1. A power consumption grading method for a network-based power supply system, wherein the network-based power supply system comprises power sourcing equipment and a powered device, the power sourcing equipment supplies power to the powered device over a network, and the method comprises:
in response to detecting, by the powered device, that power overload protection for the power sourcing equipment is not triggered, starting, by the powered device, a plurality of power modules of the powered device one by one in a specific order until either all the plurality of power modules are started or the powered device detects that the power overload protection for the power sourcing equipment is triggered after a specific power module of the plurality of power modules is started, wherein the powered device detects, based on a voltage signal and a current signal that are received from the network, whether the power overload protection for the power sourcing equipment is triggered;
in response to detecting, by the powered device, that the power overload protection for the power sourcing equipment is triggered, selecting, by the network-based power supply system according to the specific order and based on the specific power module, one or more of the plurality of power modules as a power module combination of the powered device;
and
determining, by the network-based power supply system, a load power of the powered device and a corresponding power consumption level based on the power module combination.
