Abstract
Active cables and communication methods can provide data path redundancy with power sharing. In one illustrative cable implementation, the cable includes a first connector with contacts to supply power to circuitry in the first connector; a second connector with contacts to supply power to a component of the circuitry in the first connector via a first connection that prevents reverse current flow; and a third connector with contacts to supply power to the same component via a second connection that prevents reverse current flow. An illustrative method implementation includes: using contacts of a first connector to supply power to circuitry in the first connector; and using contacts in each of multiple redundant connectors to supply power to a component of said circuitry in the first connector via a corresponding diodic or switched connection that prevents reverse current flow.
