I suspect the LSI card does not play nice with the SGPIO sideband controller, and I decided to replace the chassis with one similar to my SC846 chassis, where the LSI card and drive bay LED&rsquo;s do work fine.</p> <p>What should have been a simple replacement turned into quite a recovery operation.</p>
