摘要： Methods and apparatus are disclosed for balancing power across all conductors of an Ethernet connection. Balancing circuitry is disclosed to allow an Ethernet midspan device to receive power from an Ethernet Power Sourcing Equipment (PSE) on the signal pairs of an Ethernet connection. The balancing circuitry is configured to sense the level of the received power, and generate a second power source substantially equal to the received power level. The received power is provided to an Ethernet Powered Device (PD) over the signal pairs of an Ethernet connection, and the generated power to the PD over the unused pairs of the Ethernet connection.

摘要： Methods and apparatus for delivering power down all conductors of an Ethernet connection are disclosed. Embodiments include control circuitry coupled to both conductor of an Ethernet cable. The control circuitry is configured to sense the current flowing through power switches coupled inline with the respective conductors and control the switch in order to maintain the current flow through the power switch below a predetermined level. The circuitry prevents Ethernet ports from being shutting down due to conditions caused by imbalances in the effective resistance of Ethernet conductors and circuit paths.

摘要： A method and apparatus for changing power class for a powered device are provided. During operation, a powered device, such as an IP telephone, receives power from a power source via a PoE device. In the event that the powered device detects connection to a second powered device, such as an IP telephone module, the powered device transmits a classification signal to the power source. Based upon the classification signal, the power source performs a powered device classification procedure to reclassify the powered device, such as according to an IEEE 802.3af standard, and provide an increase amount of power to the powered device. The powered device, in turn, provides a portion of the power to the modular device. The modular powered device, therefore, receives power directly from the first powered device and does not require additional equipment in order to operate.

摘要： A power-sourcing equipment (PSE) has a powered communications interface to which a powered device (PD) is coupled. The PD presents a valid PD signature indicating that the PD is attached and capable of receiving normal operating power from the PSE. Per a power-withholding policy, the PSE operates in a power-withholding state to withhold the normal operating power notwithstanding the valid PD signature, and monitors for a signal via the powered communications interface indicating that the normal operating power should be delivered to the PD. The signal may be an alternative signature generated by a user-activated switch for example. In response to receiving the signal in the power-withholding state, the PSE enters a power-providing state in which it provides the normal operating power to the PD notwithstanding the power-withholding policy. An intermediate device (dongle) may be employed to generate the signal.
摘要翻译：电源设备（PSE）具有供电的通信接口，被动设备（PD）耦合到该通信接口。 PD提供一个有效的PD签名，指示PD已连接并能够从PSE接收正常的工作电力。根据电力扣缴政策，尽管有效的PD签名，PSE仍然处于停电状态，以保持正常的运行能力，并通过供电的通信接口监视信号，指示正常运行功率应送达PD 。信号可以是例如由用户激活的开关产生的替代签名。为了接收到处于停电状态的信号，PSE进入向PD提供正常操作电力的供电状态，尽管有预扣税政策。可以使用中间设备（加密狗）来产生信号。

摘要： Redundancy of data and/or Inline Power in a wired data telecommunications network from a pair of power sourcing equipment (PSE) devices via an automatic selection device is provided by providing redundant signaling to/from each of the pair of PSE devices, and coupling a port of one PSE device and a redundant port of the second PSE device to respective first and second interfaces of a port of the selection device. The selection device initially selects one of the two PSE devices and communicates data and/or Inline Power to a third interface of the selection device. A powered device (PD) coupled to that third interface communicates data and/or Inline Power with the selected one of the first and second PSE device through the selection device. Upon detection of a condition, such as a failure condition, the selection device may select the other of the two interfaces.
