Abstract:
A hot swappable processor card for a hot swap bus, the hot swappable processor card plugging into a processor slot of the hot swap bus, the hot swappable processor card comprising:a connector for plugging into the processor slot, the hot swappable processor card being hot swapped into the hot swap bus by plugging the connector into the processor slot, and hot swapped out of the hot swap bus by unplugging the connector from the processor slot; signal switching circuitry for connecting signal lines on the hot swappable processor card to signal lines of the hot swap bus, the signal switching circuitry electrically connected to the connector and enabling the hot swappable processor card to be hot swapped; a processor electrically connected to the signal switching circuitry; power switching circuitry for controlling power to the processor card; and a communications line for communicating with a second processor card that is plugged into the hot swap bus; wherein the second processor card can control the signal switching circuitry to electrically disconnect the hot swappable processor card from the bus.
