Abstract

A communication port identification system enables an intelligent interconnect patch panel to reliably track connections to network switches. Network switch ports are provided with port ID modules that are inserted into the ports. Intelligent interconnect patch cords each utilize a patch cord microcontroller and out-of-band conductors to enable communication between an intelligent interconnect patch panel and the port ID modules of the switch port. Each port ID module is provided with a unique identification number, and the intelligent interconnect patch panel is thereby able to track all of its connections to the port ID modules in real time, and to update a network management system accordingly.

Claims

1. A system for identifying ports in a communication system, comprising:

a network switch having a plurality of network switch ports;

an intelligent interconnect patch panel having a plurality of patch panel ports;

at least one intelligent interconnect patch cord connected between one of said network switch ports and one of said patch panel ports; and

a plurality of port ID modules, each of said port ID modules being inserted within one of said network switch ports and having a unique port ID code associated therewith.

2. The system of claim 1 wherein said intelligent interconnect patch cord comprises at least two out-of-band conductors.

3. The system of claim 2 wherein said intelligent interconnect patch cord comprises a switch plug and a patch panel plug.

4. The system of claim 3 wherein said out-of-band conductors are in electrical communication with port ID module plug contacts of said switch plug of said intelligent interconnect patch cord.

5. The system of claim 4 wherein each of said port ID modules comprises port ID module contacts that are adapted to be in electrical contact with said port ID module plug contacts of said switch plug of said intelligent interconnect patch cord.

6. The system of claim 1 wherein said intelligent interconnect patch panel comprises a patch panel microcontroller adapted to receive said unique port ID code of a port ID module when said intelligent interconnect patch cord is plugged into a switch port having said port ID module installed therein.

7. The system of claim 1 wherein each of said port ID modules comprises a printed circuit board on which said unique port ID code is stored.

8. The system of claim 7 wherein each of said port ID modules comprises two port ID module contacts electrically connected to said printed circuit board.

9. The system of claim 8 wherein said port ID module contacts may be shorted together in a disabling operation.

10. The system of claim 9 wherein said disabling operation results when one of said port ID modules is tampered with or removed from its corresponding switch port.
