Dynamically Configurable Power-Over-Ethernet Apparatus and Method |
摘要 |
One or more dual-role Power-over-Ethernet (PoE) port units are each selectively configurable to operate as either (i) a PoE Power Source Equipment (PSE) port unit to provide power to a device connected to the PoE port unit, or (ii) a PoE Powered Device (PD) port unit to sink power from the connected device. Each PoE port unit includes a network port, and a bi-directional power converter to selectively convert power in either (i) a first direction and to provide converted power to the network port when the PoE port unit operates as the PSE port unit, or (ii) in a second direction to convert power received from the network port when the PoE port unit operates as the PD port unit. |

1. An apparatus comprising:
one or more dual-role Power-over-Ethernet (PoE) port units, each PoE port unit being selectively configurable to operate as either (i) a PoE Power Source Equipment (PSE) port unit to provide power to a device connected to the PoE port unit, or (ii) a PoE Powered Device (PD) port unit to sink power from the connected device, wherein each PoE port unit includes: a port to mate with a network cable; and a bi-directional power converter to selectively convert power in either a first direction and to provide converted power to the port when the PoE port unit is configured to operate as the PSE port unit, or in a second direction to convert power received from the port when the PoE port unit is configured to operate as the PD port unit. |
