Hi all, we are installing a new office location with 2x stacks of X450Gs, so 16 switches total. Each has 2x 715W PSUs. Since installation a month ago we have had 10 PSU failures. This seems unusually high (we have two other similarly sized offices open for 2+ years with no PSU failures...) Has anyone else had any notable PSU failures recently? Could there be a bad batch in circulation? We are also having specialist electricians study the building electrics. We are due to have staff move into the building at the beginning of January...
