https://community.hpe.com/t5/disk-enclosures/msa1000-power-supply-question/m-p/3889091#M22101 I'm wondering if the MSA controllers are connected to the power supplies directly. If one power supply fails does that bring down the path to one controller? I thought that they were completely independent (as long as one power supply is functioning both controllers will function) but I'm seeing some behavior that might indicate otherwise.<BR /><BR />Thanks,<BR />Colin Mon, 30 Oct 2006 10:37:33 GMT ColinF 2006-10-30T10:37:33Z https://community.hpe.com/t5/disk-enclosures/msa1000-power-supply-question/m-p/3889091#M22101 I'm wondering if the MSA controllers are connected to the power supplies directly.
