Abstract: A system and method of analyzing a powered device (PD) in a Power-over-Ethernet (PoE) system are presented. The system includes an Ethernet interface having a physical layer (PRY) chip capable of providing a signal pulse in addition to physical layer 1 functions. The system further includes a pulse transformer, coupled to the PRY chip, capable of relaying the signal pulse provided by the PRY chip to the PD via the transmit line and a second PRY chip. The first PRY chip receives one or more return pulse signals from the PD, analyzes characteristics such as voltage and/or frequency of the return pulse signal(s), and determines attributes of the PD based on those characteristics. The attributes can include powered device validity and power classification. A method of supplying power to a PD is also presented.

The PSE interface includes a multi-port transmission line connector capable connecting to multiple Ethernet transmission lines, and a power source equipment (PSE) controller module integrated with the multi-port transmission line connector. The PSE controller module is capable of semi-automatic mode and legacy detection of one or more of the PDs that are coupled to the Ethernet transmission lines. The PSE controller module includes a plurality of PSE controllers corresponding to the Ethernet transmission lines, including a master PSE controller and plurality of slave PSE controllers coupled to the master PSE controller. The master PSE controller controls the slave PSE controllers, so as to provide power management to said corresponding PD devices, without an external microcontroller. In another embodiment, the PSE controller(s) inside the connector are configured for fully automatic mode, and include the feature of independent power management.

Abstract: A system and method for communicating information using Layer 1 from a powered device to power source equipment via Ethernet. In one embodiment, Layer 1 information such as power management, classification, temperature, and disconnect information is transmitted from a powered device to power source equipment using an AC signal that has a cycle defining a first time period during which the AC signal is turned on and a second time period during which the AC signal is turned off. A type of information being sent by the powered device can be determined based on characteristic on/off times of the AC signal cycle.
