2-1 Chapter 2 : Network Planning Introduction to Switching A network switch a llows simult a neous tr ansmission of multip le packet s via non-cro ssbar swit ching. This m eans tha t it can partition a netw ork more efficiently than bridg es or routers.
Network Planni ng 2-2 2 Application Examples The Ma trix V -Se ries V2H124- 24P switch is not on ly designe d to segment yo ur network , but also to provi de a wide rang e of options in setting up n etwork connect ions. So me typical applications ar e describe d below .
Application Examp les 2-3 2 Network Aggregation Pla n With 24 parall el bridging p orts (i.e., 24 distinct collision dom ains), the M atrix V -Ser ies PoE sw itch can co llapse a comple x network dow n into a single efficient bridged nod e, increas ing overall bandwidth and th roughpu t.
Network Planni ng 2-4 2 Remote Connections with Fiber Cable Fiber optic t echnology allows for lon ger cabling th an any other media type . Using a 1000BASE- SX multimode fiber (MMF) SFP transceiver , you c an run a link up to 550 m. A 1000B ASE-LX single-mod e fiber (SMF) link can run up to 5 km.
Application Examp les 2-5 2 Making VLAN Connecti ons This switc h supports VLANs w hich can be used to organi ze any group of network node s into sep arate br oadc ast doma ins. VL ANs conf ine br oadcast traf fic to the ori ginati ng gr oup, an d can el iminat e br oadca st stor ms in la rge net work s.
Network Planni ng 2-6 2 Application Notes 1. Ful l-du plex oper ati on only appl ies to po int- to-poin t acces s (suc h as when a switch is attached to a workstati on, serv er or an other switch). When the sw itch is conne cted to a hub, bot h devices m ust operat e in half-dup lex mode.
3-1 Chapte r 3: Insta lling the Switch Selecting a Sit e Matrix V-Series V2H12 4-24P u nits can be mounted in a standard 19 -inch equ ipment rack or on a flat surface. Be sure to follow the guidelines below when ch oosing a location . • The site s hould: - be at the cent er of all the devices you wan t to link and nea r a power out let.
