The HPE P48077-001 is a 350W non-hot-plug power supply for HPE ML30 server configurations. It powers a compatible server, but is not designed for replacement while the system is running.
HPE lists it for ML30 Gen10 Plus and ML30 Gen11 configurations. Its non-hot-plug design is relevant when planning server maintenance: the system must not be running during replacement. It can serve as a replacement power unit for a supported HPE ML30 server.
