Determine the Power Consumption of the CAP M
UsethepowerconsumptionmatrixinTable5tocalculatepowerconsumptionforaCAPM,where
• theconsumptionnumbersareattheCAPMpowerinputsanddonotaccountforfeedlosses
• themaximumconsumptionnumbersinTable5donotincludethepowerconsumedbyanyattached
auxiliarydevices.BothCAPMpowerconsumptionandauxiliarydevicepowermustbeincludedwhen
calculatingfeedlosses.
Determine the Mounting Site
Whendecidingonasuitablemountingsite,observethefollowingrules;referalsoto"MountingOrientation”
onpage24.
• TheCAPMissuitableforinstallationindoorsoroutdoors.
• UsetheweightslistedinTable6todetermineasitethatcanbeartheweightoftheCAPMthatisbeing
installed,where:
– The“MaximumLiftWeight”isthehighestweightthatmustbeliftedduringinstallation.(Aninstaller
shouldlifttheCAP
Mcomponentsoneatatime,notawhollyconfiguredCAPM.)
– The“TotalHangingWeight”istheweightoftheCAPM,includingtheweightoftheMountingBracket,
minustheweightoftheexternalcablesandconnectors,thatthemountingsitemustbeableto
support.
• UsethedimensionsshowninFigure4onpage17forSingleMountandFigure5onpage18forDual
Mount.

1 Does not include SFP+ Module consumption. Can support up to 3W (more with engineering
consultation) maximum total SFP+ Module consumption. Typical installation (sufficient for SM up to
10km or MM) would be 0.8W typical, 1.0W max for each SFP+ Module.
Mains power must be interruptible with an external delay-actions mains breaker. For the Mains breaker,
observe the following recommendations.
• For the AC power supply, 120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50 / 60 Hz AC
service is needed, i.e. the external AC breaker should be 20 Amps max. for 120-Volt service or 13 to
16 Amps for 240-Volt service.
• For the DC power supply, observe the local regulations of the DC service provider.
