ABSTRACT:
A Power-over-Ethernet (PoE) communication system dynamically provides power and data communications over a communications link. In an enterprise environment made up of one or more personal computing devices (e.g., personal or laptop computers), a switch determines an allocated amount of power to be supplied to each device. The system includes a switch, a power supply, and one or more personal computing devices having a PoE control module. The PoE control module can be part of, for example, a Power Source Equipment/Powered Device (PSE/PD) system or a LAN-On-Motherboard/Powered Device (LOM/PD) system. A method of dynamically providing power to personal computing devices includes determining the power requirements of each device based on one or more factors, which can include, for example, battery charge status, power load, power mode, etc., of each device. Various algorithms can be used to decide priority in providing power to the devices.
