Power specification
s
The input voltage to the drive enclosure power supplies is a function of the country-specificinputvoltage
to Enterprise storage system rack power distribution units (PDUs) . Table 34 defines the AC input power
available to the dr
ive enclosure power supplies.
CAUTION:
The AC power distribution within a rack ensures a balanced to each PDA and reduces the possibilit y of
an overload condition. Changing the cabling to or from a PDM could cause an overload condition.
