Optional Redundant Power Unit SMC’s Redundant Power Units (RPUs) are separate devices andeach has its own power cord. These devices can supply powerto the unit in the event of a failure of the internal power supply.The available RPUs are listed in the table below. Contact yourreseller for advice reg...

Switch Architecture Switching Methods Adaptive Cut-Through SMC’s TigerSwitch 100 models employ a dynamic forwardingarchitecture that enables them to support adaptive cut-throughframe forwarding mode. This approach allows the switch toautomatically alternate between three different switching methods ...

Spanning Tree Protocol The TigerSwitch 100 switches support the ANSI/IEEE 802.1dSpanning Tree Protocol. This protocol adds a level of fault tolerance by allowing two or more redundant connections to becreated between a pair of LAN segments. When there are multiple physical paths between segments, th...

Management Options The TigerSwitch 100 units may be managed using any one ofthe following three methods: ♦ Out-of-band via the RS-232 console port ♦ In-band via Telnet ♦ In-band via any SNMP-based network management programthat includes a compiler Serial Console Port The switches may be managed out-...

Key Features and Benefits Connectivity • Slide-in, replaceable 4-port modules for added flexibility (Model SMC6608M only) • 100BASE-FX ports with SC or ST connectors (Model SMC6608M only) • Auto-Negotiation on 10BASE-T/100BASE-TX ports automatically selects optimum communication mode (half orfull du...

Introduction to Switching An Ethernet or Fast Ethernet switch allows simultaneous transmission of multiple packets via high-bandwidth sharedmemory. This means that it can partition a network more efficiently than bridges or routers. The switch is, therefore, fastbeing recognized as one of the most i...

Sample Applications The TigerSwitch 100 is not only designed to segment your network, but also to provide a wide range of options in settingup network connections. Some typical applications for theTigerSwitch 100 are described below. Collapsed Backbone The TigerSwitch 100 is an excellent choice for ...

Multiport Bridging With 8 parallel bridging ports (i.e., 8 distinct collision domains),the TigerSwitch 100 can collapse a complex network down intoa single efficient bridged node, increasing overall bandwidthand throughput. In the figure below, the 10BASE-T/100BASE-TX ports on theTigerSwitch 100T (M...

Server Farm Aggregation The advantages of mixed-media can also be easily exploitedwith the TigerSwitch 100M because of the various port configu-rations available among its 4-port modules. In the following example, a TigerSwitch 100M, equipped withmodules featuring 10BASE-T/100BASE-TX and 100BASE-FXp...

High-Speed Switch Links Most common LAN implementations use a combination of hubs, bridges and routers. The bridges and routers quicklybecome bottlenecks, reducing overall network throughput.Using switches instead of bridges and routers allows you to tietogether LAN segments and retain a cohesive LA...

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. TheTigerSwitch 100M, used as a collapsed backbone to interconnectmultiple Fast Ethernet segments with fiber cable, is a convenientway t...

PLANNING 2-8 High-Speed Fiber Backbone When maximum network reach is required, the TigerSwitch100M (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....

Application Notes 1. Full-duplex operation only applies to point-to-point access (e.g., when the switch is attached to a workstation, server oranother switch). When the switch is connected to a hub,both devices must operate in half-duplex mode. 2. For network applications that actually require route...
