Abstract: An example redundant power supply system comprises a power supply input to receive power from a power supply; a buck-boost converter coupled to the power supply input; and a controller coupled to the buck-boost converter. The controller is to receive a power supply identification signal from the power supply. The controller is also to enable or disable the buck-boost converter based on the power supply identification signal.

Abstract: In example implementations, an apparatus is provided. The apparatus includes a polymer based enclosure, an absorber, and a connection interface. The polymer based enclosure is shaped to enclose a memory module connected to a memory module connection interface on a printed circuit board. The absorber is coated over the polymer based enclosure to block radio frequency signals generated by the memory modules. The connection interface is to connect to the memory module connection interface.
