The tool will search for ASUSTOR servers on the network. When it finds ours, it will recommend that we set it up. Which of course we will do!
Since you already installed hard drives earlier, this screen is not really that important…just remember that all data on the drives will be wiped and do not shut off power during the installation. Click the arrow on the right to continue.
Select automatic firmware updates and click the arrow on the right.
The download failed; I later realized that this was due to my router (Linksys EA6500) not being compatible. (More on this in the Installation Verdict section). I clicked on the left arrow and manually updated ADM. A word of warning: in IE11, clicking on the download link brings up the firmware file in the browser instead of downloading the image file. Unless you want to read the firmware file, click on Save Target As to save the image file off to somewhere that the tool can read. (I saved this to my LaCie 5big NAS Pro; stay tuned for a long-term review update on that one too!).
