Power Consumption and Cooling Requirements
Thepowerandcoolingrequirementsforthelibrarydependonthenumber
andtypeofdrivesinstalled.Thefollowingtableprovidesthemaximum
powerconsumptionandheatloadforthebaselibraryandforeach
additionalcomponentaddedtothebaselibrary.Usethisinformationto
calculatethetotalmaximumpowerconsumptionandheatloadvalues,
whichcanbeusedtobuildapowerbudgetforthelibrary.
AllvaluesaremeasuredattheACinputandincludepowersupply
