CHAPTER 1 ABOUT THE TIGERSWITCH 10/100 Overview SMC’s TigerSwitch™ 10/100 is a fast Ethernet switch with 24 10BASE-T/100BASE-TX ports, plus two slots for optional slide-in 1000BASE-SX modules. There is also an SNMP-based management agent embedded on the main board. This agent supports both in-band and out-of-band access for managing the switch. Figure 1-1. SMC6724L2 Front Panel Figure 1-2. SMC6724L2 Rear Panel Figure 1-3.
ABOUT THE TIGERSWITCH 10/100 Switch Architecture The TigerSwitch employs a high-speed switching fabric. This design allows for simultaneous transport of multiple packets at low latency on all ports. It also uses store-and-forward switching to ensure maximum data integrity. In this mode, the entire packet must be received into a port buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.
ABOUT THE TIGERSWITCH 10/100 Description of Hardware 10BASE-T/100BASE-TX Ports (SMC6724L2) These ports are dual-speed RJ-45 ports. Ports 1 through 23 are labeled with an “x” to indicate that they have a built-in crossover (MDI-X). Workstations and servers can be connected to these ports with straight-through cable. Port 24 is switch-selectable (MDI-X or MDI).
ABOUT THE TIGERSWITCH 10/100 Status LEDs The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following table. Figure 1-4. Port and System LEDs Port and System Status LEDs LED Condition Status Power On Switch is receiving power. On Port has established a valid network connection. Yellow Valid 10 Mbps connection. Green Valid 100 Mbps connection. Flashing Traffic is passing through the port. FDX On Port is operating at full duplex.
ABOUT THE TIGERSWITCH 10/100 Switch Management This switch includes a built-in management agent that offers a variety of management options, including SNMP, RMON and a Web-based interface. The switch also includes an RS-232 serial port for out-of-band management. A PC may be connected to this port for configuration and monitoring purposes out-of-band via a full-handshaking null-modem cable. The management agent provides a wide range of advanced performance-enhancing features.
ABOUT THE TIGERSWITCH 10/100 port, or in-band via the Web interface, Telnet, or SNMP network management software. VLANs The TigerSwitch 10/100 supports up to 64 VLANs. A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. By segmenting your network into VLANs, you can: • Eliminate broadcast storms which severely degrade performance in a flat network.

CHAPTER 2 NETWORK PLANNING Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology.
NETWORK PLANNING Sample Applications The TigerSwitch 10/100 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 are described below. Collapsed Backbone The TigerSwitch 10/100 is an excellent choice for mixed Ethernet and Fast Ethernet installations where significant growth is expected in the near future.
NETWORK PLANNING Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type (up to 550 meters for 1 Gbps fiber). The TigerSwitch can serve as a collapsed backbone, providing direct connectivity for a widespread LAN. The Gigabit module can be used for a high-speed connection between floors in the same building, or to connect to other buildings in a campus setting. The figure below illustrates a TigerSwitch connecting multiple segments with fiber cable.
NETWORK PLANNING When you expand port-based VLANs across several switches, you need to make a separate connection for each VLAN group. This approach is, however, inconsistent with the Spanning Tree Protocol, which can easily segregate ports that belong to the same VLAN. When VLANs cross separate switches, it is therefore better to use VLAN tagging. This allows you to assign multiple VLAN groups to the “trunk” ports (that is, tagged ports) connecting different switches. Figure 2-3.
NETWORK PLANNING Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed below for Ethernet, Fast Ethernet, or Gigabit Ethernet. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.
NETWORK PLANNING Maximum Network Diameter Using Repeaters Repeater Type and Number Twisted Pair 100BASE-TX 1 Class I 200 m (656 ft.) 1 Class II 200 m (656 ft.) 2 Class II 205 m (672.4 ft.) Maximum Fast Ethernet Cable Distance Cable Type Connecting Max. Distance Twisted Pair Any two devices 100 m (328 ft.) Fiber Switch to switch, server or PC Half duplex 412 m (1,351.4 ft.) Full duplex 2 km (1.24 mi.
NETWORK PLANNING Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a 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. When a switch is connected to a hub or any kind of shared media, remember to turn off back pressure to prevent the attached port from being frequently partitioned due to the jamming packets. 3.
NETWORK PLANNING 2-8
INSTALLING CHAPTER 3 THE SWITCH Selecting a Site TigerSwitch 10/100 units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. ◆ The site should: • be at the center of all the devices you want to link and near a power outlet.
INSTALLING THE SWITCH Equipment Checklist After unpacking the TigerSwitch 10/100, check the contents to be sure you have received all the components. Then, before beginning the installation, be sure you have all other necessary installation equipment.
INSTALLING THE SWITCH Mounting A TigerSwitch 10/100 unit can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Installing Optional Modules: Before mounting the switch, be sure you install any optional modules. If you have purchased optional slide-in 1000BASE-SX media expansion modules, install these modules now, following the instructions included with the package.
