Do I need UPS for Synology?
You need UPS protection for your router, switches and your desktop computer, if you’re using one. If you can’t connect them to the same UPS as the DiskStation, you’ll need separate ones. Due to its higher power requirements, it’s probably best to have a dedicated UPS for your desktop PC too.
What is Synology safe mode?
Safe Mode. When the Synology NAS enters Safe Mode, it stops all services and unmounts volumes in order to prevent data loss and shut down (halt for EDS14) safely when the UPS device runs out of power. By default, the system enters Safe Mode when the UPS device starts running low on power.
What size UPS do I need for my server?
When choosing a UPS, it is generally recommended you chose one with an output watt capacity 20-25% higher than the total wattage of the devices you want to connect. You can use the UPS watts calculator to determine your total load.
What happens to NAS when power goes out?
The NAS remains functional. The power is not restored, and the NAS is in auto-protection mode. The NAS stops all running services. All shared folders and iSCSI LUNs become inaccessible.
How many watts does Synology NAS use?

Is the Synology be600m1 enough for my ds418?
It will be more than enough as far as your DS418 is concerned. Hmm, having trouble locating the BE600M1 for the UK, and Synology seems to be more fussy about the DS418 than the other 18 Series devices, when it comes to rating its compatibility with the various UPSs. Don’t know why that should be.
Is the CyberPower br700elcd compatible with the ds418?
One device that is in the compatibility list for the DS418 is the CyberPower BR700ELCD, but curiously the list notes that “The UPS automatic shutdown feature is currently not supported”. Without that support, how can it even be considered compatible, or would it be talking about something other than the ability to trigger the NAS into action?
