Patent attributes
One or more stacking cabled I/O slots may be installed in a stacked arrangement on a computing device, such as in an I/O expansion socket of a computing device motherboard. Slot detection and population logic associated with each of the one or more stacking cabled I/O slots enables signaling from each installed stacking cabled I/O slot, in order for its presence and location relative to any other installed stacking cabled I/O slot to be identified to and recognized by the computing device. High speed data signals through an installed stacking cabled I/O slot are coupled to the computing device via a cable, while power and logic signals are exchanged between the computing device and the one or more stacking cabled I/O slots via connections to the I/O expansion socket.
