Abstract
Maintenance of reliable and highly available electronic systems to perform servicing and preventive maintenance may need to be performed without interruption of operations. Removal of circuit cards from a chassis may render the connectors on a chassis vulnerable to inadvertent short circuiting of power sources by stray metallic objects. A configuration where the power is removed from a connector as the circuit card is being extracted eliminates his possibility. The control circuits for the power supply connections and the power supplies are themselves redundant so that they may be similarly serviced.
