Do you have a RMCARD205 card in the UPS?
No. That costs more than the UPS itself did.
Used ones aren't too bad on ebay but what's this going to do for me that the USB interface doesn't?
Hard to tell on this UPS what is supported when you add the card. Ebay has them between 100 and 150. Looks like some really good features.
In the software are you able to toggle the load outlets? Does it support sleep and restart with delay recharged capacity? The card supports these, but I don't know if that unit can do it.
I don't run one of these. I have a different brand. I delay the restart until I have what I think is enough battery capacity to support the whole start and graceful shutdown.
If you can put it in sleep mode it should power off the outlets.... but I don't know if you can do that.
Cards like this make it possible to do some things from the UPS. They also permit non attached systems to control them. You can obviously shut down the UPS from network. Can you do that over USB?
I'm not saying its a silver bullet or anything. I was just curious. There are options. I think the price point on that unit is crazy low ..so super value. I think the one I am running is literally 25x the price new. Even with the card it's still really inexpensive. The APC for my desktop is still more.
No idea. The USB port on the UPS is connected to the NAS; there's no computer in the rack to run the software.
Definitely. I just wanted something rack mountable to allow my NAS to shut down gracefully, and this fits the bill without spending a fortune. Where I used to live we had a lot of momentary and short-term power outages. In this house, not so much.
When I saw this driver for HE and the ability to use the NUT server on the NAS, I figured it would be good for the hubs to shutdown cleanly as well.
I'm just going to put a zwave outlet on the UPS and pair it to my alarm system. That will allow me to remotely shut down the UPS if it ever becomes necessary. When I have some spare time, I'm also going to look into using a spare rPi to run the NUT server on.
Just a thought - does the UPS have an EPO connection? Because if so, maybe you could put a zooz multirelay (or similar) on that, and tell the UPS to drop the power immediately.
Of course without testing I couldn't say if the UPS would come back online on reversing that relay, which would make this a less useful idea!
Nice. Lets get some Qolsys zwave outlet support in the driver... j/k
I'd be on that in a heartbeat if the interface supported it. Unfortunately, all they expose is the alarm devices.
No idea what that even is, but it's a $200 UPS. A great value esp for a rack mounted form factor, but definitely not an enterprise level device. It does support the network add-in module but I'm not sure how much benefit I'd get from that since the UPS is powering the only network I have.
The only real problem here is that short window where the power could come back on before the UPS dies but the HE hubs have already shut down. May never happen again but if it does, it surely will be when we're away for the summer, so I'm glad it happened now so I can be prepared to handle it.
It's an "Emergency power off" connector, which will tell it to drop power (eg from a fire suppression system). You're right it's maybe unlikely on a $200 UPS but given its a rackmount format I thought there might be a chance. Oh, you did give the UPS model further back - no I don't see one in the manual.
It's got a dry contact on the serial connector. The docs are a little light on detail. I think you have to discover it via poking around in the software.
I'd get the card. It can shut down the Nas and the ups.
I still don't understand what that would get me. The NAS shuts down when the UPS battery gets low. Not physically, but it goes into some sort of safe mode where a power interruption won't corrupt anything. When power is restored, it returns to normal mode. If the power goes completely out, the NAS just boots up normally when power is restored. Protecting the NAS is what I bought the UPS for, and it works fine in that regard.
The problem is with the HE hubs, which won't restart without a complete power interruption. A proper NUT server would take care of that automatically, and a zwave outlet powering the entire network rack would take care of it manually. I'll probably do both.
You think a proper NUT server would work better controlling the UPS through that card, as opposed to the USB interface? If that's the case, then maybe it would be worth it.
NUT can integrate with the card via snmp. The card can act like NUT and shut down supported hosts. It can turn off the UPS which you might not want to do from a host that is attached to it.
So again, you may gain with the card the ability to toggle the outlets off after shutdown of the hosts to prevent the issue of a hub that is shut down before the UPS runs out the battery. You gain the ability to power all your hosts off and power down the UPS with reserve power until the utility power comes back and starts it all back up.
Interesting, but reading the manual for the card it says that certain things may not be supported on all models, and most of the other features I really don't need. I think I'd end up going down yet another rabbit hole and I already have way too many unfinished projects around here.
I think the simplest thing to do is to use a zwave plug to control the power to the UPS. I'll probably never need to use it, but it will solve this particular problem if it ever arises again, albeit in an inelegant way.
I will probably also replace my old Dell switch with a Ubiquity POE switch, which I could then use to power two of my hubs. My primary C8-Pro is already on POE, but I have no more free ports on my UDM-Pro SE. So overall a new switch would probably be a better place to spend the money.
The Ups or the device?
This is how I power my hubs. Unifi poe. One of the reasons I have a larger UPS. Network, cameras, hubs, security.
The UPS. If I need to reset anything remotely, I can just power down the UPS for 15 minutes or so until the battery dies. A brute force approach that probably will never be necessary, but better than driving 1000 miles back home to power cycle a device if I completely lose control over something.
I've got 4 Ubiquity POE cameras, 3 HE hubs, a Dell 24-port switch, Synology NAS, UDM Pro-SE and a cable modem on the UPS and it all will run for around 15 minutes on battery power. I really don't care too much about keeping things running longer; during an extended outage Comcast usually goes down anyhow. A bigger UPS would keep the cameras recording longer, but we're not in an area where I'm particularly concerned about security, and the alarm system will run for about 2 days on its own battery.
