Patent ID: 8880915

Claim:
A system, comprising: power sourcing equipment configured for providing power to a powered device via a channel; and a sub-system configured for: determining, based on a resistance of the channel, an amount by which to increase a level of power provided to the powered device by: selecting a base load in the powered device to receive power, determining respective priorities for a plurality of optional loads in the powered device, determining a respective power requirement of each of the plurality of optional loads in the powered device, and selecting one or more optional loads selected to receive power in order of priority until a power requirement of an additional optional load would cause the level of power provided to the powered device to exceed a maximum level of power based on the resistance of the channel; wherein the power sourcing equipment is configured to adjust the level of power by the amount in response to a command from the sub-system, wherein the amount is equal to a sum of the respective power requirements of the base load and the one or more optional loads selected to receive power.
