In this video we demonstrate how to setup and configure an Uninterruptible Power Supply on a Synology NAS. An Uninterruptible Power Supply or UPS, is a device that will provide power to an electrical appliance in the event of a mains power failure.
If your energy supply is reliable, you may not need to purchase or use a UPS. However in the last few years as energy has become more expensive, it has also become less reliable. So if our NAS was accessing data at the time of a sudden outage or a power surge, that data could become damaged. In turn this damage could lead to the corruption of the operating system, or some of the files stored on our NAS. So in order to protect our data we need to use something like the APC Smart UPS SMT750i with our Synology NAS.
Notes: A secondary weapon to protect you from data corruption is to make regular backups. However, you need to also regularly check that you can recover your data from your backups. So we recommend that twice a year you practise recovering random files.
Notes: When you first setup a APC 750i, you might be asked for the Voltage Output. So if you live in the United Kingdom, you should set the voltage to 230v which is the European Harmonised Standard.
Quick reference notes:
- First connect your UPS to your Synology NAS
- Log into Disk Station Manager (DSM) with administrators privileges
- Load Control Panel – System – Hardware & Power
- Under the UPS tab ensure that the NAS has detected the UPS
- Tick the option, Enable UPS Support
- Make sure that Shutdown UPS when the system enters Safe Mode is ticked
- Select Apply
- Test that your UPS is working correctly
Additional resources required:
- A UPS compatible with your model of NAS. We use a APC Smart UPS SMT750i
