Abstract

A method for managing a power supply comprises an Extension Power over Ethernet System receiving a trigger event. A determination is made as to whether the trigger event would cause a power budget of a power supply management device to increase or decrease; if the power is increased, the power is provided to a switch with a higher priority; if the power is decreased, power can be provided to a switch with a higher priority from a lower priority. A device for power supply management is also disclosed, the method and the device can effectively allocate power as required and avoid equipment overload.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a power management mechanism of a Power over Ethernet (PoE) switch (Switch) Background technique [0002] Extended Power over Ethernet system (Extension PoE System, EPS) is used to provide additional power to power supply equipment (Power Sourcing Equipment, PSE) switches, such as PoE switches, and can be based on its own power load (Power Budget) Allocate (Allocate) the power load quota to the PoE switch or recycle (Recycle) the power load quota from the PoE switch. [0003] However, existing EPS has the following disadvantages: [0004] (1) The EPS has a plurality of power supply units (Power Supply Unit, PSU), which can supply power to multiple PoE switches, and the power load of each PSU is fixed. When one of the PoE switches no longer needs to be powered by the corresponding PSU, the extra power load of the corresponding PSU cannot be reconfigured for use by ...
