NOTE:
Once after the initial SED authentication, you can later modify the key by selecting
Dashboard (from the left menu), then select SED authorization icon from the System
section.
If both controllers are down after SED authentication is being configured then you will
prompted to re-enter the authentication key in middle of booting process. Rest of the
core modules will be loaded once the authentication key is verified again.
