Abstract
An information handling system includes first and second add-in cards and a riser printed circuit board (PCB). The first add-in card is configured to connect with a host system of the information handling system via a direct connection. The riser PCB includes first and second connectors. The first add-in card is in electrical communication with the riser PCB via the first connector. The second add-in card is in electrical communication with the riser PCB via the second connector. The first and second add-in cards are configured to communicate with each other via the first and second connectors and routing on the riser PCB.
Claims20
An information handling system comprising:
- first and second add-in cards, the first add-in card to connect with a host system of the information handling system via a direct connection;
- and
- a riser printed circuit board (PCB) including first and second connectors, the first add-in card in electrical communication with the riser PCB via the first connector, and the second add-in card in electrical communication with the riser PCB via the second connector, wherein the first and second add-in cards to communicate with each other via the first and second connectors and routing on the riser PCB, wherein the second add-in card to communicate with the host system via the first and second connectors, routing on the riser PCB, and the direct connection from a third connector on the first add-in card to the host system.
A method comprising:
- providing, via first and second connectors on a riser printed circuit board (PCB) of an information handling system, a first communication from a first add-in card of the information handling system to a second add-in card of the information handling system;
- providing, via a direct link from a third connector on the first add-in card, a second communication from the first add-in card to a host system of the information handling system;
- and
- providing, via the first and second connectors on the riser PCB and the direct link of the third connector on the first add-in card, a third communication from the second add-in card to the host system of the information handling system.
An information handling system comprising:
- a riser printed circuit board (PCB) including first and second connectors;
- a first add-in card including a third connector, the first add-in card in electrical communication with the riser PCB via the first connector, wherein the first add-in card is to connect with a host system of the information handling system via a direct connection through the third connector;
- and
- a second add-in card in electrical communication with the riser PCB via the second connector, wherein the first and second add-in cards to communicate with each other via the first and second connectors and routing on the riser PCB, wherein the second add-in card to communicate with the host system via the first and second connectors, routing on the riser PCB, and the third connector, wherein the first and second add-in cards are in a first configuration when the first and second connectors on mounted on a same surface of the riser PCB, wherein the first and second add-in cards are in a second configuration when the first and second connectors on mounted on opposite surfaces of the riser PCB.
