Embodiments of the present disclosure provide a method and apparatus for determining a physical position of a device. The method comprises: transmitting a control command to the device, the command instructing the device to change power loading of the device in a predetermined pattern; receiving, from a power distribution unit providing power supply for the device, a network address of the power distribution unit, the network address being transmitted by the power distribution unit in response to detecting the change of the power loading in the predetermined pattern; and determining the physical position of the device based at least on the network address of the power distribution unit. With the technical solution according to the embodiments of the present disclosure, the position of the device can be automatically determined without any manual intervention, which helps to control the operation cost and improve the maintenance efficiency.
