Abstract
The present invention provides for an Ethernet switch node providing power over Ethernet functionality for use in a power pooling system comprising at least one pooling controller, the Ethernet switch node providing power over Ethernet functionality comprising: a DC power source; an electrical load connected to the DC power source; a power sharing circuit responsive to an output of the at least one pooling controller, the power sharing circuit being operative to govern electrical power provided by the DC power source; and a DC electrical power connection to the DC power source and the electrical load, permitting external DC electrical power flow to and from the DC electrical power consuming and providing entity, wherein the Ethernet switch node providing power over Ethernet functionality has multiple modes, including a first operative mode in which the DC power source may provide more electrical power than is consumed by the electrical load.
