This lets you upgrade the firmware of the SiteManager. You will be prompted to select a firmware file that you have saved on your local computer to send to the SiteManager. Rebooting is necessary to activate the new firmware.
Note 1: Once you have started the upgrade, you must wait for the upload of the file to finish before navigating elsewhere in the menus. This can take several minutes.
Note 2: Your **settings** will not be affected by an upgrade. This means e.g. that you will not automatically receive new built-in rules or a new factory default for a given parameter. Use the release notes to find new features and settings and decide whether or not you want to implement them manually (e.g. enter a new rule or change the value for a parameter to the new factory default).
Note 3: After a firmware upgrade, you may need to delete the cache (aka. "Temporary Internet Files") of your browser, in order for new **features** (e.g. new menu items and new fields) in the firmware to be displayed.
