Connecting UPS to ReadyNAS
I am unable to connect my ReadyNas 314 to an APC - SMT1500 UPS (PowerChute- Business Edition). I am connected to PowerChute with my desktop via USB. I have the UPS on the network and I can ping it. ...

So a real network card isn't an option for your UPS model?
As I said in my initial response, you can do what you want using NUT. With NUT, one device is connected to the UPS via USB or serial port and is the master. Other devices powered by the same UPS can be slaves to that device since only one can talk directly to the UPS via USB or serial. The master must be always on and the last thing powered down, obviously, so that's usually the NAS. And NUT is what the ReadyNAS has built in. So instead of connecting the UPS USB to your PC, connect it to the NAS. Then install NUT on the PC, configure the NAS to allow other users to monitor its UPS, and set up the PC to do just that.
That does mean you no longer can use PowerChute with the UPS since APC offers no Linux version except the insanely expensive enterprise version, but you would still have SmartConnect to see anything that NUT doesn't give you insight into.

As a tidbit, Eaton does have a Linux version of it's monitoring software, and one instance can be master and others slaves. But it still works out better to use a network card for multiple devices.
Thank you for the response. What I have is the SmartConnect network interface which supports monitoring the UPS through their web portal. I didn't realize the interface couldn't be used for anything else, my mistake.
What I'm trying to accomplish here is I want my ReadyNAS to be commanded to shut down when local power drops and the UPS is running on battery. Is their a way that I can accomplish this? I thought thats what interfacing the NAS and UPS would do for me. If not I'll creat another thread and ask. Thank you
