SOLVED Will this UPS work? APC Back-UPS BE850M2

[canute4444]

I have this APC Back-UPS BE850M2 model connected to my TrueNAS server.
It is showing up as Back-UPS ES 850G2 on the Server

Code:

# dmesg | grep ugen
ugen0.1: <0x8086 XHCI root HUB> at usbus0
ugen0.2: <American Power Conversion Back-UPS ES 850G2 FW:931.a10.D USB FW:a10> a
t usbus0

I tried a few different combinations of Driver, Username and Password. But when I start the service, within a few seconds the service seems stop automatically.

I keep seeing ERR ACCESS-DENIED and forced shutdown in progress in the logs

Code:

# tail -40 /var/log/messages

The UPS information seems accurate too

What settings should I be using?

Try Monitor User = upsmon and Monitor Password = fixmepass. My APC uses the same driver, and that seems to be the expected combination, but I don't remember where I got that. Good luck!

That worked. Thank you
