Claim 18:
19. A method implemented by power sourcing equipment, the method comprising:
separately sending a plurality of load adjustment indications to a plurality of powered devices by using a plurality of data ports, wherein the load adjustment indications comprise a plurality of load adjustment manners, wherein the load adjustment manners are different from each other, wherein each load adjustment indication instructs one of the powered devices to perform a load adjustment, wherein a plurality of power supply ports of the power sourcing equipment are configured to connect to the powered devices by using a plurality of power supply cables, and wherein the data ports are configured to connect to the powered devices by using a plurality of data cables;
obtaining output power changes of power supply ports caused by load adjustment of the powered devices;
identifying, based on the output power changes, one of the data ports and one of the power supply ports that are connected to a same one of the powered devices; and
performing the method within a duration of n time units, wherein M load adjustment indications instruct to perform load adjustment based on load adjustment manners indicated by M permutations and combinations in 2n permutations and combinations of n bits of binary numbers, wherein an ith-bit binary number in the permutation and combination indicates a load adjustment status in an ith time unit in the n time units, wherein one binary number in the permutation and combination indicates to not adjust a load, wherein the other binary number in the permutation and combination indicates to adjust the load, and wherein M is less than or equal to 2n.
