Overview

DSM reads UPS status over USB or network and can trigger automatic shutdown when battery is low or on timer thresholds.

Enable UPS monitoring

Connect the UPS and confirm DSM detects it.

• Attach the UPS USB cable to the NAS or configure a network UPS
• Open Control Panel and enable UPS support
• Set safe shutdown at a battery level or time on UPS

Email and push alerts

Alerts help you react quickly when power events occur.

• Configure email or push notifications in Notification settings
• Enable alerts for AC loss, low battery, and shutdown events
• Send a test alert and verify it reaches the right people

Network UPS server for multiple devices

Share one UPS with multiple NAS units using DSM as a network UPS server.

• Enable the network UPS server on the NAS connected to the UPS
• Authorize client devices by IP or hostname
• On each client NAS, select Network UPS and point to the server

Logging and reports

Keep a basic record of power events for audits and troubleshooting.

• Review System Logs for UPS messages
• Export logs quarterly and keep them with maintenance notes
• Record battery replacement dates and UPS tests

Testing and drills

Validate behaviour before you depend on it.

• Simulate a brief outage by unplugging UPS input and observe events
• Confirm clean shutdown at the configured threshold
• Retest after firmware or configuration changes
