DISKSTATION MANAGER INSTALLATION

The first thing you should do is head over to the official Synology product support to download the latest available firmware/program versions (DSM 4.2).

Via the bundled Synology Assistant program you can see what IP the NAS is using to start the setup procedure.

Once you press install you will need to browse and locate the downloaded DSM file in your hard drive to proceed with the installation. This procedure will erase everything on the drive so make sure it's empty before pressing next.
