This software image (universalk9-mz) serves as the unified operating system for multiple hardware platforms within the series, including the Cisco 921, 926, 927, and 931 routers. It provides a foundational IP Base feature set with the ability to activate advanced technology packages such as Security (SEC) and Application Experience (APP) through software licensing.
