Twopowersupplymodulesarerequiredforredundancy.Eachpow ersupplycan
beconnectedtoaseparatecircuittomitigatetheriskofdown‐timeduringa
localizedpowerfailure.Whenusedinaredundantconfiguration,thedualpow er
supplieshaveaload‐sharingcapabilitythatenableseachpowersupplyto
operate
atapproximately50percentoffullload.
Usingredundantpowercanminimizethepowerdisruptionduringapowersupply
failureandextendtheexpectedlifetimeofeachpowersupplybyoperating
normallyinaconservativepowermode.
