We all know what can happen to the data when power goes off, don't we? We, of course have UPS set and ready, but it's only sufficient for some amount of time depending on the UPS battery capacity. Finally, the UPS will get depleted and, bang, no power - data loss etc. If we can't afford for a backup generator, larger or few more batteries we have to simply switch off as much as we can before draining battery to 0%. Almost all modern UPS have COM, USB or RJ45 connectors to connect to the PC/Server to monitor the condition of UPS and or battery. Most of them can shut down the computer (assuming your computer shut down is not taking 30minutes:)) but what if you have few computers and other data-sensitive equipment such as NAS?
