2-1 Chapter 2: Network Planning Introduction to Switching A network switch allows simult aneous transmi ssion of multiple packet s via non-crossbar switchin g.
2-2 Network Planning 2 Application Examples The Gigabit Etherne t Switches are not only designed to segment your network, but also to provide a wide range of opti ons in setting up net work connections and li nking VLANs or IP subnets. Some typical applications are des cribed below .
2-3 Application Exa mples 2 Network Aggregation Plan With 24 or 48 p arallel bridging port s (i.e., 24 or 48 distinct collision domains), a Gigabit swi tch stack ca n collaps e a complex netwo rk down into a single ef ficient bridged node, inc reasing overall bandwid th and throughput.
2-4 Network Planning 2 Remote Connections with Fiber Cable Fiber optic technology allo ws for longer cabl ing than any oth er media type. A 1000BASE-SX (MMF) link can connect to a sit e up t o 550 meters away , a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-LH l ink up to 70 km.
2-5 Application Exa mples 2 Making VLAN Connections These switches support VLANs which can be used to organize any group of network nodes into separate broadc ast domains. VLANs con fine broadcast traf fic to the originatin g group, and can el iminate broadcast s torms in large networks.
2-6 Network Planning 2 Using Layer 3 Routing VLANs can signif icantly enhance n etwork performance and securi ty . However , if you use conventiona l routers to interconnect VLANs, you can l ose most of your performance adva ntage.
2-7 Application Not es 2 Application Notes 1. Full-duplex op eration only appli es to point-to-poi nt access (such as when a switch is att ached to a workstat ion, server or another switch). When the switch is connecte d to a hub , both devices must opera te in half-duplex mode.

3-1 Chapter 3: Installing the Switch Selecting a Site Switches can be mount ed in a st andard 19 -inch equipment rack or on a flat surface . Be sure to follow the guid elines below when choosi ng a location. • The site should: - be at the center of all t he devi ces you want to link and near a power outlet.
3-2 Installing th e Switch 3 Figure 3-1 RJ-45 Connecti ons Equipment Checklist After unp acking the switch, check the content s to be sure you have received all the component s. Then, be fore beginning the inst allation, be s ure you have all o ther necessary inst allation equipment.
3-3 Mounting 3 Mounting A switch unit can be mo unted i n a s t an dard 1 9-inc h equ ipme nt ra ck or on a des kto p or shelf. Mounti ng instructions for each t ype of site follow .
3-4 Installing th e Switch 3 2. Mount the device i n the rack, using four rack-mounting screws (not provide d). Figure 3-3 Installing the Switch in a Rack 3. If inst alling a single switch only , turn to "Connecting to a Power Source" at the end of this chapt er .
3-5 Installing an Optional Module i nto the Switch 3 3. If inst alling a single switch only , go to "Connectin g to a Power Source" at the end of this chapt er . 4. If inst alling multi ple switches, at tach fo ur adhesive feet to each one .
3-6 Installing th e Switch 3 Installing an Optional SFP Transceiver Figure 3-6 Inserting an SF P Transceiver into a Slot These switches support 100 0BASE-SX and 1000BASE-LX, and 1000BASE-LH SFP-compati ble transceivers. T o in stall an SFP transcei ver , do the following: 1.
3-7 Connecting Switc hes in a Stack 3 Connecting Switches in a Stack Figure 3-7 sh ows how the stack cables are connected between switches in a stack. Each stacki ng connection is a 48 Gbps f ull -duplex high-speed serial link using propriet ary stacking cables.
3-8 Installing th e Switch 3 5. Select the Mast er unit in the st ack by pressing th e Master bu tton in o n only on e of the switc hes. Only one switch in the stac k can operate as the Master , all other unit s operate in slave mode.
3-9 Connecting to th e Console Port 3 3. Check the front -panel LEDs as the devi ce is powered on to be sure the Power LED is on. I f not, check t hat the power cable is correctly plugged in.
