Buffalo TeraStation Essentials - Before Configuring Failover; Usage Restrictions

Before Configuring Failover
Use the same LAN ports for transferring data and configure both TeraStations with static IP addresses for the
purposes of failover.
Using the Same LAN Port for Both File Sharing and Failover
Using this setup, if the main TeraStation fails, the backup TeraStation will replace it completely. The backup
TeraStation will be updated over normal network traffic.

Using Different LAN Ports Between File Sharing and Failover
With this setup, the backup TeraStation and main TeraStation are connected by a second Ethernet cable connecting
their LAN port 2. Updating is done over this dedicated network path, so updates are quicker and don’t interfere with
normal network traffic.
