Logging In and Initial Setup
Synology offers a piece of software that you run on your main computer to manage your NAS. The software is called Synology Assistant and with it you get to see the Synology products on your network.
Before you can begin to configure your NAS you need to point the Assistant software to a copy of the firmware / software that you want loaded on your NAS. By going to Synology's website you can choose the newest version from your NAS product download page.
After the software is loaded to the NAS you are asked a couple of questions and can setup your storage array.
Before you do anything crazy, the Assistant software reminds you that the data on your HDDs will be erased in the format process.
This is also when you configure your network. If you don't know anything at all about your home network you don't need to worry, Synology has an easy setting that handles it all for you.
After these five steps are finished, the Assistant software goes to work formatting the drives, building your array and applying your network settings.
