Abstract
Methods, systems, apparatus, and computer-readable media for providing a redundant power solution for an expansion card installed within a host computer. The expansion card has a hardware device and a power control mechanism. The power control mechanism provides power to the hardware device from a conditional power source when available, and from computer system standby power when the conditional power source is unavailable. The power control mechanism may comprise a power sensing mechanism to determine when conditional power source output decreases below a threshold level and a switching mechanism to switch from the conditional power source to computer system standby power when this happens. The hardware device may enter a low power mode upon receiving computer system standby power.
