1-1 Chapter 1: Introduction Overview The T igerSwitch 10/100/10 00, SMC8126L2, is an intelligent Lay er 2 switch with 26 10/100/1000BASE-T port s , four of which are comb ination port s * t hat are s hared with four SFP transceiver slots (see Figu re 1-1, Ports 21-24 ).
Introduction 1-2 1 Switch Architecture The SMC8126L2 employs a wire-sp eed, non -bloc kin g swit chi ng fab ri c. Th is p ermit s simulta neous wire-speed tr ansport of multiple p ackets at low latency on al l ports. It also features full -dupl ex capability on all port s, which effectively doubles t he bandwidth of each connection.
Description of Hardware 1-3 1 Description of Hardware 10/100/1000BASE-T Ports The SMC8126L2 contai ns 26 RJ-45 ports that operate at 10 Mbp s or 100 Mbps, half or full duplex, or at 1000 Mbps, full dupl ex.
Introduction 1-4 1 Figure 1-4 System LEDs Table 1-1 Port Status LEDs Label Color Description Link/Activity/ Speed On/Flashing Amber Port has a valid link at 10 o r 100 Mbps. F lashing indicates activit y . On/Flashing Green Port has a valid link at 1000 Mbps.
Features and Benefi ts 1-5 1 Power Supply Socket The power socket is on the rear pane l. The stand ard power socket is for the AC power cord . Figure 1-5 Power Supply Socket Features and Benefits Connectivity • 26 10/100/1000 Mbp s ports for easy Gigabi t Ethernet integrat ion and for protection of your investment in legacy LAN equipment.
Introduction 1-6 1 Management • “At-a-glance” LEDs for easy troubleshoo ting • Network management agent: - Manages switch in-band or out-of- band - Supports console, Telnet, SSH, SNMP v1/v2c/v.
2-1 Chapter 2: Network Planning Introduction to Switching A network switch al lows simult aneous transmission of mult iple p ackets v ia non-crossbar switching.
2-2 Network Planning 2 Application Examples The SMC8126L2 is not only design ed to segment your network, but also to provide a wide range of options in sett ing up network connections.
2-3 Application Exampl es 2 Network Aggregation Plan With 26 paral lel bridging port s (i.e., 26 distinct col lision domains), a switch can collapse a complex network down into a single ef ficient bridged node, increasing overall bandwid th and throughput.
2-4 Network Planning 2 Remote Connections with Fiber Cable Fiber optic tec hnology allows for longer c abling than a ny other media t ype. A 1000BASE-SX (MMF) link can connect to a site up t o 550 met ers away , a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-ZX lin k up to 100 km.
2-5 Application Exampl es 2 Making VLAN Connections This switch support VLANs which can be used to organi ze any group of network nodes into se parate broadc ast domains. VLANs confine broadcast traff ic to the originating g roup, and can el iminate broadcast storms in large ne tworks.
2-6 Network Planning 2 Application Notes 1. Full-duplex operat ion only appli es to point-t o-point access (such as when a switch is attac hed to a workstation, server or another switch). When the switch is connected to a hub , bot h devices must opera te in half-duplex mode.
3-1 Chapter 3: Installing the Switch Selecting a Site The SMC8126L2 can be mounted in a st andard 19-inch equipment rack or on a flat surface. Be sure to foll ow the guide lines below wh en choosing a location. • The site should: - be at the center of all the devices you want to link and near a power outlet.
3-2 Installing the Switch 3 Figure 3-1 R J-45 Connections Equipment Checklist After unpa ckin g the switch, check the content s to be sure you have received all the components . Then, before begi nning the inst allation, be sure you have all o t her necessary inst allation equipment.
3-3 Mounting 3 Mounting This switch can be mounted in a st andard 19-inch equ ipment rack or on a de sktop or shelf. Mount ing instructions for each type of site foll ow .
