Abstract
A method, system and computer program product are provided for implementing sideband control structure for Peripheral Component Interconnect Express (PCIE) add-in cards, or cable cards, that utilize cables to connect to input/output (IO) expansion enclosures in a computer system. System firmware uniquely identifies a cable card present in a PCIE slot in a system unit. Enclosure management functions utilize sideband control paths integrated within at least cable providing sideband control signaling, and providing PCIE signaling lanes between the cable card and the IO enclosure.
