PE R720 Enclosure (Backplane) shows Degraded but no information why

I have a PowerEdge R720 and the Backplane (Encloser) show as Degraded (Non-Critical), but that is the only information that I get. Connector 0 show as degraded and  Connector 1 is healthy. All the physical and virtual disk are healthy and the batteries are fine. Has anyone seen something similar and how was it resolved?

I would suggest updating the backplane, as well as the Raid controller. You can find the backplane update here -

That is the controller you have installed?

Hi Chris,

Thanks for the reply. One follow up question, would not having these updates cause the backplane to show as degraded?

Yes it can. If the controller gets too far out of date it will actually start listing the array as degraded, without a drive being failed.
