After purchasing the CyberPower CP1500PFCLCD UPS, I opted to purchase the RCCARD100 so that I could manage the UPS on the network. Unfortunately, the card did not work in the CP1500PFCLCD UPS. There were no lights at all while inserted, and no lights when an ethernet cable was plugged in from a switch.
After digging further online, I didn’t find much about troubleshooting. But I did see lots of people talking about how this management card was cloud-only and required a subscription. I didn’t waste any time and returned it.
I’ll keep the UPS for now, the next UPS will be an Eaton or APC with a real management card. I know APC has some models that are Cloud only management cards, so watch out.
