Riser card for a vertical mounting of an expansion card

Abstract

A riser card includes a circuit board and first, second, and third connectors. The first and second connectors are positioned at bottom and top edges of the circuit board, respectively. The third connector is mounted to a face of the circuit board. Such riser card may be mounted on a primary system board such that the first connector is detachably connected to a first complementary connector of the primary system board with the circuit board perpendicular to the primary system board, and the first connector receives power, data, and sideband signals from the first complementary connector. The second and third connectors may mate with second and third complementary connectors of an expansion card oriented parallel to the circuit board and a stackable secondary riser card oriented perpendicular to the circuit board, respectively. The riser card communicates power and sideband signals to the stackable secondary riser card via the third connector.
