Chapter 1: Introduction Overview The TigerSwitch 10/100/1000, SMC8126L2, is an intelligent Layer 2 switch with 26 10/100/1000BASE-T ports, four of which are combination ports* that are shared with four SFP transceiver slots (see Figure 1-1, Ports 21-24). The SMC8126L2 includes an SNMP-based management agent embedded on the main board, which supports both in-band and out-of-band access for managing the switch.
1 Introduction Switch Architecture The SMC8126L2 employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. It also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. This switch uses store-and-forward switching to ensure maximum data integrity.
Description of Hardware 1 Description of Hardware 10/100/1000BASE-T Ports The SMC8126L2 contains 26 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. 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 “1000BASE-T Pin Assignments” on page B-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. These switches have, therefore, been recognized as one of the most important building blocks for today’s networking technology.
2 Network Planning Application Examples The SMC8126L2 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 SMC8126L2 is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.
Application Examples 2 Network Aggregation Plan With 26 parallel bridging ports (i.e., 26 distinct collision domains), a switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10/100/1000BASE-T ports are providing 1000 Mbps connectivity through Layer 2 switches. In addition, the switches are also connecting several servers at 1000 Mbps. 25 26 Server Farm 10/100/1000 Mbps Segments ... ...
2 Network Planning Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-ZX link up to 100 km. This allows a switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
Application Examples 2 Making VLAN Connections This switch support VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs.
2 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. For network applications that require routing between dissimilar network types, you can attach these switches directly to a multi-protocol router. 3.
Chapter 3: Installing the Switch Selecting a Site The SMC8126L2 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.
3 Installing the Switch RJ-45 Connector Figure 3-1 RJ-45 Connections Equipment Checklist After unpacking the switch, 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.
Mounting 3 Mounting This switch can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Rack Mounting Before rack mounting the switch, pay particular attention to the following factors: • Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range. (See page C-1.
3 2. Installing the Switch Mount the device in the rack, using four rack-mounting screws (not provided). Figure 3-3 Installing the Switch in a Rack 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 3-4 Attaching the Adhesive Feet 2.
Installing an Optional SFP Transceiver 3 3. If installing a single switch only, go to “Connecting to a Power Source” at the end of this chapter. 4. If installing multiple switches, attach four adhesive feet to each one. Place each device squarely on top of the one below, in any order. Installing an Optional SFP Transceiver Figure 3-5 Inserting an SFP Transceiver into a Slot The switch supports 1000BASE-SX and 1000BASE-LX, and 1000BASE-ZX SFP-compatible transceivers.
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 socket located at the back of the device. 100-240V~50-60Hz 1.5A Figure 3-6 Power Socket 2. Plug the other end of the cable into a grounded, 3-pin, AC power source. 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 SMC8126L2 is designed to interconnect multiple network segments (or collision domains). It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. It may also be connected to devices using optional SFP transceivers. Twisted-Pair Devices Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
4 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 PC card and the switch 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 “Network Wiring Connections” on page 4-2.) Otherwise, attach the other end to an available port on the switch.
Fiber Optic SFP Devices 4 Equipment Rack (side view) Network Switch w it c h 10 /1 0 0 6724L3 ES4524C Punch-Down Block Patch Panel Wall Figure 4-2 Network Wiring Connections Fiber Optic SFP Devices An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX or 1000BASE-ZX) can be used for a backbone connection between switches, or for connecting to a high-speed server. Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends.
4 Making Network Connections 1. Remove and keep the LC port’s rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics. 2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port. 3.
Connectivity Rules 4 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) or Category 6 cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5.

Appendix A: Troubleshooting Diagnosing Switch Indicators Table A-1 Troubleshooting Chart Symptom Action Power LED is Off • Check connections between the switch, the power cord, and the wall outlet. • Contact your dealer for assistance. Power LED is Amber • Internal power supply has failed. Contact your local dealer for assistance. Diag LED is Amber • Power cycle the switch to try and clear the condition. • If the condition does not clear, contact your local dealer for assistance.
A Troubleshooting In-Band Access You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software tools. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address.
Appendix B: Cables Twisted-Pair Cable and Pin Assignments For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. Caution: DO NOT plug a phone jack connector into any RJ-45 port.
