CHAPTER 1 ABOUT THE TIGERSWITCH 10/100 Overview SMC’s TigerSwitch™ 10/100 is a Fast Ethernet switch with 48 10BASE-T/100BASE-TX ports, plus two slots for optional slide-in 100BASE-FX or 1000BASE-SX modules. There is also an SNMP-based Network Management Module installed in the rear panel. This module supports both in-band and out-of-band access for managing the switch. Figure 1-1.
ABOUT THE TIGERSWITCH 10/100 Figure 1-2. Rear Panel Figure 1-3. Optional 100BASE-FX and 1000BASE-SX Modules 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.
ABOUT THE TIGERSWITCH 10/100 Management Options This switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status. It also includes a Network Management Module that allows the switch to be managed in-band via SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or remotely via Telnet. The switch also provides a serial port on the rear panel for out-of-band management.
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. Port and System Status LEDs LED Condition Status Power On Switch is receiving power. RDP On Redundant power is on, and the RPU is in backup or active mode. Off Redundant power is off or has failed. On Agent is operational. On Amber Port has established a valid 10 Mbps connection.
ABOUT THE TIGERSWITCH 10/100 Network Management Module Figure 1-4. Network Management Module This switch includes a Network Management Module on the rear panel. It offers a variety of management options, including SNMP, RMON and a Web-based interface. This module also includes an RS-232 port for out-of-band management. 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 fullhandshaking null-modem cable.
ABOUT THE TIGERSWITCH 10/100 Spanning Tree Protocol The TigerSwitch 10/100 supports 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, this 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.
ABOUT THE TIGERSWITCH 10/100 Multicast Switching Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with normal network traffic and to guarantee real-time delivery by setting the required priority level for the designated VLAN. The switch uses IGMP Snooping and IGMP to manage multicast group registration.
ABOUT THE TIGERSWITCH 10/100 Figure 1-6. Single-Port 1000BASE-SX Module (SMC6900G) Using fiber optic cable, the 1000BASE-SX port can be connected to a remote site up to 550 m (1805 ft) away. The 1000BASE-SX Gigabit module operates at 1 Gbps, with support for auto-negotiation of duplex mode and flow control. This module is fitted with an SC connector, but you can attach an ST plug to the switch using the SC-ST Converter (Part Number: 99-012034-091)..

ABOUT THE TIGERSWITCH 10/100 Performance ◆ Transparent bridging ◆ Aggregate bandwidth up to 13.
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 Central Wiring Closet With up to 52 ports on the switch, the TigerSwitch 10/100 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 are providing 100 Mbps connectivity for up to 48 segments through SMC’s TigerStack™ II 10/100 hubs. In addition, the switch is also connecting servers at 200 Mbps.
NETWORK PLANNING Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type (up to 2 kilometers for 100 Mbps fiber at full duplex, or up to 550 meters for 1 Gbps fiber). The TigerSwitch can serve as a collapsed backbone, providing direct connectivity for a widespread LAN. The 100 Mbps fiber modules (with two ports per module) can be used to interconnect remote Fast Ethernet segments.
NETWORK PLANNING Making VLAN Connections VLANs can be based on port groups, or each data frame can be explicitly tagged to identify the VLAN group it belongs to. When using port-based VLANs, ports can either be assigned to any number of groups. Port-based VLANs are suitable for small networks. A single switch can be easily configured to support several VLAN groups for various organizational entities (such as Finance and Marketing).
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 100 Mbps Fast Ethernet Collision Domain SMC 3-2 Rule for Class II Repeaters Between any two PCs or other stations in the same 100BASE-TX collision domain, there may be: • up to 3 link segments and • up to 2 Class II repeaters (hubs) SMC 2-1 Rule for Class I Repeaters Between any two PCs or other stations in the same 100BASE-TX collision domain, there may be: • up to 2 link segments and • up to 1 Class I repeater (hub) Maximum Network Diameter Using Repeaters Repeater Type and Number Twis
NETWORK PLANNING 10 Mbps Ethernet Collision Domain SMC 5-4-3 Rule Between any two PCs or other stations in the same 10 Mbps collision domain, there may be: • up to 5 link segments in series, • up to 4 repeaters (hubs), • up to 3 populated cable segments, that is, segments attached to two or more PCs (coax networks only).* * The remaining two segments are unpopulated; these are known as inter-repeater links or IRLs.
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 2-10
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 an optional slide-in 100BASE-FX or 1000BASE-SX media expansion module, 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. 5. If also installing RPUs, mount them in the rack below the other devices. 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.
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 100BASE-FX or 1000BASE-SX modules. Note: Before connecting cables, you may want to first configure the Spanning Tree Protocol to avoid network loops.
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. 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).
MAKING NETWORK CONNECTIONS 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. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel. 2.
MAKING NETWORK CONNECTIONS Fiber Optic Devices An optional slide-in 100BASE-FX module may be used for backbone and long distance connections. A 1000BASE-SX module may also 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.
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 100BASE-FX fiber optic ports operate only at 100 Mbps, full duplex. You can run a fiber link up to 1.24 miles (2 kilometers).
MAKING NETWORK CONNECTIONS 4-6
APPENDIX A TROUBLESHOOTING Diagnosing Switch Indicators Troubleshooting Chart Symptom Action Power LED is Off • Internal or redundant power supply has failed or is disconnected. • Check connections between the switch, the power cord, the wall outlet, and the RPU if you are using one. • If the switch is installed in a rack, check the connections to the punch-down block and patch panel. • Contact SMC Tech Support.
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 rear 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.
