Abstract
A field replaceable unit authentication system provides for a field replaceable unit device to be positioned in a chassis. A trusted platform module is included in the field replaceable unit device. A network operating system engine may be provided in the field replaceable unit device and coupled to the trusted platform module. The network operating system engine participates in a boot process with a booting subsystem to generate current boot metric data that is provided for storage in the trusted platform module. A platform management controller in the field replaceable unit device retrieves the current boot metric data from the trusted platform module, authenticates the trusted platform module, and compares the current boot metric data to previously stored boot metric data to determine whether to authenticate the network operating system engine. If authenticated, the network operating system engine then authenticates the platform management controller.
