Power specifications
The input voltage is a function of the country-specific input voltage to Enterprise storage system
rack power distribution units (PDUs). Table 34 (page 113) defines the AC input power available to
the drive enclosure power supplies.
CAUTION: The AC power distribution within a rack ensures balance to each PDA and reduces
the possibility of an overload condition. Changing the cabling to or from a PDM could cause an
overload condition.
