Method for removing power and signals from an inadvertently swapped bus card

A method for removing connections to a bus card in a computer system when the bus card is inadvertently removed from the computer system while the computer system is operating, comprising:

• sensing a movement of the bus card from a bus connector in the computer system while the computer system is operating;
• in response to the movement, waiting until a bus transaction involving the bus card completes;
• saving a state from the bus card to the computer system;
• removing power from the bus card;
• sensing an insertion of a new bus card into the bus connector;
• in response to the insertion of the new bus card, resetting the new bus card to an initial state;
• and
• restoring the state to the new bus card from the computer system.

A method for removing connections to a bus card in a computer system when the bus card is inadvertently removed from the computer system while the computer system is operating, comprising:

• sensing a movement of the bus card from a bus connector in the computer system using two switches located at opposing ends of the bus connector while the computer system is operating;
• in response to the movement, waiting until a bus transaction involving the bus card completes;
• saving a state from the bus card to the computer system;
• removing power from the bus card;
• sensing an insertion of a new bus card into the bus connector;
• in response to the insertion of the new bus card, resetting the new bus card by reinitializing the new bus card to an initial state;
• and
• restoring the state to the new bus card from the computer system.
