Abstract
Disclosed examples include redundant Power over Ethernet (PoE) systems, powered device (PD) controllers and methods in which a first PD controller sends a signal to indicate to the other PD controllers that the first PD controller is powered, and a second PD controller newly connected or reconnected to a corresponding power sourcing equipment (PSE) refrains from turning off a shared DC-DC converter, and the second PD controller waits to allow an inrush current delay of the corresponding PSE to complete before allowing current flow between the DC-DC converter and the corresponding PSE, and the second PD controller selectively provides a signal to request an application circuit powered by the DC-DC converter to temporarily reduce its power consumption below a predetermined value if the corresponding PSE is configured to provide no more than the predetermined value of power.
