More Information
Summary:A Power Distribution Unit (PDU) control system controls a PDU and communicates with a server management controller of a server. Through its connections, the PDU control system can track and manage the power supplies and locations of servers connected to those power supplies. A PDU receives commands at its communications port from a PDU control system to shut down a power strip or power outlet to which the PDU is connected via one of plural power interfaces. In turn, a server's management controller detects when a power supply shuts down due to the shut down of the power strip or power outlet. The server's management controller can be either queried by the PDU control system or the controller can send a notification to the PDU control system indicating which power supply lost power, thereby correlating the power strip to the server.
