The motherboard includes one or two CMP modules, memory control subsystems, and all SP (Oracle ILOM) logic. The motherboard hosts a removable SCC module, which contains all MAC addresses, host ID, and Oracle ILOM configuration data. The motherboard connects directly to the PS backplane, which distributes main 12V power from the power supplies to the rest of the server. The PS backplane is directly connected to the motherboard through a bus bar and ribbon cable and supports a top cover safety interlock switch.
