Back to Basics: Using Hot Swap to Minimize Downtime

Back to Basics: Using Hot Swap to Minimize Downtime

Given the critical role of modern telecommunications and data communications equipment, maximizing its online availability must always be the first priority. Clearly, any equipment’s availability depends critically on that of its power supply. Fortunately, close to zero power system downtime can be effectively achieved by combining two techniques – redundancy and hot-swapping. In this back-to-basics post we will see how these work together, and how systems can be designed for hot swapping. Consider for example a rack-mounted telecommunications system comprising modules plugged into the rack’s backplane, with a total power requirement of 120 W...
