Abstract
A connection manner identification method includes power sourcing equipment separately sending load adjustment indications to powered devices by using data ports, where each load adjustment indication in the load adjustment indications indicates a corresponding powered device to adjust a load. The powered devices are separately connected to power supply ports of the power sourcing equipment by using power supply cables, and the powered devices are separately connected to the data ports of the power sourcing equipment by using data cables. The power sourcing equipment obtains output power changes of the power supply ports caused by load adjustment of the powered devices, and the power sourcing equipment determines, based on the output power changes, a first data port and a power supply port that are connected to a same powered device in the powered devices.
