As a network interface to a compatible APC UPS, though, it does its job and does it quite well.

It is similar price to some stand-alone monitoring products that you may want to check out if you need more than APC offers, or don't have a management capable APC device.

Bought a used model for an APC Smart-UPS ATX 500 Power Supply SMT750RM2U. Card initially configured itself using DHCP, then I changed it to static IP through the browser UI

We bought this add-in card for our APC Smart-UPS SMX1500RM2U X 1200W/1500VA LCD 120V 2U/Tower UPS System

Note: Unless you pair this with a compatible APC UPS, it is absolutely a one-star product.
