Abstract
Active and spare circuit cards are each paired with switch cards. Each switch on the switch cards is daisy chained with prior and succeeding switches. A master controller senses a faulty circuit indication signal from each of the active circuit cards. When the faulty circuit indication signal indicates a fault on a particular active circuit card, the controller instructs the switch card that is paired with that circuit card to switch it out and switch in a spare circuit card.
