Power over ethernet switch node for use in power pooling
First Claim
1. 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 said DC power source;
a power sharing circuit responsive to an output of the at least one pooling controller, said power sharing circuit being operative to govern electrical power provided by said DC power source; and
a DC electrical power connection to said DC power source and said 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 at least a first operative mode in which said DC power source may provide more electrical power than is consumed by said electrical load and a second operative mode in which said electrical load may consume more electrical power than is provided by said DC power source.

11. A method of DC power pooling for an Ethernet switch node having power over Ethernet functionality in a power pooling system comprising at least one pooling controller, the method comprising:
-
providing a DC power source;
providing an electrical load associated with said DC power source;
connecting said DC power source to said electrical load;
governing the electrical power provided by said DC power source; and
providing a DC electrical power connection to said DC power source and said electrical load, thereby permitting external DC electrical power flow to and from the DC electrical power consuming and providing entity, wherein the Ethernet switch node having power over Ethernet functionality has at least a first operative mode in which it may provide more electrical power than it consumes and a second operative mode in which it may consume more electrical power than it provides. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
