An electrical substation management system maintains, and activates a backup device with, a backup configuration file if a primary device becomes inactive. Peer-to-peer communication may be used in an embodiment so that primary devices communicate with other devices so configured. A master device, such as a substation computer, in an embodiment may monitor status of all connected devices status, while a primary device or a backup device may monitor primary device or IED status and select a backup device for activation if a primary device changes status, and/or retain backup configuration files.
