A system interface having a backplane adapted to have plugged therein director boards and memory boards. Each one of such director boards includes director board transmit/receive units. Each one of the director board transmit/receive units is associated with a corresponding one of the of memory boards. Each one of the director board transmit/receive units is adapted to be disabled in the absence of the one of the memory boards associated with such one of the director board transmit/receive units. Each one of the memory boards includes memory board transmit/receive units. Each one of the memory board transmit/receive units is associated with a corresponding one of the director boards. Each one of the memory board transmit/receive units is adapted to be disabled to prevent transmit/receive data therethrough in the absence of the one of such director boards associated with such one of the memory board transmit/receive units.
