How do I use a UPS with my QNAP NAS?

Hvordan bruger jeg en UPS med min QNAP NAS?

Last modified date: 2025-06-27

Applicable Products

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

Via USB:
Plug the UPS USB cable into the NAS USB port. You NAS will detect the UPS automatically.
Via SNMP (Network UPS):
Connect the UPS to your network and configure SNMP settings on the 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

Scenarie

Strømafbrydelser eller spændingsudsving kan forårsage datakorruption eller systemfejl. Ved at tilslutte en kompatibel UPS (Uninterruptible Power Supply) til din QNAP NAS kan du forhindre datatab og udføre en sikker systemnedlukning, når det er nødvendigt. Hvis du ikke kan indstille en pladsadvarselsgrænse, er dit volumen sandsynligvis en Ældre diskenhed oprettet i QTS 4.0 eller tidligere versioner, som ikke understøtter oprettelse af advarselsgrænser for et individuelt volumen og andre nyere Lager funktioner.

Løsning

Trin 1: Vælg en kompatibel UPS

Henvis til QNAP-kompatibilitetsliste for at verificere, at din UPS understøttes af din NAS-model.

Eksempler på kompatible Smart UPS-modeller:

Mærke	Model	Type
APC	SMT1000IC	Smart-UPS med USB
CyberPower	PR1500ELCD	Rackmount, USB/SNMP
Nitram	ELITE PRO 1000ELCDRT2U	Rackmount, USB
Eaton	5PX1500iRT	Smart Line-Interactive
APC	SMX1500RMI2U	Rackmount, SNMP/USB

Trin 2: Tilslut UPS'en til din NAS

Via USB:
Sæt UPS'ens USB-kabel i NAS'ens USB-port. Din NAS vil automatisk registrere UPS'en.
Via SNMP (Netværks-UPS):
Tilslut UPS'en til dit netværk og konfigurer SNMP-indstillinger på NAS'en.

Trin 3: Konfigurer UPS-indstillinger i QTS/QuTS hero

Gå tilKontrolpanel>System>Ekstern enhed>UPS.
AktivérUPS-understøttelseafkrydsningsfeltet.
Vælg mellem følgende muligheder:
- Aktivér netværks-UPS-master(dette lader andre NAS-systemer følge nedlukningsinstruktioner).
- Luk NAS ned efter X minutter uden strøm(anbefalet varighed: 3–5 minutter).
- Aktivér notifikationerfor at modtage advarsler.

For SNMP-baseret UPS:

VælgNetværks-UPS.
Indtast UPS'ens IP-adresse og SNMP-community-streng (normaltpublic).
Test forbindelsen.

Trin 4: Test din opsætning

Tag UPS'en ud af strømkilden og verificer følgende:

NAS'en kan registrere UPS'en på batteri.
NAS'en kan starte en nedlukning efter den konfigurerede forsinkelse.
Du kan modtage systemlogfiler eller notifikationer om strømtab og nedlukning
