Abstract

The present invention provides a power management method, including: obtaining a trigger event from an extension power over Ethernet PoE system; determining that the trigger event causes an increase or decrease in a power load quota of the power management device; and if the power load amount is increased, providing the added power load amount to the switch with a higher priority; and, if the power load limit is reduced, supplying the power load supplied to the lower priority switch to the switch with higher priority. The invention also provides a power management device. The method and apparatus of the present invention can effectively perform power distribution for a desired machine and avoid overloading of the power management equipment.

Description

Technical field [0001] The present invention relates to a sub-communication technical field, in particular to a power management mechanism of a Power over Ethernet (PoE) switch (Switch) Background technique [0002] The Extension PoE System (EPS) is used to provide additional power to the Power Sourcing Equipment (PSE) switch, for example, the PoE switch, and can be based on its own power budget (Power Budget) Allocate the power load quota to the PoE switch or recycle the power load quota from the PoE switch. [0003] However, the existing EPS has the following disadvantages: [0004] (1) The EPS has multiple power supply units (Power Supply Unit, PSU), which can supply power to multiple PoE switches, and the power load quota 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 quota from the corresponding PSU cannot be reconfigured for use by other PoE switches; [0005] (2) The priority of the power supply ...
