Linux: Configure and Control APC SmartUPS During a Power Failure

Posted on in Categories , last updated November 18, 2012

My Linux nas server connected to APC SmartUPS using usb cable and I would like to detect a power failure. If power is not restored my server must shutdown when the battery is exhausted. How do I configure and use my APC SmartUPS under Debina / Ubuntu / RHEL / CentOS / Fedora / Scientific Linux operating system for power management?
