ABSTRACT:
A memory metal hot plug connector apparatus and method which provide a physical lock that prevents removal of a circuit card from a system board until power and system functional signals have been electrically disconnected. The memory metal in the connector releases the physical lock when heated. A power supply interface controller issues commands to connect and disconnect power to the circuit card and to heaters associated with the memory metal connectors. A test signal circuit provides JTAG standard signals for connecting and disconnecting system functional signals. Methods for connecting and disconnecting the circuit card are also disclosed.
