Abstract
A system includes an electronic device including a baseboard management controller (BMC), a power supply unit (PSU), and an external connector, wherein the BMC controls a serial communication bus, and the external connector includes AC voltage contacts and serial communication bus contacts. A power distribution unit (PDU) includes multiple outlets, a management entity, a radio frequency identification (RFID) tag reader, and a visual indicator. A power cable includes a first plug end for coupling to the external connector, a second plug end for coupling to one of the outlets, AC voltage wires extending end-to-end, a read/write RFID tag in the second plug end, and communication wires extending from the first plug end to the read/write RFID tag. Coupling the first plug end to the external connector connects the AC voltage and connects the serial communication bus such that the BMC is in serial communication with the read/write RFID tag.
