Power on the unit and complete initial setup through the Synology DiskStation Manager (DSM) web interface: create storage pools, configure RAID or hybrid modes, set up shared folders, user accounts and scheduled backups. Configure network settings for redundancy or link aggregation if supported by your network switch.

Recommendations

For reliable operation, use enterprise- or NAS-rated drives, keep DSM and firmware updated, and implement a backup strategy that copies critical data off the device. Verify drive health periodically and consider using RAID levels that match your redundancy and capacity needs. Note the unit is sold unpacked and has scratches on the bottom, so inspect physical condition on receipt.
