SwitchArchitecture
Theswitchincorporatesawire‐speed,non‐blockingswitchingfabric.Thisallowswire‐speedtransportofmultiple
packetsatlowlatencyonallportssimultaneously.Theswitchalsofeaturesfull‐duplexcapabilityonallports,
whicheffectivelydoublesthebandwidthofeachconnection.Thisswitchusesstore‐and‐forwardtechnologyto
ensuremaximumdataintegrity.Withthistechnology,theentirepacketmustbereceivedintoabufferand
checkedforvaliditybeforebeingforwarded.Thispreventserrorsfrombeingpropagatedthroughoutthe
network.
NetworkManagementOptions
TheswitchcanalsobemanagedoverthenetworkwithawebbrowserorTelnetapplication.Theswitchincludes
abuilt‐innetworkmanagementagentthatallowsittobemanagedin‐bandusingSNMPorRMON(Groups1,2,3,
9)protocols.SeetheWebUserGuideforadetaileddescriptionofthemanagementfeatures.

Mounting
Theswitchcanbemountedinastandard19‐inchequipmentrackoronadesktoporshelfasfollows.
Rack Mounting
Beforerackmountingtheswitch,verifythese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(‐20°to+60°C).
•MechanicalLoading:Donotplaceanyequipmentontopofarack‐mountedunit.
•CircuitOverloading:Besurethatthesupplycircuittotherackassemblyisnotoverloaded.
•Grounding:Rack‐mountedequipmentshouldbeproperlygrounded.
ToRack‐mountDevices:(Optional)
1. AttachthebracketstothedeviceusingthescrewsprovidedintheMountingAccessory.
 
2. Mountthedeviceintherack(viaRack‐Mountkit),usingfourrack‐mountingscrews(notprovided).Besureto
securethelowerrack‐mountingscrewsfirsttopreventthebracketsbeingbentbytheweightoftheswitch.
3. Ifinstallingasingleswitchonly,turnto“Connection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rubberfeettothebottomofthefirstswitch.

2. SetthedeviceonaflatsurfacenearanACpowersource,makingsurethereareatleasttwoinchesofspace
onallsidesforproperairflow.
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.

EthernetCabling
Toensureproperoperationwheninstallingtheswitchintoanetwork,makesurethatthecurrentcablesare
suitableforyouroperatingenvironment.Checkthefollowingcriteriaagainstthecurrentinstallationofyour
network:
•Protectionfromradiofrequencyinterferenceemissions.
•Electricalsurgesuppression.
•Separationofelectricalwiresanddatabasednetworkwiring.
•Safeconnectionswithnodamagedcables,connectorsorshields.
WARNING:Themini‐GBICsareClass1laserdevices.Avoiddirecteyeexposuretothebeamcomingfrom
thetransmitport.
