Answer

Yes. When high availability (HA) is enabled, you can use UPS (uninterruptible power supply) for your NAS devices to minimize risks caused by sudden power outages. UPS provides a buffer that allows the system to perform controlled shutdowns and helps prevent data loss or service interruption.

To configure UPS settings, go to Control Panel > System > External Device > UPS.

Note

If you want your HA setup to remain operational during a power outage, we recommend preparing a separate UPS device for each node. This ensures that both the active and passive nodes have independent and stable power supplies.
