Powered device in power-over-ethernet network system, and methods therefore
The present invention relates to a Powered Device (PD) in a Power-over-Ethernet (PoE) system. The invention proposes that the PD selectively transmit to a Power Sourcing Equipment (PSE) a power request based on the support of that PSE for autoclass. An autoclass supporting PSE will determine the maximum power that needs to be allocated to the PD based on measuring the power used by the autoclass supporting PD during classification. If the PSE does not support autoclass, it will instead allocate a default maximum power (based on the classification) to the PD. When the PD is operational it determines whether autoclass is supported by the PSE (230). If autoclass is supported then no power request should be sent (250) as otherwise the PSE will allocate power based on this request instead of on the more accurate measurement.
