Owners Manual

CAUTION: Do not plug the enclosure into a standard power outlet. Your storage array is shipped with two IEC
C19 to C20 jumper cables. Connect the C19 plug to the array’s power supplies and the C20 plug to the power
distribution unit (PDU) in the rack cabinet. For power redundancy, split the power connections from each
enclosure into separate PDUs and connect the PDUs to external power receptacles on different circuits. The
enclosure supports only 200 V to 240 V input sources.
