Abstract: A method for migrating a power shelf between being supplied single-phase power and three-phase power includes coupling a second power adapter to an input of a power shelf of a rack while power is being supplied to the power shelf via a first power adapter coupled to another input of the power shelf. The first power adapter includes a multi-pin connector coupled to the input and three other connectors each coupled to respective single-phase power sources and the second power adapter includes a multi-pin connector configured to couple with the other input and another connector configured to couple with a three-phase power source.