INSTALLING THE SWITCH To rack-mount devices: 1. Attach the brackets to the device using the screws provided in the Bracket Mounting Kit. Figure 3-1. Attaching the Brackets 2. Mount the device in the rack, using four rack-mounting screws (not provided). Figure 3-2.
INSTALLING THE SWITCH 3. If installing a single switch only, turn to “Connecting to a Power Source” at the end of this chapter. 4. If installing multiple switches, mount them in the rack, one below the other, in any order. Desktop or Shelf Mounting 1. Attach the four adhesive feet to the bottom of the first switch. Figure 3-3. Attaching the Adhesive Feet 2. Set the device on a flat surface near an AC power source, making sure there are at least two inches of space on all sides for proper air flow. 3.
INSTALLING THE SWITCH Connecting to a Power Source To connect a device to a power source: 1. Insert the power cable plug directly into the receptacle located at the back of the device. Figure 3-4. Power Receptacle 2. Plug the other end of the cable into a grounded, 3-pin socket. Note: For International use, you may need to change the AC line cord. You must use a line cord set that has been approved for the receptacle type in your country. 3.
CHAPTER 4 MAKING NETWORK CONNECTIONS Connecting Network Devices The TigerSwitch 10/100 is designed to interconnect multiple segments (or collision domains). It may be connected to 10 or 100 Mbps network cards in PCs and servers, as well as to Ethernet and Fast Ethernet hubs, switches or routers. It may also be connected to remote devices using the optional 1000BASE-SX modules. Note: Before connecting cables, you may want to first configure the Spanning Tree Protocol to avoid network loops.
MAKING NETWORK CONNECTIONS make a connection, PCs can be connected to these ports with straight-through cable. 10BASE-T/100BASE-TX hubs and switches, on the other hand, may have either crossover (MDI-X) or straight-through (MDI) ports. For this reason, the type of cable used to connect these devices to the TigerSwitch is determined by the port on the other device, as shown in the table below. (See Appendix B for further information on cabling.
MAKING NETWORK CONNECTIONS Connecting to PCs, Servers, Hubs and Switches 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 4-1. Making Twisted-Pair Connections 2. If the device is a network card and the TigerSwitch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet (see “Wiring Closet Connections” on the next page). Otherwise, attach the other end to an available port on the switch. 3.
MAKING NETWORK CONNECTIONS 5. As each connection is made, the green Link LED (on the TigerSwitch) corresponding to each port will light to indicate that the connection is valid. Wiring Closet Connections Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follows. 1.
MAKING NETWORK CONNECTIONS Fiber Optic Devices An optional slide-in 1000BASE-SX module may be used for a backbone connection between switches, or for connecting to a high-speed server. Each fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an SC connector at both ends. If you need to connect to a device with 62.5/125 micron cable that has ST-type connectors, SMC provides an optional SC-ST Converter (Part Number: 99-012034-091).
MAKING NETWORK CONNECTIONS Figure 4-3. Making SC Port Connections 4. As a connection is made, check the Activity LED on the switch’s front panel for the corresponding module to be sure that the connection is valid. Note: If you use the optional SC-ST Converter, be sure to connect the converter’s Tx (Rx) port to the Rx (Tx) port on the other device. The 1000BASE-SX fiber optic ports operate at 1 Gbps full duplex, with auto-negotiation of flow control.
APPENDIX A TROUBLESHOOTING Diagnosing Switch Indicators Troubleshooting Chart Symptom Action Power LED is Off • Internal power supply has failed or is disconnected. • Check connections between the switch, the power cord, the wall outlet. • If the switch is installed in a rack, check the connections to the punch-down block and patch panel. • Contact SMC Tech Support. Power LED is Flashing • The switch is either downloading firmware or running the Power-On Self-Diagnostics Test (POST).
TROUBLESHOOTING Power and Cooling Problems If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the unit are unobstructed and running prior to shutdown.
TROUBLESHOOTING Note: You can configure the management agent to accept from one to four simultaneous Telnet sessions. If the maximum number of sessions already exists, an additional Telnet connection will not be able to log into the system.

CABLES Twisted-Pair Cable and Pin Assignments Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards. For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.
CABLES 100BASE-TX/10BASE-T Pin Assignments With 100BASE-TX/10BASE-T cable, pins 1 and 2 are used for transmitting data, and pins 3 and 6 for receiving data. RJ-45 Pin Assignments Pin Number Assignment1 1 Tx+ 2 Tx- 3 Rx+ 6 Rx- 1: The “+” and “-” signs represent the polarity of the wires that make up each wire pair. Straight-Through Wiring If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through.
CABLES Crossover Wiring If the twisted-pair cable is to join two ports and either both ports are labeled with an “x” (MDI-X) or neither port is labeled with an “x” (MDI), a crossover must be implemented in the wiring.
CABLES Console Port Pin Assignments The DB-9 serial port on the switch’s front panel is used to connect to the switch for out-of-band console configuration. The on-board menu-driven configuration program can be accessed from a terminal, a PC running a terminal emulation program, or from a remote location via a modem connection. The pin assignments used to connect to the serial port are provided in the following tables. Figure B-2.
