ABSTRACT:
One embodiment of the present invention provides an apparatus for removing signals and power from a bus card in a computer system when the bus card is inadvertently removed from the computer system while the computer system is operating. This apparatus includes a bus connector, for receiving a bus card, and a power conductor to provide an electrical coupling between the bus card and a power source. The apparatus also includes a power switch coupled between the power conductor and the bus connector, to selectively provide power to a bus card in the bus connector. The apparatus additionally includes a movement sensor, for sensing a movement of the bus card from the bus connector. The apparatus also includes a controller coupled between the movement sensor and the power switch, for activating the power switch to remove power from the bus card when the movement sensor detects a movement of the bus card from the bus connector. The present invention can thereby prevent damage or failure of the computer system when a bus card is inadvertently removed from the computer system by powering down the bus card and/or removing signals from the bus card before it is completely removed.
