Abstract
A system to monitor power loading in a plurality of power distribution units. The system includes a power monitoring gateway with a port configured to communicate with an internet protocol network using an internet protocol address. The power monitoring gateway is also configured to communicate with the plurality of power distribution units through a communication link that does not use internet protocol addressing. The communication link in some embodiments is a wireless link. In other embodiments, the communication link uses a single pair of wires with the power monitoring gateway and the power distribution units configured in a daisy chain topology.
