| 1. A circuit card comprising:
a device;
a controller for controlling operation of the device, and
a switch for switchably coupling electrical power to the device to enable the device to operate,
the controller including a module for controlling the switch to decouple the electrical power from the device,
and the circuit card further comprising a switch controller, operable independent of the controller, for controlling the switch,
if the switch also decouples electrical power from the controller, to restore the electrical power to the device and the controller
a predetermined time after the switch decouples the electrical power from the device and the controller.
