Method and apparatus for receiving power over a data network

摘要

A method, apparatus, and computer usable program product for receiving power over Ethernet in a redundant transceiver are provided in the illustrative embodiments. A determination is made in a redundant transceiver if electrical power is available over Ethernet. If power over Ethernet is available, power is received over Ethernet in the redundant transceiver, otherwise the redundant transceiver receives power from an attached power supply. For receiving power over Ethernet, the redundant transceiver remains in communication with the source of power over Ethernet using a wired section of the Ethernet, and the redundant transceiver receives electrical power to operate using the wired section of the Ethernet. The redundant transceiver receives power over Ethernet using a wire that is simultaneously carrying a data signal. When data signal and power are provided on a common wire, the redundant transceiver separates the electrical power from the data signal, uses the electrical power for operating the redundant transceiver, and uses the data signal for performing a function of the redundant transceiver.
