Abstract: An information handling system may include a host system comprising a host system processor, a logic device configured to perform a functionality of the information handling system in accordance with code stored on non-transitory computer-readable media of the logic device, and a management controller communicatively coupled to the host system processor and the logic device and configured to perform out-of-band management of the information handling system. The management controller may be further configured to: during a boot of the management controller, perform an initial authentication of the code via an immutable interface of the logic device, after the initial authentication and prior to completion of boot of the management controller, enable a hardware lock to prevent write access to the logic device via the immutable interface, and in response to a power on request of the host system, perform a second authentication of the code via a mutable interface of the logic device.

Abstract: A communication module may be used in an information handling system comprising an air mover configured to drive a flow of air and a processing component communicatively coupled to the air mover for controlling operation of the air mover via a first wire configured to communicate air mover speed commands from the processing component to the air mover for controlling a speed of the air mover and a second wire configured to communicate tachometer information from the air mover to the processing component. The communication module may include a connector other than an air mover connector configured to couple the air mover to the first wire and the second wire and logic configured to monitor for an escape sequence communicated over the first wire from the processing component to enter a command mode and responsive to detecting the escape sequence, communicating information regarding the air mover to the processing component via the second wire.

Abstract: An information handling system comprising may include a host system processor and a management controller communicatively coupled to the host system processor and configured to perform out-of-band management of the information handling system. The management controller may be further configured to, during boot of the information handling system read a known configuration for the information handling system from a storage resource accessible to the management controller, determine a current configuration of the information handling system, compare the known configuration to the current configuration, and in response to a mismatch between the known configuration and the current configuration, report an indication of the mismatch to a user of the information handling system and receive a desired user action for responding to the mismatch.

Abstract: In accordance with embodiments of the present disclosure, a method may include, during boot of a modular information handling system disposed in a chassis configured to receive a plurality of modular information handling systems and a plurality of modular information handling resources, pausing execution of a basic input/output system. The method may also include communicating a first indicator, wherein the first indicator causes a chassis management controller of the chassis to perform link optimization operations of a communication link between the modular information handling system and a modular information handling resource. The method may further include, in response to communication by the chassis management controller of a second indicator, the second indicator indicating completion of link optimization operations by the chassis management controller, unpausing execution of the basic input/output system.
