Abstract

Aspects in accord with the present invention are directed to a system or method for changing power states of an uninterruptible power supply. In one aspect, the present invention features a method of monitoring a power state of a power device. The method may comprise receiving from one of a plurality of sources a request to change the power state of the power device, initiating a change of power state based on the request, logging an identity of the one of the plurality of sources requesting the change of power state, a type of change of power state, and a time of change of power state, and communicating through a user interface the identity of the one of the plurality of sources requesting the change.

Claims

1. A method of monitoring a power state of a power device, the method comprising:

receiving from one of a plurality of sources a request to change the power state of the power device;

initiating a change of power state based on the request; and

logging an identity of the one of the plurality of sources requesting the change of power state, a type of change of power state, and a time of change of power state.

2. The method of claim 1, further comprising communicating through an interface the identity of the one of the plurality of sources requesting the change.

3. The method of claim 2, wherein communicating includes communicating through a user interface the identity of the one of the plurality of sources requesting the change.

4. The method of claim 2, wherein communicating includes communicating through an application program interface the identity of the one of the plurality of sources requesting the change.

5. The method of claim 3, wherein communicating through a user interface includes communicating through an alphanumeric user interface the identity of the one of the plurality of sources requesting the change.

6. The method of claim 1, wherein initiating the change of power state includes communicating through the interface the request to change the power state and the identity of the one of the plurality of sources requesting the change of power state.

7. The method of claim 1, wherein initiating the change of power state includes initiating a shutdown of an outlet of the power device.

8. The method of claim 1, wherein initiating the change of power state includes initiating a powering off of the power device.

9. The method of claim 1, wherein initiating the change of power state includes initiating a sleep mode of the power device.

10. The method of claim 1, wherein initiating the change of power state includes initiating a reboot of the power device.

11. The method of claim 1, wherein initiating the change of power state includes initiating a reboot of an outlet of the power device.

12. The method of claim 1, wherein initiating the change of power state includes initiating a gradual shutdown of loads attached to the power device.

13. The method of claim 1, further comprising communicating through the user interface the type of change of power state.

14. The method of claim 1, further comprising communicating through the user interface the time of change of power state.

15. The method of claim 1, further comprising communicating a warning to a load impacted by the change of power state.

16. The method of claim 1, wherein initiating the change of power state includes:

powering off at least one group of outlets of the power device after a first time period has elapsed; and

powering off the power device after a second time period has elapsed.

17. A power device comprising:

a housing;

an input to receive power from a power source;

an output operatively coupled to the input and configured to provide power;

an interface; and

a controller coupled to the interface and configured to;

receive from one of a plurality of sources a request to change the power state of the power device;

initiate a change of power state based on the request; and

log an identity of the one of the plurality of sources requesting the change of power state, a type of change of power state, and a time of change of power state.

18. The power device of claim 17, wherein the controller is further configured to communicate through the interface the identity of the one of the plurality of sources requesting the change.

19. The power device of claim 17, wherein the interface is disposed within the housing.

20. The power device of claim 17, wherein the interface is a user interface.

21. The power device of claim 17, wherein the interface is an application program interface.

22. The power device of claim 20, wherein the user interface is an alphanumeric user interface.

23. The power device of claim 17, wherein in initiating the change of power state based on the request, the controller is further configured to communicate through the interface the request to change the power state and the identity of the one of the plurality of sources requesting the change of power state.

24. The power device of claim 17, wherein in initiating the change of power state, the controller is further configured to initiate a shutdown of an outlet of the power device.

25. The power device of claim 17, wherein in initiating the change of power state, the controller is further configured to initiate a powering off of the power device.

26. The power device of claim 17, wherein in initiating the change of power state, the controller is further configured to initiate a sleep mode of the power device.

27. The power device of claim 17, wherein in initiating the change of power state, the controller is further configured to initiate a reboot of the power device.

28. The power device of claim 17, wherein in initiating the change of power state, the controller is further configured to initiate a reboot of an outlet of the power device.

29. The power device of claim 17, wherein in initiating the change of power state, the controller is further configured to initiate a gradual shutdown of loads attached to the power device.

30. The power device of claim 17, wherein the controller is further configured to communicate through the user interface the type of change of power state.

31. The power device of claim 17, wherein the controller is further configured to communicate through the user interface the time of change of power state.

32. The power device of claim 17, wherein the controller is further configured to communicate a warning to a load impacted by the change of power state.

33. The power device of claim 17, wherein in initiating the change of power state, the controller is further configured to:

power off at least one group of outlets of the power device after a first time period has elapsed; and

power off the power device after a second time period has elapsed.

34. The power device of claim 17, further comprising a second input to receive power from a second power source.

35. The power device of claim 33, wherein the second power source is a battery,

36. The power device of claim 34, wherein the battery is included in the power device S.

38. The power device of claim 26, wherein the means for identifying the source of the request to change the power state includes means for communicating an identity of the source of the request to change the power state of the power device.

39. The power device of claim 26, wherein the means for identifying the source of the request to change the power state includes means for logging an identity of the source of the request to change the power state of the power device.
