Abstract: According to one embodiment of the invention, a method for providing redundancy for a card in a chassis includes providing first and second cards in a chassis. Each card has an output node connected to a common bus and a respective input node. The method also includes providing a facilitator card in the chassis. The facilitator card includes an input node connected to the common bus and an output node connected to the input node. The method further includes connecting the input node of the second card to the output node of the facilitator card and connecting the input node of the first card to the associated output node of the first card. This couples the input node of the first card to the input node of the second card to provide redundancy for the first card.
