Smart Cache (FKA Turbo) uses the Egnyte Desktop App as a single interface for users, so if a device fails, the Desktop App automatically identifies this and services all requests directly to CFS without any user interference. 

However, if the Smart Cache (FKA Turbo) device fails to connect to the cloud in scenarios where the network connectivity is disrupted between the Smart Cache (FKA Turbo) and cloud, Desktop App users remain connected to the Smart Cache (FKA Turbo) device (offline mode).
