Claim 19:
20. 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;
identifying, after the one of the data ports sends one of the load adjustment indications, that the one of the data ports and the one of the power supply ports are connected to the same one of the powered devices when an output power change manner of the one of the power supply ports matches a load adjustment manner indicated by the one of the load adjustment indications; and
performing the method within a duration of n time units, wherein the method further comprises identifying that the one of the data ports and the one of the power supply ports are connected to the same one of the powered devices when a binary sequence identified based on an output power of the one of the power supply ports is the same as a permutation and combination of one of the load adjustment manners indicated by the one of the load adjustment indications from the one of the data ports, wherein a jth-bit binary number in the binary sequence indicates an output power change status of the one of the power supply ports in a jth time unit in the n time units, wherein one binary number in the binary sequence indicates that an output power is unchanged, wherein the other binary number in the binary sequence indicates that the output power is changed, wherein the permutation and combination comprises a binary number 0 and a binary number 1, 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, and wherein the other binary number in the permutation and combination of the binary numbers indicates to adjust the load.
