Abstract

In some examples, a Powered Device (PD) having dual Power over Ethernet (PoE) redundancy comprises a first PD chip to interact with a first PoE port comprised in a first Power Sourcing Equipment (PSE), a second PD chip to interact with a second PoE port comprised in a second PSE, a first control logic module to permit the first PD chip to independently interact with the first PoE port, a second control logic module to permit the second PD chip to independently interact with the second PoE port, a first Field Effect Transistor FET to turn on/off a first diode, the first FET being controlled by the first control logic module, a second FET to turn on/off a second diode, the second FET being controlled by the second control logic module. The first and the second diodes to combine the first and the second voltages from the first and the second PSE, respectively. Furthermore, the PD comprises a first bridge diode to draw a first voltage from the first PSE upon permitted interaction by the first control logic module, a second bridge diode to draw a second voltage from the second PSE upon permitted interaction by the second control logic module and a voltage converter to input the combined voltage level from the first and the second diodes and output a lower voltage level.
