• Connect the NAS to your network using a standard Ethernet connection. For best results, connect to a switch or router capable of handling your office traffic and ensure the network is configured to allow discovery.
• Power on the device and locate its IP address via the router’s DHCP client list or the Buffalo discovery utility. Open a web browser and enter the IP address to access the web-based setup wizard.
• Follow the setup wizard to define the administrator credentials, configure RAID, create shared folders, and set up user accounts and access permissions. Establish backup jobs (local, network, or cloud-based if supported) and apply any security policies or access controls your organization requires.
• Test access from a client computer by mapping a network drive (Windows) or mounting the shared folder (macOS/Linux), and run a sample backup to confirm the system is correctly configured. Periodically review health and status reports in the admin interface to ensure continued reliability.
