ABSTRACT:
A backplane having a switch card interface and an adapter card interface where the switch card interface has input/outputs in an arrangement that functionally mate to a networking layer system switch card and a physical layer system switch card. The adapter card interface is coupled to the switch card interface. The adapter card interface has input/outputs in an arrangement that functionally mates to a networking layer system adapter card and a physical layer system adapter card. A method that involves forming a first and second backplane according to a manufacturing process, integrating the first backplane into a networking layer system switch, and integrating the second backplane into a physical layer system switch.
