Lenovo Diskless 4-Bay Rackmount NAS

Is this a turnkey system? Do I just add 1 to 4 drives and it is ready to go? Or is the setup much more involved?

I was trying to find a manual for this thing … may be I did not look hard enough.

Per the vendor:

Depends on if the customers wants RAID. If not, they just can add drives, plug it in and connect to their network and the Server or PC will see the drives as network drives. If the customer wants RAID/Mirroring/Striping, then it can get a bit more technical. Once the customer adds the drives, they will need to choose which level of RAID they want and configure the system for that. If the customer calls Lenovo support, They can help walk them through the setup.
