A control circuit that provides a control signal to control, e.g., the hardware system of a server is disclosed. The control circuit operates based on the condition of the Baseboard Manageability Controller (BMC). Asserting the control signal turns on the hardware system, and the control circuit asserts the control signal when the control circuit has not received a heartbeat pulse from the BMC for more than a predetermined time. Further, the BMC is programmed to revoke generation of its heartbeat signal once it has completed initialization, and the BMC is programmed to deterministically generate a heartbeat within a predetermined time-period triggered on connection of AC power to the system.
