So, I actually got this figured out. I have an APC UPS. Apparently, it doesn't have a network jack, as I thought, it only has a "SmartConnect" port (RJ45) that allows it to be monitored remotely. Which is stupid, but whatever. The battery is a 5 year old Lead Acid battery in need of replacement, so I bought a new UPS (APC Smart-UPS 3000VA Lithium Ion UPS, SMTL3000RMUCNC) ... and this one has a Network controller in it, so monitoring with NUT should work now. FWIW, once I figured out SmartConnect wasn't a "normal" port, I was able to get the cloud service configured very quickly and easily. My UPS showed quickly (a few hours) and I was able to remotely update it's firmware. -- Thanks, Alexander Sent from my Google Pixel 7 Pro On Wed, Aug 28, 2024, 14:30 Arun Khan via PLUG-discuss < plug-discuss@lists.phxlinux.org> wrote: > > > On Thu, Aug 15, 2024 at 4:51 PM Snyder, Alexander J via PLUG-discuss < > plug-discuss@lists.phxlinux.org> wrote: > >> Does anyone in this community have any experience managing Network UPS? >> >> I purchased an "APC 3000VA Smart-UPS" ( >> https://www.amazon.com/gp/product/B0785NCFMY) in 2020.
