Control more than 1 Readynas to a Readynas with an UPS

Are you trying to control a second from the first or all four from a single UPS?

only 1 device can be connected to a UPS with the USB.
this is the 'master' device
the other devices that are plugged into the same UPS (but not by usb), you can go to frontview > system > power > ups configuration > enable monitoring of ups physically attached to remote readynas > ip of 'master' readynas (the one with the USB plugged into UPS).

Of course you'll need to connect the power cable for your router/switch to the UPS as well for this to work. A router/switch uses very little power and can be safely left to shutdown when the UPS battery runs out.

That is very true. I have a UPS connected to my backup NVX (192.168.1.202) and my primary NVX (192.168.1.201) monitors it (although I have not tested it, but hovering over the UPS icon in RAIDar on 201 displays the status of the UPS). However, the you must also enable sharing of the connection by listing the hosts enabled to monitor the connection. This is where I run into problems with my NV+ (203) for when I try to add the IP of the NV+ (192.168.1.203) in addition to the primary NVX (201) address, it is not accepted.

Since the NV+ is a partial second backup and temporary file storage, it does not have a high priority.

The problem I had is why I asked if the OP was trying to share the connection with one additional NAS (which I was successful with) or more than 1 (which I was not successful with).

Same here. Setup one Readynas with UPS (master) and a second one to control. This works great. But I want to add another to monitor (the third one). All devices and the switch are connected to the powersupply from the UPS.

Frontview 'talks' about units (plural) but when I try to add using comma or semicolon or slash it doesn't accept. So can we control more than one unit? If yes, how do we add the other ones in Frontview (master)?

You could specify the entire subnet e.g. 192.168.0.0/24 as the devices that you can share the UPS with.

Hi mdgm,

Hmmm...didn't thought of that...! I'll have a try and let you know the outcome.

Thanks!

That's what I do and it works flawlessly.

Have it up and running! Thanks again mdgm!
