Abstract
A data communications system (100) has a controller (214) for managing the system containing a plurality of data communications devices (224). The data communication devices (224) have memory allocated for storing controller configuration information in order to serve as distributed controller backup units (226). If the controller (214) is replaced by a replacement controller (228), the controller configuration information is restored to the replacement controller (228) which receives the controller configuration information previously stored in the memory of the data communication devices serving as distributed controller backup units. The controller configuration information is stored in a page format (390) having identification (391), controller configuration information data (392), and error detection information (393).
