    摘要： Methods and systems for managing power for a Power over Ethernet (PoE) device are disclosed herein. The method may include obtaining, by a supervisor, power information from a plurality of power supply units (PSUs) to obtain total consumed power; obtaining, by the supervisor, a total system power capacity value associated with the plurality of PSUs; and calculating, by the supervisor, a total available PoE power value using the total consumed power and the total system power capacity value; and making a first determination, by the supervisor, using the total available PoE power value and a PoE power table, whether a powered device should stop receiving power.

    摘要： Methods and systems for managing power for a Power over Ethernet (PoE) device are disclosed herein. The method may include: configuring a power sourcing equipment (PSE) controller component with an interface keep-on order that indicates a relative priority for providing power to interfaces of the PSE controller component; storing, by a supervisor, keep-on order values and interface identifiers in entries of a PoE power table; transmitting to the supervisor, by the PSE controller component, a first interface power draw value associated with a first interface and a second interface power draw value associated with a second interface; storing, by the supervisor, the interface power draw values entries associated with the respective interfaces; and performing, by the supervisor and in response to a power event, a power management action.
