CHAPTER 1 ABOUT THE TIGERSWITCH 10/100 Overview SMC’s TigerSwitch™ 10/100 is an intelligent Fast Ethernet switch with 48 10BASE-T/100BASE-TX ports and two 10/100/1000BASE-T combo ports that operate in combination with 2 Small Form Factor Pluggable (SFP) transceiver slots. This switch can easily tame your network with full support for Spanning Tree Protocol, Multicast Switching, Virtual LANs, and Layer 2/3/4 CoS services.
ABOUT THE TIGERSWITCH 10/100 Switch Architecture The TigerSwitch 10/100 employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. Switching Method The switch uses store-and-forward switching to ensure maximum data integrity.
OVERVIEW 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, 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.
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.
DESCRIPTION OF HARDWARE Description of Hardware 10BASE-T/100BASE-TX Ports These are dual-speed RJ-45 ports. Because all ports on this switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. (See“100BASE-TX/10BASE-T Pin Assignments” on page B-3.
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 1-2.

ABOUT THE TIGERSWITCH 10/100 Optional Redundant Power Unit SMC provides an optional Redundant Power Unit (RPU), SMCRPS600W, that can supply power to the switch in the event of failure of the internal power supply. Power Supply Receptacles There are two power receptacles on the rear panel of the switch. The standard power receptacle is for the AC power cord. The receptacle labeled “DC Input” is for the optional Redundant Power Unit (RPU). Figure 1-3.

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.
SAMPLE APPLICATIONS Central Wiring Closet With 50 parallel bridging ports (i.e., 50 distinct collision domains), 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. In addition, the switch is also connecting servers at 200 Mbps. TigerSwitch 10/100 Server Farm 10/100 Mbps Segments ... ...
NETWORK PLANNING Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-LX SFP transceiver link can connect to a site up to 5 km away. This allows the TigerSwitch 100 to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. A Gigabit SFP transceiver can also be used for a high-speed connection between floors in the same building, or to connect to other buildings in a campus setting.
SAMPLE APPLICATIONS 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 one specific group or to all 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, and 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.

APPLICATION NOTES 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 jamming packets from being propagated thoughout the hub. 3.

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 network cards in PCs and servers, or to hubs, switches or routers. Note: Before connecting cables, you may want to first configure the Spanning Tree Protocol to avoid network loops. Refer to the Management Guide for more information.
MAKING NETWORK CONNECTIONS Note: If auto-negotiation is disabled for an RJ-45 port, the auto-MDI/ MDI-X pin signal configuration is also disabled. See Appendix B for further information on cabling. Caution: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards. Connecting to PCs, Servers, Hubs and Switches 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.
TWISTED-PAIR DEVICES 3. 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 follow. 1.

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.
TWISTED-PAIR CABLE AND PIN ASSIGNMENTS 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.
CABLES 1000BASE-T Pin Assignments 1000BASE-T ports switch support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.
TWISTED-PAIR CABLE AND PIN ASSIGNMENTS 1000BASE-T Cable Requirements All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5.
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.
