A rack switch coupling system includes computing devices positioned in a rack in a stacked orientation. A switch system positioned in the rack includes a circuit board with a processing system. Respective first ports are each located on the circuit board, coupled to the processing system via a respective trace on the circuit board, cabled to a respective one of the computing devices, and located adjacent its cabled computing device between a top plane and a bottom plane associated with that computing device. Respective second ports are each located off of the circuit board, coupled to the processing system via a respective trace on the circuit board and a respective cable extending between that trace and that second port, cabled to a respective one of the computing devices, and located adjacent its cabled computing device between a top plane and a bottom plane associated with that computing device.
