ReadyNAS Duo with APC ES 450 UPS
Goal: Protect Duo against improper shutdown due to power failure.
Current situation: Duo power cord plugged into APC UPS unit along with some other hardware (external drives, monitor). UPS monitored by MacBook Pro. UPS battery fully charged.
Questions: How do I set it up so that a power failure will trigger graceful shutdown? I've selected the option in Frontview ("Enable monitoring of UPS physically attached to a remote ReadyNAS"), but I'm not sure if my UPS has an IP address. Or whether "monitoring" is the same as gracefully shutting down upon power failure....
Any help or pointers greatly appreciated. Thank you!

- It easier then you think.
What you need to do is connect power and usb cable from your UPS to your Nas and that's it.
You can also change the battery threshold when Nas should be powered down.
Option "Enable monitoring of UPS physically attached to a remote ReadyNAS" allows you to have 2 or more ReadyNas units (or PC) monitored and shutdown via network.
If you use this, don't forget to connect your ethernet switch/router power to the same UPS! Otherwise the NAS won't shut down when the UPS battery drains.bbaraniec wrote: Option "Enable monitoring of UPS physically attached to a remote ReadyNAS" allows you to have 2 or more ReadyNas units (or PC) monitored and shutdown via network. - Good point. The router/switch uses very little power and can be safely left to shutdown once the UPS battery has drained, but its power must be connected to the UPS. The shutdown commands are sent to the NASes well before the UPS battery has finished draining to give enough time for the units to shutdown. With at least some APC units you have the option of setting when you want the shutdown to occur.
- Thank you, Bartek -- worked perfectly. Much appreciated.
