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.

摘要： Redundancy of data and/or Inline Power in a wired data telecommunications network from a first network device and a second network device configured as power sourcing equipment (PSE) devices and coupled together and to a third network device (such as a PD) via a Y device is provided by providing redundant signaling to/from each of the pair of network devices, and coupling a port of each of the network devices to the Y device and from there to a third port where a third network device such as a PD may be coupled. Because the Y device is essentially passive, communications paths between the PSE devices and the PD are provided for negotiating master/slave status and other status and related information among the respective network devices. Dynamic impedance matching is provided to handle situations where not all devices are plugged in and as a communications technique among the devices.

摘要： Methods and apparatus for determining that all conductors of an Ethernet connection are connected to the same powered device (PD). In one disclosed embodiment, it is first determined that a signal conductor pair of the Ethernet connection is coupled to a valid PD according to a discovery process, and the unused conductor pair of the Ethernet connection is also coupled to a valid PD. However, it is not yet determined whether they are both coupled to the same PD. This disclosure provides for injecting a polluting signal into one of the conductor pairs, and performing the discovery process on the other conductor pair. If the discovery process fails on the other conductor pair as a result of the polluting signal, then it is determined that both of the conductor pairs are indeed coupled to same PD.

摘要： A system provides for indicating/detecting multiple powered devices connected to a power delivery channel of a power sourcing equipment, so that power can be coherently shared among the powered devices. A first operation includes (a) applying a standard first detection signal (such as a detection voltage) to the power delivery channel and (b) detecting and interpreting a second detection signals (such as a detection current) which in a standard response would be either zero or a predetermined value indicating the presence of a single powered device. The interpreting includes determining whether the second detection signal indicates that multiple powered devices may be connected, for example by detecting current values of n*Idet or Idet/n, where n is an integer greater than one. A second operation includes (c) providing a plurality of distinct signals to the power delivery channel, each eliciting a distinct individual response signal from a corresponding powered device, and (d) detecting each distinct individual response signal to identify the powered devices connected to the power delivery channel. The distinct signals may be non-standard classification signals or other specialized signals to elicit the individual responses.
