POWER CONSERVATION IN POWER SOURCING EQUIPMENT |
| 摘要 |
A method is provided to conserve power in a power sourcing equipment (PSE) that provides a PSE port voltage at PSE ports. The method includes, in response to detecting a powered device (PD) is connected to the PSE port, providing a power supply output voltage at a default value and turning on the PSE port. After turning on the PSE port, the method includes determining the PSE port voltage. When the PSE port voltage is greater than a threshold value, the method includes decreasing the power supply output voltage. |

1. A method for a power sourcing equipment (PSE) to provide a PSE port voltage at PSE ports, comprising:
detecting a powered device (PD) is connected to a PSE port; in response to detecting the PD is connected to the PSE port:
providing a power supply output voltage at a default value; andturning on the PSE port; after turning on the PSE port, determining the PSE port voltage; and when the PSE port voltage is greater than a threshold value, decreasing the power supply output voltage. |
