A backplane in a power distribution shelf has power outputs connected to corresponding primary card slots and adjacent card slots. Power distribution cards are seated in the card slots. A maintenance card can be configured to selectively provide redundant power to the power outputs of a failed power distribution circuit card via an adjacent power distribution circuit card and a maintenance connection.
