UPS

A UPS can provide backup power to your NAS in the event of a power outage. Using a UPS can protect your data and NAS from sudden shutdown or service interruptions.

  • Network UPS: Here you can setup your NAS to be the network UPS server (Master mode) and set its IP address, when the UPS's USB cable is connected to your NAS. Other devices that are in the same local area network will be then set to slave mode. In the event of a power outage, the master and slave devices will immediately detect this stoppage in power and then determine whether or not to commence shutdown procedures based on the time period that has been set.
  • Shut down: When the NAS receives notification of a power outage from the UPS, it will begin normal shutdown procedures.
  • Safe mode: When the NAS receives notification of a power outage from the UPS, it will stop all services in accordance with normal procedures and unmount all storage volumes. If you have enabled the "In the event of a power outage, enable the NAS to return to its previous state once power has been restored" setting (configurable via Settings → Hardware → Power), once the NAS has been shut down under safe mode, it will automatically turn on once power has been restored.
