Abstract
A power over ethernet (POE) power sourcing and distributing system that measures the power consumptions of a first and second power sourcing equipment (PSE) devices, transmits the second power consumption from the second PSE device to the first PSE device, calculates by the first PSE device a total power consumption from the first and second power consumptions, and compares by the first PSE device the total power consumption to a power consumption budget and disconnects a port of the first PSE device according to a first port disconnect list when the total power consumption is greater than a predetermined power consumption threshold.
Claims20
A method comprising:
- measuring by a first power sourcing equipment (PSE) device a first power consumption of the first PSE device;
- receiving a second power consumption from a second PSE device by the first PSE device;
- calculating by the first PSE device a total power consumption from the first and second power consumptions;
- and
- comparing by the first PSE device the total power consumption to a power consumption budget and disconnecting a port of the first PSE device according to a first port disconnect list when the total power consumption is greater than a predetermined power consumption threshold.
A system comprising:
- a first power sourcing equipment (PSE) device having a first PSE device circuit to measure a first power consumption of the first PSE device and a first PSE device receiver to receive a second power consumption from a second PSE device;
- wherein the first PSE device circuit is to:
- calculate a total power consumption from the first and second power consumptions;
- compare the total power consumption to a predetermined power consumption threshold;
- and
- disconnect a port of the first PSE device according to a first port disconnect list when the total power consumption is greater than the predetermined power consumption threshold.
A system comprising:
- a first power sourcing equipment (PSE) device;
- a second PSE device;
- a device bus connecting the first and second PSE devices to transmit with a period less than twenty milliseconds;
- a power over ethernet (POE) host;
- and
- a management bus connecting the POE host to the first and second PSE devices to transmit with a period greater than one second.
