Abstract
A central system coupled to a subsystem receives a fault indication associated with a fault in one or more circuits of the subsystem from a local fault collection and control (FCCS) of the subsystem when a software recovery of the fault fails. Based on the received fault indication, the local FCCS and a central FCCS of a central system is masked from additional fault indications from the one or more circuits. The central system then signals the reset of the one or more circuits of the subsystem after the masking of the additional fault indications, wherein the one or more circuits is reset based on the signaling and the additional faults are masked from one or more of the local FCCS and central FCCS during the reset.
