Method and apparatus for notifying end user of excess power demand
First Claim
1. A method for notifying an end user of a powered device on an Ethernet based network that the powered device will not be powered due to an excess demand condition, the method comprising:
- detecting an attached powered device;
identifying an excess demand condition; and
temporarily supplying power to said detected attached powered device for a first predetermined time interval responsive to said identified excess demand condition thereby notifying an end user that the powered device is not being powered because of said identified excess demand condition, said supplied power being sufficient to fully power the attached powered device.

Abstract
A method and apparatus for notifying an end user of a powered device on an Ethernet based network that the powered device will not be reliably powered due to an excess demand condition comprising: detecting an attached powered device; identifying the class of the attached powered device, the class comprising the power requirements of the attached powered device; identifying an excess demand condition; and temporarily supplying power to the attached powered device for a time interval thereby notifying an end user that the powered device is not being reliably powered because of an excess demand condition.

21. An apparatus for notifying an end user of a powered device on an Ethernet based network of that the powered device will not be powered due to an excess demand condition, the apparatus comprising:
-
a powered device detector, for detecting an attached powered device connected thereto over communication cabling; an excess demand identifier associated with said powered device detector, for identifying an excess demand condition; a timer for timing a first predetermined time interval; and a power enabler associated with said excess demand identifier and said timer, said power enabler operative to temporarily supply power to said detected attached powered device for said first predetermined time interval responsive to said identified excess demand condition thereby notifying an end user that the powered device will not be powered because of said identified excess demand condition, said supplied power being sufficient to fully power said detected attached powered device. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A powered device adapted to sense an excess demand condition comprising:
-
a controller; a display associated with said controller; and a non-volatile memory associated with said controller, whereby said controller compares a current time marker with a time marker stored on said non-volatile memory, said stored time marker being associated with a powering up event, and in the event the difference between said current time marker and said stored time marker are less than a specified time interval displays a message indicating an excess demand condition on said display. - View Dependent Claims (41, 42)

43. A method for detecting an excess demand condition in a powered device, comprising:
-
obtaining a current time marker; comparing said current time marker with a previously stored time marker, said previously stored time marker being associated with a powering up of the powered device, thereby obtaining a time difference; and displaying an excess demand condition message in the event that said time difference is less than a specified time interval.

44. A method for detecting an excess demand condition in a powered device, comprising:
-
obtaining a current time marker; retrieving a last two previously stored time markers; comparing said last two previously stored time markers to obtain a first time difference; comparing the last of said last two previously stored time markers to said current time marker to obtain a second time difference; and displaying an excess demand condition message in the event that said first time difference is less than a first specified time interval, and said second time difference is less than a second specified time interval.
