A device management system includes an accommodation apparatus, a network device, and a device management apparatus. The accommodation apparatus includes a plurality of storage spaces. Each of the plurality of storage spaces is capable of storing an electronic device. The network device is connected to an electronic device accommodated in the accommodation apparatus. The device management apparatus includes a processor. The processor obtains connection information when a first electronic device is newly placed in the accommodation apparatus. The connection information indicates an expected connection point in the network device. The first electronic device is to be connected to the network device at the expected connection point with a cable. The processor identifies an actual connection point at which the network device has been connected to the first electronic device with the cable. The processor determines, based on the connection information, whether the actual connection point is appropriate.
