Chapter1Introduction
Overview
The GigabyteGN-GT8Sisapowerful,high-performance,FastEthernetSwitch,which
actsastrafficcontrollerfor8highways toconnectyournetworks tootheroutside networks.
With8GigabitEthernetuplinkports,the GigabitSwitchcan automaticallynegotiate
withthe connected partnersforthe networkspeed and duplexmode.It isidealformicro-
segmenting large networks intosmaller,connected subnetsforimproved performance,
enabling bandwidth-demanding multimedia,imaging and databaseapplications.Moreover,
the 10/100/1000Mbpsauto-sensing abilityprovidesaneasy waytomigrate10Mbpsto
100Mbpsand 1000Mbpsnetworkwithease.Compared tothe shared 10Mbps,100Mbps
or1000Mbpsnetworks,the GigabitSwitchdeliversadedicated 10/100/1000Mbpscon-
nectiontoeveryattached clientwithno bandwidthcongestion issuesand the mostcost-
effectivewaytoinvestinyournetwork’s performanceinthe long run.
Store-and-forwardswitching mode guaranteeslowlatency,pluseliminatesall network
errors,including runtand CRC errorpackets.Toworkunderfullduplexmode,transmission
and receptionofthe framescanoccursimultaneouslywithoutcausing collisions,aswellas
doubling the networkbandwidth.
The GigabitSwitchusing plug-n-playwithoutneeding anysoftwaretoconfigure,and is
alsofullycompliantwithall kindsofnetworkprotocols.Moreover,the abundantdiagnostic
LEDson the front-panelprovide the operating statusofindividualportsand the entire
system.
