UPS
An Uninterruptible Power Supply (UPS) is a power backup system that ensures continuous electricity during outages, preventing downtime and damage.
TrueNAS uses NUT (Network UPS Tools) to provide UPS support. For supported device and driver information, see their hardware compatibility list. Further device-specific compatibility information is available from the NUT Devices Dumps Library.
Report UPS bugs and feature requests to the NUT project.
Connect the TrueNAS system to the UPS device. To configure the UPS service, go to System > Services, finding UPS, and click edit.
