How does the UPS communicate with my ReadyNAS?
There is a UPS setup option in my ReadyNAS and in the manual it says to setup a UPS either remotely or online. But how does it connect to a UPS itself? Does the UPS need to have an ethernet cable that plugs into my network? Does the UPS need to have a USB cable that plugs into the NAS?
In the ReadyNAS online doc it says that ANY UPS will automatically power down the ReadyNAS once the power goes out. This has me really confused. Does it sense that the line voltable changes when the power goes out and the UPS kicks in?
help. lol

UPS should have PowerChute USB port (like APC Back-UPS BE600M1). A cable will connect this port and NAS USB port. NAS will periodically check UPS, generate outage event and get shutdown decision.
NAS is able resend outage event to others NAS over ethernet. Router should be connected to UPS in this case.
Bear in mind, some UPS model haven't got PowerChute USB port (like APC Back-UPS BC650-RSX761). This case UPS is not able automatically power down the ReadyNAS. But script can help you with such UPS. Router should NOT be connected to UPS in this case.

This is the exact UPS I purchased, though I have not tried it out yet. The UPS manual says it will shut down a Windows pc, which made me question if it would shutdown a readnas system. I will try it out as soon as my nas is finished syncing. Once I plug the UPS into the readynas, I would imagine that the UPS section in the nas menu would recognize the UPS?Since the nas obviously can't launch the APC powerchute software, I was wondering if you first hooked it up to a windows pc to configure and then hooked it up to your NAS?

Yes.

I guess you could, though the settings might not be applied to the NUT interface. I use Cyberpower myself, and I've never bothered to install their management utilities.
BTW, if you want to share the UPS with a PC, you can install NUT on the PC, and monitor the UPS via the NAS. Or you can just let the PC shut down ungracefully when/if the UPS runs down.

NAS UPS has three implementation ways, they are respectively local USB UPS, remote USB UPS and SNMP UPS. The first two are connected via USB cable, the cable will connect UPS's port and NAS USB port. The third way - SNMP UPS, is through the ethernet, and must ensure the NAS and UPS in the same network segment.
If you choose local USB UPS, NAS will add records automatically, you can set shutdown threshold.
If you choose remote USB UPS, you will add this record manually, enter the IP address of the local NAS.
If you choose SNMP UPS, you will add this record manually, enter name(UPS)/Address(UPS' s IP address)/Community(public)/MIBs(specific models).

Not quite.
-The local UPS is connected via a USB cable that runs from the UPS to a ReadyNAS USB port. This uses a package called NUT (Network UPS Tools).
-You can also use share this local UPS - using it to protect a second (or third) "remote" NAS. These aren't very remote (they need to be powered from the same UPS). If you are sharing, the remote NAS all monitor the UPS via the local NAS. The remote NAS get their monitoring information over ethernet (from the local NAS). This remote monitoring also uses NUT, but the remote NAS are not using USB.
-If the UPS supports SNMP, it will have an ethernet connection to your network. These are usually fairly large UPS, intended to protect rack(s) of server equipment.
Whenever you are using ethernet to monitor a UPS, the UPS also needs to protect the ethernet equipment on the path. With a shared USB UPS, those are the paths between the local NAS and all the remote NAS. With an SNMP UPS, those are the paths between the UPS ethernet card and all the equipment that is monitoring the status of that UPS.
