Under the UPS tab, you can enable UPS support to prevent data loss when an unexpected power failure occurs.

To enable local UPS support:

1Connect a local UPS to the USB port of your DiskStation.

2Tick the Enable UPS support checkbox.

3Set the Time before DiskStation enters Safe Mode.

Note: If the local UPS is low on battery, or the network UPS server enters Safe Mode, DiskStation will ignore the specified time period and enter Safe Mode immediately.

4You can decide whether to send a shutdown signal to the UPS when the system enters Safe Mode. Most UPS can restore power supply automatically when the power recovers.

5Click OK.

Term Explanation

When entering Safe Mode, the system will first stop all services and unmount all data volumes to prevent data loss, so that when the UPS shuts down, the system will be turned off safely. If the Power Recovery function has been enabled, the system will restart automatically when power is restored.

To enable network UPS support:

1Tick the Enable UPS support checkbox.

2Enter the Network UPS server IP. (Make sure the server allow connection from Synology DiskStation)

3Set the Time before DiskStation enters Safe Mode.

4Click OK.
