Somehow one of my chassis&rsquo; started to think, that the power redundancy was lost.</p> <figure> <img loading="lazy" src="https://christian.blog.pakiheim.de/uploads/2012/08/ucs-6.png" width="500"/> </figure> <p>After looking at it a bit deeper, it seems only the GUI or the chassis did notice this power glitch:</p> <figure> <img loading="lazy" src="https://christian.blog.pakiheim.de/uploads/2012/08/ucs-5.png" width="500"/> </figure> <p>As you can see, all PSU&rsquo;s still have power.
