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? The Powerware Environmental Rack Monitor (ERM) continuously monitors environmental conditions at the rack level, providing an extra level of security for critical assets. The primary application is for high-density data centers, but this compact, full-featured device can monitor conditions in laboratories, hospitals, warehouses, libraries, museums, and any other indoor location where the environment must be maintained within acceptable levels.
