Abstract

According to one system, the system includes a chassis defining an enclosure and containing one or more slots. The system further includes a radio frequency identification (RFID) reader module comprising at least one processor and one or more RFID readers located within the enclosure, wherein the one or more RFID readers are configured to read data stored in RFID tags associated with one or more unpowered network taps. The RFID reader module is configured to receive, from a first RFID reader associated with a first slot of the chassis, information regarding a first unpowered network tap in the first slot, to determine, using a known location of the first RFID reader, a slot identifier associated with the first unpowered network tap, wherein the slot identifier indicates that the first unpowered network tap is in the first slot, and to provide the information and the slot identifier to a management system.

Claims

1. A method for obtaining information regarding unpowered network taps, the method comprising:

in a chassis defining an enclosure and containing two or more slots,

providing a radio frequency identification (RFID) reader module comprising a first RFID reader and a second RFID reader located within the enclosure, wherein the first RFID reader is configured to read RFID tag data associated with a first slot of the chassis and the second RFID reader is configured to read RFID tag data associated with a second slot of the chassis and to read RFID tag data associated with a third slot of the chassis;

receiving, from the second RFID reader, information regarding a first unpowered network tap in the second slot;

determining, using a known location of the second RFID reader and the information regarding the first unpowered network tap, a slot identifier associated with the first unpowered network tap, wherein the slot identifier indicates that the first unpowered network tap is in the second slot; and

providing the information and the slot identifier to a management system.

2. The method of claim 1 wherein the first RFID reader uses a directional antenna.

3. The method of claim 1 wherein the first RFID reader uses a frequency for covering a range of less than 2 centimeters or uses a frequency between 125 kilohertz (kHz) and 13.56 megahertz (MHz).

4. The method of claim 1 wherein the first RFID reader uses an internal antenna or an external antenna.

5. The method of claim 1 wherein the first unpowered network tap includes an optical network tap.

6. The method of claim 1 wherein a first RFID tag associated with the first unpowered network tap includes static information associated with the unpowered first network tap and one or more unique identifiers for identifying the first RFID tag.

7. The method of claim 6 wherein the static information includes a model type, a serial number, a model number, a date of manufacture, a location of manufacture, network speed information, a split ratio, and/or insertion loss information.

8. The method of claim 1 wherein providing the information and the slot identifier to the management system is in response to receiving a request for the information from the management system.

9. A system for obtaining information regarding unpowered network taps, the system comprising:

a chassis defining an enclosure and containing two or more slots;

a radio frequency identification (RFID) reader module comprising at least one processor and a first RFID reader and a second RFID reader located within the enclosure, wherein the first RFID reader is configured to read RFID tag data associated with a first slot of the chassis and the second RFID reader is configured to read RFID tag data associated with a second slot of the chassis and to read RFID tag data associated with a third slot of the chassis; and

wherein the RFID reader module is configured to receive, from the second RFID read, information regarding a first unpowered network tap in the second slot, to determine, using a known location of the second RFID reader and the information regarding the first unpowered network tap, a slot identifier associated with the first unpowered network tap, wherein the slot identifier indicates that the first unpowered network tap is in the second slot, and to provide the information and the slot identifier to a management system.

10. The system of claim 9 wherein the first RFID reader uses a directional antenna.

11. The system of claim 9 wherein the first RFID reader uses a frequency for covering a range of less than 2 centimeters or uses a frequency between 125 kilohertz (kHz) and 13.56 megahertz (MHz).

12. The system of claim 9 wherein the first RFID reader uses an internal antenna or an external antenna.

13. The system of claim 9 wherein an external antenna includes signal traces on a printed circuit board.

14. The system of claim 9 wherein the first unpowered network tap includes an optical network tap.

15. The system of claim 9 wherein a first RFID tag associated with the first unpowered network tap includes static information associated with the first unpowered network tap and one or more unique identifiers for identifying the first RFID tag.

16. The system of claim 15 wherein the static information includes a model type, a serial number, a model number, a date of manufacture, a location of manufacture, network speed information, a split ratio, and/or insertion loss information.

17. The system of claim 9 wherein the at least one processor is configured to provide the information and the slot identifier to the management system is in response to receiving a request for the information from the management system.

18. A non-transitory computer readable medium having stored thereon executable instructions embodied in the computer readable medium that when executed by at least one processor of at least one computer cause the at least one computer to perform steps comprising:

in a chassis defining an enclosure and containing two or more slots,

providing a radio frequency identification (RFID) reader module comprising a first RFID reader and a second RFID reader located within the enclosure, wherein the first RFID reader is configured to read RFID tag data associated with a first slot of the chassis and the second RFID reader is configured to read RFID tag data associated with a second slot of the chassis and to read RFID tag data associated with a third slot of the chassis;

receiving, from the second RFID reader, information regarding a first unpowered network tap in the second slot;

determining, using a known location of the second RFID reader and the information regarding the first unpowered network tap, a slot identifier associated with the first unpowered network tap, wherein the slot identifier indicates that the first unpowered network tap is in the second slot; and

providing the information and the slot identifier to a management system.
