Power Supplies
Your system supports two
When two identical power supplies are installed, the power supply configuration is redundant. In redundant mode, power is supplied to the system equally from both power supplies to maximize efficiency.
When one power supply module is removed or has failed, the power supply configuration is non- redundant. Power is supplied to the system only by the single power supply module.
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.
