches are designed to interconnect multiple segments, or collision domains. Each segment may contain a single server or workstation, or multiple workstations that are connected to a hub. Connectivity Rules An overview of the rules for both Ethernet and Fast Ether net collision domains is provided below. 10 Mbps Etherne[...]

T wisted-Pair Cabling Guidelines Each 10BASE-T or 100BASE-TX connection requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. 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 h[...]

Connecting 10BASE-T/100BASE-TX Ports Fixed Crossover Ports Insert the RJ-45 connector on one end of a twisted-pair cable into an unused 10BASE-T/100BASE-TX port on the TigerSwitch 100, and the RJ-45 connector on the other end into a port on the other device. 1. Always use straight-through cable when connecting a server or workstation to the switch.[...]

Connecting 100BASE-FX Ports TigerSwitch 100M fiber modules are equipped with either SC or ST connectors. Connect one end of a fiber optic cable to the appropriate fiber connector on the front panel of the TigerSwitch 100M, and the other end to the connector on the other device. 1.

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 fo[...]

Straight-Through Wiring If the twisted-pair link segment is to join two ports and only one of the ports has an internal crossover , the two pairs of wires must be straight-through. Crossover Wiring If the twisted-pair link segment is to join two ports and either both ports are labeled with an “x” or neither port is labeled with an “x,” a cr[...]

Console Port Pin Assignments The DB-9 serial console port on the front-panel is used to connect the switch to a console device, either directly or remotely. The pin assignments for connection to another DB-9 port or a DB-25 port are provided below and on the following pages. Note: Any cable connected to the Console port must be shielded to comply w[...]
