NAS OS 4 SETUP
The first thing you need to do after plugging the NAS to your local network is to go to discover.seagate.com (you will need to have internet access for this - if not you can still start the setup procedure by using the MAC address of your NAS) to detect the NAS and start the installation.
Once the NAS is detected the setup wizard will detect any available firmware updates and install them.
Installation depends a lot on your internet speed but in our case it took around 4-6 minutes to download and install the update.
After that you just need to fill in your name, email and desired password (and the time zone if the one detected is not the right one) and you're good to go.
