Abstract
A compute node includes a motherboard having a trusted platform module, and also includes a port for selectively coupling a hot pluggable device into communication with the motherboard. The compute node further includes a circuit coupled to the port for detecting a change in the physical connection of the hot pluggable device to the port and for asserting a physical presence signal to the trusted platform module in response to detecting a change in the physical connection of the hot pluggable device to the port. The change in the physical connection of the hot pluggable device to the port may include either physically connecting the hot pluggable device to the port, physically disconnecting the hot pluggable device from the port, or a combination thereof.
