The document discusses an OCP 48V solution presented at a 2019 Tokyo meetup. It references expansion boards, rackspace, and Google and Rackspace's P9 48V OCP design for powering servers more efficiently using a 48V standard. Component specifications are provided for PSUC1, C2 and PSUCE1, CE2 capacitors. A GitHub link is also included for the Zaius-Barreleye-G2 design.
