Methods, systems, and apparatus for configuring a network device are disclosed. In one aspect, a network address that is assigned to the network device by a network address server is detected by an equipment configuration device. The network address server differs from the network device. In response to detecting the network address, a set of connection parameters that connect the network device to a controller device is transmitted by the equipment configuration device and to the network device. The set of connection parameters is transmitted outside of communications, transmitted by the network address server, that assigned the network address to the network device.
