Abstract
An inter-integrated circuit port comprising an electrical connector for communicatively coupling to an I2C bus and a controller coupled to the electrical connector. The controller controls data communication flow through the electrical connector, including preventing the electrical connector from unauthorized access to the data.
Claims19
An inter-integrated circuit port comprising:
- an electrical connector for communicatively coupling to an inter-integrated circuit bus;
- and
- a controller coupled to said electrical connector, said controller controls data communication flow through said electrical connector, including preventing information from being communicated to said inter-integrated circuit port if a field replaceable unit coupled downstream of said inter-integrated circuit port is not authorized to receive said information.
An inter-integrated circuit router comprising:
- a) a high-speed internal bus for communicating information;
- b) an inter-integrated circuit port coupled to said high-speed internal bus, said inter-integrated circuit port provides an interface for communicating information with an inter-integrated circuit bus segment wherein said inter-integrated circuit port stops said information from being communicated to said inter-integrated circuit bus if a field replaceable unit coupled downstream of said inter-integrated circuit port is not authorized to receive said information;
- and
- c) a high-speed external port coupled to said high-speed internal bus, said high-speed external port provides an interface to an external high-speed bus.
