A method and apparatus are provided for horizontally slicing a multi-stage switching fabric having transmission inputs and transmission outputs to and from the switch fabric. The switching fabric includes switch elements arranged in at least first and second stages, each switch element having element inputs and outputs with each switch element being configured to join one of the element inputs with an associated one of the element outputs. The switch fabric includes a first logic device that contains a stage-1subset of the switch elements that is arranged within, and configured to operate as part of, the first stage. The first logic device also contains a stage-2 subset of the switch elements arranged within, and configured to operate as part of, the second stage. The switch fabric includes a second logic device that contains a stage-1 subset of the switch elements that is arranged within, and configured to operate as part of, the first stage. The second logic device also contains a stage-2 subset of the switch elements that is arranged within, and configured to operate as part of, the second stage. The first and second logic devices are physically discrete from one another.
