Abstract

A system and method for providing automatic or semi-automatic identity association between an outlet of an intelligent power distribution unit and a target device, such as a computer server, which is powered by that outlet. The association is accomplished by enabling identification information to be transmitted between a memory device near or within the target device and the intelligent power distribution unit via a power cable. The power cable may include a specialized interface for mating with the power distribution unit and/or providing the identification information.

Claims

a receiver for receiving said identification information from said identification device via said cable connected to said specific power outlet; and

a management processor for associating said identification information with identification information for said specific power outlet,

wherein said identification device is programmable with identification information using a programming device, said programming device being configured to wirelessly receive identification information of said target device and to transfer said identification information to said identification device.

2. The system of claim 1, wherein said cable includes at least one additional conductor in addition to those conductors providing power to said target device, said additional conductor used to provide said communication of said identification information.

3. The system of claim 2, wherein said at least one additional conductor couples to said power distribution unit by way of one or more contacts provided proximate a connector of said cable.

4. The system of claim 3, wherein said contacts couple to said power distribution unit in an area outside of a conventional receptacle attachment area.

5. The system of claim 4, wherein said contacts couple to said power distribution unit through a lock mechanism that secures said cable to said power distribution unit.

6. The system of claim 1, wherein said identification information is communicated from said identification device to said power distribution unit using at least one power conductor, said receiver receiving said identification information from said power conductor.

7. The system of claim 6, wherein said receiver includes a filter for separating said identification information from an AC signal.

8. The system of claim 1, wherein said power distribution unit is operable to provide identification information to said identification device.

9. The system of claim 1, further including a field association device for receiving the identification information from the target device and identification information from the identification device and making an association therein, wherein association information regarding said target device and said corresponding identification device is electronically transferable for use by a management system for monitoring said intelligent power distribution units.

10. The system of claim 1, wherein said power cable includes a selectively operable visual or audible indicator at a target end thereof.

11. The system of claim 1, wherein said identification information regarding said target device is automatically provided from said target device to said intelligent power distribution unit.

12. The system of claim 1, wherein said programming device comprises a wireless receiver selected from the group consisting of barcode scanners and RFID readers.

13. A method of making an association between a target device and a specific electrical outlet of an intelligent power distribution unit providing power to said target device, said method comprising the steps of:

receiving a signal providing identification information of said target device at an identification device located proximate said target device, wherein said identification device is provided with said signal by a programming device that is operable to wirelessly receive identification information regarding said target device and transfer said identification information to said identification device;

storing said identification information of said target device at said identification device; and

communicating said identification information over a cable that is coupled to said specific electrical outlet and supplies power to said target device, such that an accurate association and monitoring of a target device having power supplied by the specific outlet may be made.

14. The method of claim 13, wherein said cable includes at least one additional conductor for communicating said identification information.

15. The method of claim 14, wherein said at least one additional conductor couples to said power distribution unit via a lock apparatus adjacent to AC power connection at said power distribution unit.

16. The method of claim 13, wherein said identification device is programmable with identification information using a field programming device, said field programming device operable to receive identification information regarding said target device and transfer said identification information to said identification device.

17. The method of claim 13, further including receiving identification information from a target device and a corresponding identification device at a field association device and making an association therein, wherein association information regarding said target device and said corresponding identification device is electronically transferable for use by a management system for monitoring said intelligent power distribution units.

18. The method of claim 13, wherein said programming device comprises a wireless receiver selected from the group consisting of barcode scanners and RFID readers.

19. An apparatus used to associate a target device having power supplied by an intelligent power distribution unit with a specific outlet of said power distribution unit, said apparatus comprising:
