Inline power policing
First Claim
1. A method for policing inline power, the method comprising:
- monitoring power drawn by one or more powered devices at power sourcing equipment, each of the one or more powered devices having a policing limit associated therewith;
if power drawn by one of the powered devices exceeds the policing limit for the powered device;
determining if a power budget of the power sourcing equipment has been exceeded;
if said power budget has not been exceeded, continuing to provide power to the one or more powered devices; and
if said power budget has been exceeded, initiating an action at the power sourcing equipment;
wherein initiating an action comprises requesting at least one of the powered devices to operate in a low power mode and removing power from one of the powered devices if the powered device requested to operate in a low power mode does not switch to said low power mode.

Abstract
In a wired data telecommunication network power sourcing equipment coupled to a powered device performs policing of power drawn by the powered device. In one embodiment, a method includes monitoring power drawn by the powered devices at power sourcing equipment, each powered device having a policing limit associated therewith. If power drawn by one of the powered devices exceeds the policing limit, it is determined if a power budget of the power sourcing equipment continues to provide power to the powered devices. If the power budget has been exceeded, action is initiated at the power sourcing equipment. The action may include sending or logging a warning, requesting the powered device to reduce its power requirement or removing power from one of the powered devices. An apparatus for policing inline power is also disclosed.

10. Apparatus for policing inline power, the apparatus comprising:
-
power sourcing equipment operable to provide inline power to one or more powered devices, each of the powered devices having a policing limit associated therewith; a monitor configured to monitor power drawn by the one or more powered devices; a controller configured to detect one or more of the powered devices exceeding the policing limit and determine if a power budget of the power sourcing equipment has been exceeded, if said power budget has not been exceeded, continue to provide power to the one or more powered devices, and if said power budget has been exceeded, initiate an action at the power sourcing equipment; and a memory for storing said policing limits and said power budget; wherein said action comprises requesting at least one of the powered devices to operate in a low power mode and the controller is configured to remove power from the powered device requested to operate in a low power mode, if the powered device does not switch to said low power mode. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
