An adapter and method for coupling an inline powered communications device to a primary network and to a secondary network, the communications device configured for having an assigned device identification and configurable for using an assigned network address for use in routing data over at least one of the networks. The adapter and method comprise a first port for connecting to the communications device to facilitate the communication of the data and inline power between the adapter and the communications device, the inline power for use in operating the communications device. The adapter and method comprise a second port for connecting to the primary network to facilitate the communication of the data between the primary network and the communications device via the first port, the second port coupled to the first port, and a third port for connecting to the secondary network to facilitate the supply of the inline power between the secondary network and the communications device via the first port, the second port coupled to the first port. The adapter and method also comprise a power coupling module configured for providing a transmission path of the inline power between the first port and the third port when the inline power is unavailable from primary network via the second port. |