3-4 Installing the Switch 3 2. Mount the device in the rack, usi ng four rack-mounting screws (not provide d). Figure 3-3 Installing the Switch in a Rack 3. If install ing a single switch only , turn to “Connecting to a Power Sourc e” at th e end of this chapter .
3-5 Installing an Optiona l SFP Transceiver 3 3. If inst alling a single switch only , go to “Connecting to a Power Source” at the end of this chapter . 4. If inst alling multipl e switches, att ach four adhesi ve feet to each one. Pl ace each device squarely on top of t he one below , in any order .
3-6 Installing the Switch 3 Connecting to a Power Source T o connect a device to a power source: 1. Insert the po wer cable plug directly into the socket l ocated at th e back of the device. Figure 3-6 Power Socket 2. Plug the other end of the c able into a ground ed, 3-pin, AC power source.
3-7 Connecting to the Con sole Port 3 Wiring Map for Serial Cable The serial port’ s configuration requirement s are as follows: • Default Baud rate—9, 600 bps • Character Size—8 Characters .
3-8 Installing the Switch 3.
4-1 Chapter 4: Making Network Connections Connecting Network Devices The SMC8126L2 is designed to int erconnect multiple network segment s (or collision domains). It can be connected to network cards in PCs and servers, as well as t o hubs, switches or route rs.
4-2 Making Network Conne ctions 4 Connecting to PCs, Servers, Hubs and Switche s 1. Attach one end of a twisted-pa ir cable segment to the devic e’s RJ -45 connector .
4-3 Fiber Optic SFP Devices 4 Figure 4-2 Network Wir in g Connections Fiber Optic SFP Devices An optional Gigabit SFP t r ansceiver (1000BASE-SX, 1000BASE-LX or 1000BASE-ZX) can be used for a backbone connectio n between switches, or for connecting to a high-sp eed server .
4-4 Making Network Conne ctions 4 1. Remove and keep the LC port’ s rubber cover . When not connected to a fiber cable, the rubber cove r should be replaced to pro tect the optics.
4-5 Connectivity Rules 4 1000BASE-T Cable Requirements All Category 5 UTP cables that are used for 100BASE-TX con nections should also work for 1000BASE-T , providing that a ll four wi re p ai rs are con nected.
4-6 Making Network Conne ctions 4 10 Mbps Ethernet Collision Domain Cable Labeling and Connection Records When planning a network inst allation, it is essential to label the opposing ends of cables and to record where each cable is co nnected.
A-1 Appendix A: Troubleshooting Diagnosing Switch Indicators Power and Cooling Problems If the power indicator doe s not turn on when the power cord is plugged in, you may have a problem with the power out let, power cord, or inte rn al power supply .
A-2 Troubleshooting A In-Band Access Y ou can access the management agent in the switch from anywhere wit hin the attache d network using T elnet, a W eb browser , or other network manag ement software too ls. However , you must first configure the switch with a valid IP addres s, subnet mask, and defaul t ga teway .
B-1 Appendix B: Cables Twisted-Pair Cable and Pin Assignments For 10/100BASE-TX connections, the twi s ted-pair ca ble must have two pai rs of wires. For 1000BASE-T connect ions the twis ted -pair cable must have f our pairs of wires. Each wi re pai r is identif ied by two d ifferen t colors.
B-2 Cables B Straight-Through Wiring If the twisted-p air cable is to join two ports and onl y one of the ports has an in ternal crossover (MDI-X), the two pairs of wires must be straight-through.
B-3 T wisted-Pair Cable a nd Pin Assignments B Y ou must connect all four wi re pairs as shown in th e following diagram to suppo rt Gigabit Ethernet connec tions.
B-4 Cables B Cable Testing for Existing Category 5 Cable Instal led Category 5 cabling must p ass tests for Attenuation, Near-End Crosst alk (NEXT), and Far-End Crosstal k (FEXT). This cable testing informati on is specified in the ANSI/TIA/EIA-TSB-67 st andard.
