SafetyInstructionsforRackMountInstallations
Theinstructionsbelow(orsimilar)areintendedforrackmountinstallationenvironments:
1. ElevatedOperatingAmbientTemperature:ifinstalledinaclosedormulti‐unitrackassembly,theoperatingambient
temperatureoftherackenvironmentmayexceedroomambient.Installtheequipmentinanenvironment
compatiblewiththemaximumambienttemperature(Tma)specified.
2. ReducedAirFlow:installtheequipmentinaracksothattheamountofairflowrequiredforsafeoperationisnot
compromised.
3. MechanicalLoading:Mounttheequipmentintheracksothatahazardousconditiondoesnotoccurduetouneven
mechanicalloading(weightdistribution/rackbalance).
4. CircuitOverloading:giveconsiderationtotheconnectionoftheequipmenttothesupplycircuitandtheeffectthat
overloadingofthecircuitsmighthaveonovercurrentprotectionandsupplywiring.Considerallequipment
nameplateratingswhenaddressingthisconcern.
5. ReliableEarthing:maintainreliableearthingofrack‐mountedequipment;payparticularattentiontosupply
connectionsotherthandirectconnectionstothebranchcircuit(e.g.,useofpowerstrips).

FiberCableHandling&Installation
HandlingFiberCables
Accurateandrepeatabledatatransmissionsrequirecleanfiber‐opticconnections;therefore,inspecttheendsofall
connectorsfordustorimperfections.Toachievethebestpossibleperformance,followtheseguidelines:
• Topreventdamage,keeptheconnectors’protectivecoveronwhennotinuse.
• Usecareinhandlingallfiber‐opticconnectors.
• Visuallyinspectfiberendsforsignsofdamage.
• Alwayscleanandinspectfiberconnectorspriortomakingaconnection.
InstallingFiberCables
Toinstallthefibercables,dothefollowing:
1.Removetheprotectivecoverfromtheport.SeeFigure9.

Figure9:LCPortandDustCover

2.Locatea2‐strandfibercablewiththeappropriatemaleconnectorsinstalledonbothends.
3.CarefullyinsertthefibercableintotheCWDMandthedevice,asshowninFigure10.
