An interconnection network comprises a pair of backplanes for receiving X pluggable node cards. The pair of backplanes include X backplane connector groups, each backplane connector group adapted to receive mating connectors from a pluggable node card. Each backplane connector group includes X/2 connectors. A first backplane includes first permanent wiring which interconnects a first subset of pairs of connectors between backplane connector groups. A second backplane includes second permanent wiring which interconnects a second subset of pairs of connectors between backplane connector groups. The first permanent wiring and second permanent wiring connect complementary subsets' of pairs of the connectors. A plurality of node cards, each including a card connector group, pluggably mate with the backplane connector groups. Each node card further includes a frontal connector that is adapted to receive a cable interconnection. Each node card includes a processor and a switch module which simultaneously connects the processor to at least plural connectors of a backplane connector group.
