Fan Module Description
TheFanModuleconsistsofasheetmetaltraytha tholdsfourfansratedatanominal–48VDC.
TheFanModuleismountedfromthefrontoftherackandisinstalledintothetopslotofthe
TotalAccess5000Chassis.TheFanModuleisdesignedtoprovideforced
airventilationto
coolafullypopulatedTotalAccess5000Chassis.
Powerissuppliedtothe FanModulethroughtwoindependentcircuitsthatarecontrolledasa
group.Eachcircuitsuppliespowertotwofans,whichareconnectedinparallel.Whenfully
inserted,theFanModuleconnectstotheSMIO3.
TheSMIO3routespowerandserialcommu‐
nicationsfromtheswitchmoduletotheFanModule.Thefanmicroprocessorsamplesthe
speedofeach fanand reportsanalarmconditionforfanfailureoreminentfanfailure.
Installation Steps
ToinstalltheFanModule,completethefo llowing:
1. PushtheFanModulefirmlyintothetopslotofthechassis(seeFigure2‐2).
