Abstract:
1. A method, comprising: using a firmware interface setup program for a selected compute node to cause a firmware interface on the selected compute node to enable a trusted platform module on the selected compute node to be able to receive a physical presence signal, wherein the selected compute node is selected from a plurality of compute nodes within a multi-node chassis, and wherein each of the plurality of compute nodes includes a firmware interface and a trusted platform module; manually actuating a device within the multi-node chassis to transmit a physical presence signal to each of the plurality of compute nodes within the multi-node chassis; each of the plurality of compute nodes within the multi-node chassis receiving the physical presence signal; asserting the physical presence signal to the trusted platform module of the selected compute node in response to both enabling the trusted platform module of the selected compute node to be able to receive the physical presence signal and receiving the physical presence signal; and allowing modification of one or more security setting of the selected compute node in response to the trusted platform module of the selected compute node receiving the physical presence signal.
