US 2021/0278889 A1 · POWERING METHOD AND POWERING SYSTEM FOR POWER OVER ETHERNET

Abstract

The present invention provides a power supply system and power supply method thereof for Power over Ethernet. The power supply system is configured to: calculate a static allocation remaining power and a dynamic allocation remaining power of power sourcing equipment; and determine whether a consuming power of powered device is greater than the static allocation remaining power and the dynamic allocation remaining power. When the consuming power is less than or equal to the static allocation remaining power and is less than or equal to the dynamic allocation remaining power, the powering system is configured to perform a static powering procedure. When the consuming power is greater than the static allocation remaining power and is less than or equal to the dynamic allocation remaining power, the powering system is configured to perform a dynamic powering procedure.

Dependent claims

A power supply method for use in Power over Ethernet (POE), comprising:

calculating a static allocation remaining power and a dynamic allocation remaining power of a power sourcing equipment (PSE);
and
determining whether a first consuming power of a first powered device (PD) of at least one PD is greater than the static allocation remaining power and the dynamic allocation remaining power, wherein:
performing a static power supply procedure when the first consuming power is less than or equal to the static allocation remaining power and the first consuming power is less than or equal to the dynamic allocation remaining power;
and
performing a dynamic power supply procedure when the first consuming power is greater than the static allocation remaining power and the first consuming power is less than or equal to the dynamic allocation remaining power.
