UPS for FreeNas

[Robert Smith]

Is there something I can query with the shop before I buy it?

Querying it with FreeNAS would be the best. LOL

If it is not a known good UPS, then it may require experimentation.

To work properly FreeNAS only cares about two signals: ONBATT and ONLINE.

You connect the UPS via serial port, make sure the right COM port is configured, and try the serial drivers one at a time (there are fewer serial drivers, that is why this process makes sense with serial interface in particular). Pull the UPS power plug from the wall, and observe the FreeNAS console, which should let you know that the UPS went on battery power. Then plug the UPS back, and observe the console for a message that UPS in now ONLINE. If it does not work, try the next driver.

Once you find the working driver, post here so other people do not have to go through the same process with the same UPS model.

If you do not have time for all this, then pick one of the known compatible UPS models.

I have a questions about what UPS you guys are using with your PFC PSU's? any real concerns with compatibility because I'm running into statements that some people say that you need to run a pure sine wave UPS in order for it to run correctly? or just get something that's gonna power my server for 3 minutes while it powers down correctly. I was looking at this unit ( I'm using a seasonic 550w psu)

Seems to be in the compatibility list for freenas ups devices

Thanks!

It is up to the computer power supply. In common new power supply designs, which try to suck as much power from the utilities with least amount of waste, simulated sine wave causes more stress on a particular capacitor used in the system. If the power supply manufacturer chose this capacitor with large enough safety margin, then the power supply will work on the simulated wave just fine. On the other hand, if the least expensive capacitor, just powerful enough for normal pure sine wave operation, was used, then there will be trouble.

To be on the safe side, just get a pure sine wave UPS.

I found some that start at 133 usd. Hopefully they will be listed as compatible. Thanks

I'm using an APC Smart UPS. The Smart line is sine wave. It saved my ass a lot of times. Mine is an old unit, so it only features a Serial port. I discovered that the best NUT implementation for an APC Smart unit is by pfSense and not by FreeNAS.

I was wondering if anyone has used a Eaton 5S1500LCD UPS and has any comments on it. I think it is listed on the networkupstools.org website as compatible hardware, but not sure if i should go in for a APC backup-UPS BR1500G, which I believe is also on the list, but only listed as Back-UPS Pro USB.

The reason for my query is the "support level legend" (green vs orange) in the third column under hardware compatibility. Does this mean that those having a green support level (Eaton 5S1500LCD UPS) are better and hence more compatible (drivers etc...} with FreeNAS?.

APC's website states that it is a stepped approximation to a sine wave???

Thanks.

I too have an older APC Smart UPS. It has a serial port as well as a Network card. I think the model is something like RM3000U3 or something like that. So does FreeNAS have a built in driver for this non USB model?

Also, I have a whole house diesel generator that comes on automatically within 60 seconds of loosing power. Can the FreeNAS plugin be configured to delay shutdown to only begin if power does not return within a set number of minutes?
