NUT package (2.8.0 and below)

newberger

Hi - I have a Cyberpower OR700, which I previously had on my pfSense system using USB. I added the RMCARD205 and am now trying to connect to NUT via SNMP. My initial setup in the NUT menu only specifies the UPS IP (set static in the pfSense DHCP) UPS Type (Remote SNMP) and UPS name.

pfSense/NUT does see the UPS and reports the status, but the amount of data is much less than when I connected via USB.

I am using SNMPv1, although the UPS has SNMPv3 available. I'm not sure if that would make any difference?

@newberger A quick google search for "NUT RMCARD205" finds this in the NUT issues list: Support CyberPower RMCARD205

@dennypage, thanks. I googled many topics around NUT SNMP setup, but not that specific query on this card. In reading it, it appears that more information is available if the ‘private’ SNMP community is used, but I can’t tell if it’s working correctly. Also, I had seen other RMCARDs are supported and was unsure how compatible this card would be with that support. Are you saying this card isn’t going to work yet?

You'll have to read through the NUT issue to understand what currently works and what will work better after direct support is added.

The issue seems pretty active, and they appear to be looking for help... nudge.

@dennypage Thanks - I'll follow the thread and help out, if possible.

Hi everyone, sorry my first post here is an ask for help but.. well I need some help!
I have a slightly older APC Back-UPS 1500 RS UPS connect via a USB cable and have managed to get the basics of NUT working as a server (on pfSense) to shutdown itself as well as a remote FreeNAS and Ubuntu machine.

My problem is that when power is restored, as soon as the host that talks to the UPS starts to boot up (i.e. immediately after going through POST) it triggers the UPS to go on battery (despite being plugged into the wall with AC power on) which it then stays on until the battery dies. Clearly this is not great for any machine attached that started at the same time as the firewall came up so trying to resolve this for a clean startup. If I leave the system to do it's thing it will sit there cycling; power up, trigger UPS to go on battery, continue booting, battery dies, abrupt shutdown, power up, rinse and repeat.

I've just moved the UPS from my rack to my study to do some more testing and I'm experiencing the same behaviour running the NUT master on a ubuntu test machine.. seems unlikely now it's anything specific to the pfSense iteration.

I'm hoping someone with experience configuring NUT and UPS's here might know what the issue since it seems like either a driver config option I've not set or something to do with startup / shutdown / init scrips etc that is a whole other kettle of fish to get my head around! In desperation I installed the windows utility (on a windows machine) to see if there were any behaviour options I could set on the UPS but there was nothing.

Again, apologies this isn't really a pfSense specific issue (other than ultimately I want the UPS managed by it). Alternatively if anyone could just give me the keywords to search on google for the behaviour I'm trying to stop that would be a great start!

Thanks,
Dave

Edit: Just tried apcupsd which I think works as I would expect so I guess I have a partial workaround but will need to see if I can get that to notify NUT on FreeNAS.. but that's definitely outside the scope of this forum!

@uk_dave A few questions:

Are you using running the current version of pfSense (2.4.5)?
Are you using the current version of the nut package (2.7.4_7)?
Do you have anything in Advanced Settings? In particular, any of these?
- ignorelb
- override.battery.charge.warning
- override.battery.charge.low
- override.battery.runtime.low

uk_dave

@dennypage Thanks for replying,

Running 2.4.5-RELEASE-p1 (amd64) of pfSense and 2.7.4_7 of the NUT package.

I'm currently doing this testing on a fresh install of pfSense, all I had added to the config was:

USB Type: Local USB
UPS Name: ups
Driver: usbhid
ups.users: [remoteuser]
password = upsmon
upsmon slave

Here's my UPS: BR1500GI

I have disabled the master / slave behaviour of the UPS so all 5x sockets on the battery backup side should be in the 'Battery backup outlets with surge protection only' mode. I was assuming that NUT tells the UPS to shutdown and therefore having 5x sockets I can use rather than 3x was preferable.

Thanks,
Dave

I don't see anything troubling in your upsrw or upsc output.

@uk_dave said in NUT package:

My problem is that when power is restored, as soon as the host that talks to the UPS starts to boot up (i.e. immediately after going through POST) it triggers the UPS to go on battery (despite being plugged into the wall with AC power on) which it then stays on until the battery dies.

More questions:

Are you testing by pulling mains from the UPS? Assuming yes...
When the pfSense shutdown occurs, is the UPS turning off the output?
How long are you waiting before restoring mains to the UPS?

uk_dave

@dennypage

yes, I turn the mains socket off
I don't believe it is, I've got a halogen lamp on a dimmer that can pull up to 435W so I've varied the load to full to bring the estimated run time down to 1 min remaining to force the shutdown process then ease up so it can last a few minutes and the UPS doesn't shut down until the battery dies... definitely longer than 20s
I usually wait about a minute before restoring power.

dennypage

@uk_dave said in NUT package:

I don't believe it is

Okay, this definitely is a problem. The last thing nut does is instruct the UPS to remove power after the configurable delay (20s by default).

What I would do next is to move the pfSense box to not be powered by the UPS, but still have the USB connected. Then, test the power kill command of the UPS using "upsdrvctl shutdown" or the -k option to usbhid-ups.

@dennypage can you help with the correct config pls.
I have a APC UPS master on TrueNAS box

I have a dumb UPS connected to pfsense and need to shutdown pfsense based on a timer triggered by the master due to the non-shared UPS.

I have looked at the NUT documentation and examples below but i can't figure out if i need to use the heartbeat config or not.

http://rogerprice.org/NUT/ConfigExamples.A5.pdf
https://wiki.ipfire.org/addons/nut/detailed

i simply want to shutdown the slave 20min after power loss, but obviously cancel the timer if the power comes back.

is the a way to simulate a power failure on the master to test the slave without actually cutting power to the master?

uk_dave

@dennypage
Hi, I have pfSense plugged into the wall and connected to the UPS via USB.

running 'upsdrvctl shutdown' does indeed turn off the outputs, 20s later shutdowns the UPS which then turns back on since AC is still active to the UPS. Watching the console of pfSense it goes through:

Initiating UPS shutdown
UPS ups on battery
UPS ups on line power

I wondered if somehow it had automagically fixed itself so after booting up again (successfully) I pulled the power to the UPS. pfSense shutdown correctly but the UPS outputs are still active and being powered. Left it for about 5 minutes but the UPS did not shutdown.

This behaviour is consistent using NUT over 3x different machines and 2x different USB cables (bought another for testing). The machines I've been testing on (each as a standalone master) are:

HP T730 thin client (currently using as a test pfSense environment)
Asus Chromebox running Ubuntu
Supermicro pfSense machine based around a X11SCL-IF

Two common denominators... the UPS and me, one of them is doing something wrong I think :)
Cheers

Very weird. It seems like the the shutdown command is being ignored if the UPS is on battery. It sounds like a firmware bug, but you said that apcupsd worked correctly. I'm afraid I'm out of ideas. You might approach folk on the NUT mailing list and see what they might have to offer.

uk_dave

@dennypage

Thanks for all your help anyway. I've sent an email to the NUT mailing list so see if anyone has any ideas.
Cheers

any of you guys can help me with the correct config for upssched and upsmon? Do i need the heartbeat for what i want to do?

Look for FSD in the NUT documentation.

A dumb UPS isn't something supported by the NUT pfSense package. In general dumb USPs are not a good idea because there is nothing that will trigger the restart of the system when power returns.
