Embodiments of this invention comprise a modular, scalable architecture for building a variety of Layer 2/3/4+ Ethernet products and devices. Such devices comprise of a set modules. The invention provides a set of rules to handle such modules. The rules are controlled by the architectural component named card manager. The card manager uses a protocol to discover the modules that are entering or leaving the system/device. The protocol's data provides a unique way of identifying the modules that belong to the system.
