QTS, QuTS hero, UPS systems with USB or SNMP support
Scenario
Power outages or voltage fluctuations can cause data corruption or system failure. By connecting a compatible UPS (Uninterruptible Power Supply) to your QNAP NAS, you can prevent data loss and perform a safe system shutdown when necessary. If you are unable to set a space alert threshold, your volume is probably a legacy volume created in QTS 4.0 or earlier versions, which do not support creating alert thresholds for an individual volume and other newer storage features.
Solution
Step 1: Choose a compatible UPS
Refer to the QNAP Compatibility List to verify that your UPS is supported by your NAS model.
Examples of compatible Smart UPS models:
| Brand | Model | Type |
|---|
| APC | SMT1000IC | Smart-UPS with USB |
| CyberPower | PR1500ELCD | Rackmount, USB/SNMP |
| Nitram | ELITE PRO 1000ELCDRT2U | Rackmount, USB |
| Eaton | 5PX1500iRT | Smart Line-Interactive |
| APC | SMX1500RMI2U | Rackmount, SNMP/USB |
Step 2: Connect the UPS to your NAS
Step 3: Configure UPS settings in QTS/QuTS hero
Go to Control Panel > System > External Device > UPS.
Enable the UPS support checkbox.
Choose from the following options:
Enable network UPS master (this lets other NAS systems follow shutdown instructions).
Shutdown NAS after X minutes of power loss (recommended duration: 3–5 minutes).
Enable notifications to receive alerts.
For SNMP-based UPS:
Select Network UPS.
Enter the UPS IP address and SNMP community string (usually public).
Test the connection.
Step 4: Test your setup
Unplug your UPS from the power source and verify the following:
The NAS can detect the UPS on battery.
The NAS can initiate a shutdown after the configured delay.
You can receive system logs or notifications about power loss and shutdown

场景
停电或电压波动可能导致数据损坏或系统故障。通过将兼容的UPS(不间断电源)连接到您的QNAP NAS,您可以防止数据丢失,并在必要时安全关闭系统。如果您无法设置空间警报阈值,您的卷可能是QTS 4.0或更早版本中创建的原有卷,这些版本不支持为单个卷创建警报阈值和其他较新的存储功能。
解决方案
步骤1:选择兼容的UPS
参考QNAP兼容性列表以验证您的UPS是否被您的NAS型号支持。
兼容的智能UPS型号示例:
| 品牌 | 型号 | 类型 |
|---|
| APC | SMT1000IC | 带USB的智能UPS |
| CyberPower | PR1500ELCD | 机架式,USB/SNMP |
| Nitram | ELITE PRO 1000ELCDRT2U | 机架式,USB |
| Eaton | 5PX1500iRT | 智能线交互式 |
| APC | SMX1500RMI2U | 机架式,SNMP/USB |
步骤2:将UPS连接到您的NAS
步骤3:在QTS/QuTS hero中配置UPS设置
前往控制台>系统>外部设备>UPS.
启用UPS支持复选框。
从以下选项中选择:
对于基于SNMP的UPS:
选择网络UPS.
输入UPS的IP地址和SNMP社区字符串(通常为public)。
测试连接。
步骤4:测试您的设置
拔掉UPS的电源插头并验证以下内容:
NAS可以检测到UPS在电池上。
NAS可以在配置的延迟后启动关机。
您可以接收到关于断电和关机的系统日志或通知
