Overview

System software should be installed in the following cases:

• You replace the HDD with a new one (on which the System Software is not installed)
• You update to a more recent version of the system software (this is not necessary when you apply a patch; it is necessary when you install a major version change)
• You have trouble with the system software (e.g. software corruption) and the problem cannot be solved by performing "Factory Defaults", restoring the backup files, or restoring the factory default image.
