Modules and extensions add parts or functionality to the system. Modules are fully supported parts of SUSE Linux Enterprise Server with a different life cycle and update timeline. They are a set of packages, have a clearly defined scope and are delivered via online channel only.
Extensions, such as the Workstation Extension or the High Availability Extension, add extra functionality to the system and require an own registration key that is liable for costs. Extensions are delivered via online channel or physical media. Registering at the SUSE Customer Center or a local registration server is a prerequisite for subscribing to the online channels. The Package Hub (Section 14.5, SUSE Package Hub) and SUSE Software Development Kit (Section 14.4, SUSE Software Development Kit (SDK) 12 SP3) extensions are exceptions which do not require a registration key and are not covered by SUSE support agreements.
A list of modules and extensions for your product is available after having registered your system at SUSE Customer Center or a local registration server. If you skipped the registration step during the installation, you can register your system at any time using the Section 20.9, Registering Your System.module in YaST. For details, refer to
Some add-on products are also provided by third parties, for example, binary-only drivers that are needed by certain hardware to function properly. If you have such hardware, refer to the release notes for more information about availability of binary drivers for your system. The release notes are available from http://www.suse.com/releasenotes/, from YaST or from /usr/share/doc/release-notes/ in your installed system.
