A system includes multiple power sourcing equipment that can provide power to one or more powered devices via network connections. One or more of the power sourcing equipment with excess power capacity are determined. ## Claims ### Claim 1 A network management device comprising: a receiver to receive status information about a plurality of power sourcing equipment, each power sourcing equipment to provide power to a plurality of powered devices via respective network connections; an equipment manager module to determine a first power sourcing equipment, from among the plurality of power sourcing equipment, that is at or approaching its power sourcing capacity; a capacity identifier module to determine a second power sourcing equipment whose power sourcing capacity is below a threshold; and a redeployment module to select one or more of the powered devices to be redeployed from being powered by the first power sourcing equipment to being powered by the second power sourcing equipment based on criteria. ### Claim 2 (depends on 1) The network management device of claim 1, wherein the status information received from each respective power sourcing equipment includes a used power consumption level associated with the respective power sourcing equipment, and wherein the equipment manager module is to determine the first power sourcing equipment based on the used power consumption level meeting or exceeding a threshold power capacity. ### Claim 3 (depends on 2) The network management device of claim 2, wherein the equipment manager module maintains a count of how many times the used power consumption level meets or exceeds the threshold power capacity, wherein the equipment manager module determines the first power sourcing equipment based on a comparison of the count to a violation threshold. ### Claim 4 (depends on 1) The network management device of claim 1, wherein the capacity identifier module determines a set of the power sourcing equipment, based on the status information, with the excess power capacity, and wherein the set includes the second power sourcing equipment. ### Claim 5 (depends on 4) The network management device of claim 4, further comprising: a filtering module to filter the set based on respective spatial relationships between the first power sourcing equipment and the respective power sourcing equipment of the set, wherein the filtered set includes the second power sourcing equipment. ### Claim 6 (depends on 4) The network management device of claim 4, further comprising: a filtering module to filter the set based on a quantity of the excess power capacity of the respective power sourcing equipment, wherein the filtered set includes the second power sourcing equipment. ### Claim 7 (depends on 4) The network management device of claim 4, further comprising: a filtering module to filter the set based on a type of powered devices provided power by the respective power sourcing equipment, wherein the filtered set includes the second power sourcing equipment. ### Claim 8 A method comprising: receiving status information about a plurality of power sourcing equipment, each power sourcing equipment to provide power to a plurality of powered devices via respective network connections; determining that power usage of a first power sourcing equipment of the plurality of power sourcing equipment providing power to the plurality of powered devices via the network connection, is at or approaching its power sourcing capacity based on the status information; identifying a second power sourcing equipment with excess capacity to provide power; and selecting, based on criteria, one or more of the powered devices to be redeployed from the first power sourcing equipment to the second power sourcing equipment. ### Claim 9 (depends on 8) The method of claim 8, further comprising: receiving status information from the second power sourcing equipment, wherein the status information includes a power level available value and a consumed power level; and determining that the second power sourcing equipment has the excess capacity based on the power level available value and the consumed power level. ### Claim 10 (depends on 9) The method of claim 9, wherein the status information further includes a number of available network connection ports of the second power sourcing equipment, wherein the excess capacity is further based on the number of available network connection ports. ### Claim 11 (depends on 8) The method of claim 8, further comprising: determining a spatial relationship between the first power sourcing equipment and the second power sourcing equipment, wherein the identification is further based on the spatial relationship. ### Claim 12 A system comprising: a plurality of network elements; a plurality of network powered devices, wherein the network elements respectively provide power to a subset of the network powered devices via respective network connections; and a network management device comprising: a receiver to receive status information about the plurality of network elements; an equipment manager module to determine a network element, from among the plurality of network elements, that is at or approaching its power sourcing capacity based on the status information; a capacity identifier module to determine a list of the network elements with a power supply usage below a threshold level; and a redeployment module to select, based on criteria, one or more of the powered devices to be redeployed from being powered by a first power sourcing equipment to being powered by a second power sourcing equipment included in the list. ### Claim 13 (depends on 12) The system of claim 12, wherein the network management device further comprises: a filtering module to filter the list based on at least one of: spatial criteria, capability criteria, and utilization criteria. ### Claim 14 (depends on 12) The system of claim 12, further comprising: wherein the determination of the list is triggered based on a determination by the equipment manage module that a used power consumption level in one of the network elements is at or approaching its power sourcing capacity, and wherein the subset of the network powered devices associated with the one network element includes the other network powered device.
