Removing A Power Supply Module - Dell PowerVault MD3060e Owner's Manual

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 a single power supply module.
CAUTION: Do not plug the enclosure into a standard power outlet. Your storage enclosure is
shipped with two IEC C19 to C20 jumper cables. Connect the C19 plug to the enclosure'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.
