When the voltage drops below a certain point, it will let you know about it. Nearly every UPS supports the notion of detecting the low battery all by itself. upsmon doesn’t consider a UPS to be critical until it’s both on battery and low battery at the same time. Why doesn’t upsmon shut down my system? I pulled the plug and nothing happened. Assuming you have a good reason for it (see the next entry), then look at scheduling.txt or the upssched(8) man page for some ideas.Ģ3. You probably don’t want to do this, since it doesn’t maximize your runtime on battery. How can I make upsmon shut down my system after some fixed interval? (I should probably copy it here, just to be a complete reply)Ģ2. This is a fairly reasonable default, if that is what it does.Īnyway, I'd appreciate any clarification! Which is it? because 10% remaining battery is significantly higher than 120s remaining. Will it initiate shutdown at 120s remaining then? OR, is it instead based on the runtime value? I am guessing that is expressed in seconds (based on what is displayed in the status page widget).
If I run a "upsc" command from the shell I get this: # upsc APC_SUA750ĭoes this mean that by default it will start sending out warning messages at the 50% battery level (presumably to console) and will initiate shutdown at 10% left? So, can anyone speak to what the default behavior is? I've read some of the NUT documentation, but I couldn't quite figure it out from that. etc.) but I don't see any of this in NUT. In APCUPSd I needed to edit the config file in order to specify all sorts of behaviors, like what triggers a shutdown (percent battery left, estimated battery time left, etc.
#Smart serial:cable nut serial#
I suspect that this is not a NUT implementation issue, but rather the serial I/O chip on my board and pfSense don't necessarily get along.Īnyway, it's working, but I'm not quite sure what it's doing in its default configuration. I had hoped to get it to work using the proprietary"Smart" APC serial cable, as I have greater faith in serial connection stability than I do USB, but in the end I just couldn't get that to work.
#Smart serial:cable nut series#
Works beautifully on my APC Smart UPS SUA750, which I actually wasn't sure it would, because the SmartUPS series has a red/single star rating on the NUT webpage. The Control Center does not list the UPS or allow any configuration as I was expecting.Just saw that NUT was made available in 2.3 the other day, and installed it the other night. The file ups.conf has been modified to have an entry similar to the following: I then click the "Finish" button and a message box pops up saying "Write support for users is incomplete It lacks some support for some extra fields that would be lost else". Selecting any of the ports returns the message saying "The wizard successfully configured the new "Smart-UPS|APC" "ups" "1" UPS device."
#Smart serial:cable nut manual#
The Control Center does not auto detect it and using the manual options by selecting the option: I was hoping to set up the UPS in PCLOS via the GUI in the PCLOS Control Center -> Hardware -> Set up a UPS for power monitoring. This adapter uses the FTDI FT232R bridge chip. I have an APC Smart-UPS 700 with serial port connected to my Supermicro C7X58 motherboard USB connector via an FTDI US232R-10 USB to RS232 adapter cable.
