APC Network cards turn your UPS into a very dynamic unit. The AP9618 card incorporates all the basic network, environmental and relay control features, but adds a Out Of Band Management feature.
In other words, this card (qsc18p) allows you to monitor and manage the UPS by remote control regardless of whether the UPS is powered on. Also called Lights Out Management, this adds a powerful feature to units.
The qsc18 is available in our store along with the basic (qsc17), relay (qsc19), environmental (qsc19p), and 2nd generation card (qsc30). Since it still serves an important purpose, APC still makes it, even while they have discontinued its cousins.
