wanted to implement something like that with my 1920R UPS for my rack but haven’t found the time to commit to antiquated hardware.
Was enough of a hassle dealing with the expired SSL certs on the management card yet getting software running on one of my machines to communicate with the UPS.
Honestly you should just bypass dells management software and use NUT. It supports your UPS’s management card if you enable SNMP or you can bypass it all together and just run off of the USB/serial.
All things considered my two servers chilling chew around 60w on average, not taking into account my POE cameras or other devices. The UPS should run for over a day without getting close to draining its batteries (have a half populated ebm too).
I’m pretty surprised I can run my whole network for an hour off of my 1500va UPS with three switches and a handful of POE devices. I’m still thinking about replacing it with a rack mount unit so i can lock it inside my rack as I’ve been having issues with unauthorized people messing with it.
