by name, but will keep its original IP address.
Connecting to the network at LAN port 1 and setting failover at LAN port 2
The main and backup TeraStations should be the same model and capacity. Use fixed IP addresses for both TeraStations.
Because the IP address of the TeraStation designated as the backup cannot be changed, set its IP address before
configuring failover.
Using with UPS
Once failover is configured, you cannot set up a UPS for the backup TeraStation. Configure your UPS before configuring
failover. UPS recovery can be configured for both the main TeraStation and the backup TeraStation. However, the UPS
settings of the main TeraStation will not be copied to the backup TeraStation.
If the backup TeraStation is configured to sync with the UPS connected to the main TeraStation, then if the main
TeraStation shuts down, the backup TeraStation will no longer be able to detect if there was a power outage. In this case,
move the UPS communication cable from the main TeraStation to the backup TeraStation and reconfigure the UPS link
settings.
