A printed circuit board (PCB) for an Advanced Telecommunications Computing Architecture (ATCA) shelf. The ATCA shelf may include a backplane providing a payload power supply and a standby power supply. Additionally, the PCB may include a first shelf management controller (ShMC) and a multiport switch, the multiport switch electrically coupling the first ShMC with a second ShMC on a second PCB by way of the backplane, the first ShMC utilizing standby power provided by the backplane at least when payload power is not available. |
