InfraStruXure Power Generation System 5
Overview
InfraStruXure Power Generation System
The InfraStruXure Power Generation System consists of a diesel-powered generator and a Smart
Distribution Panel with Automatic Transfer Switch (ATS). The ATS is connected to both the utility
(Source 1) and the generator (Source 2), with the utility as the preferred source. The ATS can
alternatively be connected to a second utility. The ATS is designed for installation on the data center
floor, which places power distribution closer to your data center equipment. Labels provide a quick
visual indication of which ATS sub-feed breaker is supplying power to each piece of equipment. The
diagram below provides examples of data center equipment that can be connected to the ATS.
