Abstract
A physical interconnection architecture for making connections between a plurality of first printed-circuit boards and a plurality of second printed-circuit boards includes a midplane printed-circuit board having a plurality of first connectors oriented in a first direction on one side of the midplane for making connections to the plurality of first printed-circuit boards. The midplane printed-circuit board also has a plurality of second connectors oriented in a second direction orthogonal to the plurality of first connectors on the other side of the midplane. The connectors are positioned such that connection pins on the plurality of first connectors and plurality of second connectors in regions of intersection are double-ended pins common to both. The remaining connection pins of the plurality of first connectors are single-ended connection pins which are connected to the single-ended connection pins of the plurality of second connectors via conductive traces on the midplane printed-circuit board.
