Power cycle circuit

A circuit card comprising:

• one or more devices,
• a controller for controlling operation of the circuit card,
• a switch responsive to a command received from the controller, for causing electrical power to at least one device to be decoupled therefrom for a predetermined period of time, and
• an electrical power device, operable independent of the controller, that causes electrical power to the at least one device and the controller to be restored after the predetermined time period if the electrical power was also decoupled from the controller.

A circuit card comprising:

• a device for performing operations associated with the circuit card,
• a switch for switchably coupling electrical power to the device to enable the device to operate,
• the device including a module for controlling the switch to decouple electrical power from the device, and
• the circuit card further comprises a switch controller, operable independent of the device, for controlling the switch to restore electrical power to the device a predetermined time after the switch decouples electrical power from the device if the switch decoupled electrical power from the device.
