ABOUT THE TIGERSWITCH 100 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 ports with built-in crossovers. Figure 1-4.
PAGE 20
ABOUT THE TIGERSWITCH 100 Status LEDs The LEDs on the TigerSwitch 100 models are located on the front panel for easy viewing. For a more complete discussion of the front-panel LEDs, see Chapter 4, “Configuration and Management.” Figure 1-6. Front Panel LEDs Figure 1-7.
PAGE 21
ABOUT THE TIGERSWITCH 100 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.
PAGE 22
ABOUT THE TIGERSWITCH 100 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 application.
PAGE 23
ABOUT THE TIGERSWITCH 100 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
ABOUT THE TIGERSWITCH 100 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. This prevents the creation of network loops.
PAGE 25
ABOUT THE TIGERSWITCH 100 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 Telnet ♦ 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 console port with an RS-232 full-handshaking null modem cable.

PAGE 29
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
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 installations where significant growth is expected in the near future. You can easily build on this basic configuration, adding direct full-duplex connections to workstations or servers.
PAGE 31
PLANNING 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 connectivity for up to 16 segments through SMC’s TigerStack™ 100 hubs. In addition, the switch is also connecting servers at 200 Mbps. Figure 2-2.
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 configurations 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. Figure 2-3.
PAGE 33
PLANNING 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 communicate with any other node in the network.
PAGE 34
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. The figure below illustrates a TigerSwitch 100M connecting multiple segments with up to 2 km of fiber cable. Figure 2-5.
PAGE 35
PLANNING High-Speed Fiber Backbone When maximum network reach is required, the TigerSwitch 100M (Model SMC6608M) can be used to help create a highspeed 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.
PAGE 36
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.

INSTALLATION Mounting and Stacking the Switch on a Flat Surface 1. Attach the four adhesive feet to the hollow spaces on the bottom of the switch. Figure 3-3. Attaching the Adhesive Feet 2. Set the switch on a flat surface near an AC power source, making sure there are at least 4 inches (10 cm) of space in the front and back for proper air flow. 3. To stack switches, repeat Step 1 for every subsequent switch and then gently place each new switch on top of the previous switch.
PAGE 44
INSTALLATION Powering Up Connecting to a Power Source 1. Power on the switch by plugging one end of the power cord into the power socket on the rear panel, and the other end into a power outlet. (See Chapter 2 for a description of the rear-panel power receptacles) North America: Each switch is shipped with one standard AC line cord for North America (UL and CSA approved). International: The international version of each switch is shipped with AC line cords for Continental Europe and the UK.
PAGE 45
INSTALLATION 3. Check to insure that the front-panel Power LED is lit. If not, check that the power cable is correctly plugged in. (Refer to Chapters 1 and 4 for detailed explanations of the LEDs.) Diagnostics Upon power up, the system performs an internal self-diagnostic test of major switch components. If any component fails during the test, the switch will try to complete the diagnostic procedure. Otherwise, the system will hang.
PAGE 46
INSTALLATION 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 Ethernet collision domains is provided below.

MANAGEMENT VIA SNMP SNMP Protocol SNMP (Simple Network Management Protocol) is a communication 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.
PAGE 84
MANAGEMENT VIA SNMP the manager software, and result in a response by the agent. The third operation type, the TRAP, allows the agent to send an unsolicited message to the manager. This operation is typically used as an alert to a potential problem, or a change in device status. MIB Objects A number of different MIB specifications have been defined for managing network equipment; some are standard, others are proprietary.
PAGE 85
MANAGEMENT VIA SNMP SNMP Parameter Configuration In order to access the SNMP agent resident in the TigerSwitch 100 units, the switch must be configured with a valid IP address, default gateway and subnet mask. This is accomplished through the System Configuration Program, which can be accessed in-band or out-of-band (See Chapter 4, “Configuration and Management”). Additional SNMP operating parameters may also be configured through this program. Assigning SNMP Agent Access Rights 1.

TROUBLESHOOTING Switch Indicators The LED indicators on TigerSwitch 100 can be of assistance in identifying problems. Some common problems and possible solutions are described below. Symptom: Link LED does not light up (green) after making a connection. Cause: Network interface (e.g., network card on the attached device), network cable or switch port may be defective, 4-port module (Model SMC6608M) is not properly seated. Solution: Verify that the switch and attached device are powered on.
PAGE 90
TROUBLESHOOTING Diagnostic Tests Upon power-up, the TigerSwitch 100 units perform selfdiagnostic tests (See Chapter 3). Diagnostic tests similar to those performed on power-up can be run using the Configure button: 1. Use a long press (>2 seconds) to begin function selection. The Status LED will start to flash to indicate that functions may be selected. Use short presses (<2 seconds) to cycle through the status LEDs until the Diagnostic LED lights. Use a long press to initiate diagnostic tests.

TROUBLESHOOTING Port Diagnostic Tests Port Diagnostic Tests, the second diagnostic test phase, check each port.
PAGE 92
TROUBLESHOOTING Communication Mode The communication mode of each port (half or full duplex and 10 Mbps or 100 Mbps) must be identical to the mode of the attached device. Verify that each port is set to the same communication modes used by the attached device. Each 100BASE-FX port must be configured for half- or full-duplex operation. For each 10BASE-T/100BASE-TX port, the communication mode is configured automatically via AutoNegotiation.

TROUBLESHOOTING down by implementing the new changes, one step at a time. Ensure that cable distances and other physical aspects of the installation comply with recommendations. (See “Making Network Connections” in Chapter 3.) Management Interface Terminal Emulation If the terminal attached to the console port is not operating properly, check that: 1. the attached terminal or terminal emulator is set to VT100 2.
PAGE 94
TROUBLESHOOTING System Integrity As a last resort, verify the integrity of the switch with a poweron reset (See Chapter 4, “Configuration and Management”). If the problem still persists and you have completed all the preceding diagnoses, contact SMC Technical Support for further assistance. Be sure to check the Login Screen (Figure 4-1.) for the version of the System Configuration Program (Chapter 4) installed on your TigerSwitch 100.
