Even in the most secure data centers and equipment closets, power quality can suffer, and environmental conditions can become hazardous for UPS systems and other sensitive components. For example, high-density UPS and power management equipment generates more heat than ever within racks and UPS system enclosures. Heat-related issues cause 60 percent of hardware downtime, by some estimates. Other environmental power quality threats - such as humidity, water leaks, smoke and cabinet intrusion - can be just as devastating. If the UPS rack environment isn't supervised at the equipment level, 24/7, how would you know?
