Applicable Products:
- All QTS / QuTS hero Firmware Versions
- All NAS Series
QTS & QuTS hero can handle the following UPS events:
| UPS event | NAS Status | NAS Action |
|---|---|---|
| OnLine (OL) | Normal | None |
| OnSmartBoost (OSB) | Normal | None |
| OnBatteryTest (OBT) | Normal | None |
| OnBattery (OB) | Abnormal | Auto-protection or Shutdown |
| Off (OFF) | Abnormal | Shutdown NAS |
UPS status notes:
- QNAP devices normally check the UPS status every 15 seconds.
- Upon detecting OB status (and the NAS is not in battery test mode), the device enters either an Auto-protection or Shutdown mode depending on the configured power failure period settings.
- If the UPS is in low-battery mode, the Auto-protection or Shutdown countdown period is automatically set to 30 seconds.
- In Auto-protection or Shutdown mode, the device checks the UPS status every 5 seconds until powered off.
- The NAS returns to normal status when the UPS status returns to Online (OL).
