Hello, 

 First things that come to mind is that they aren't compatible cables or you are on the passive controller.

Don,

Thanks for the reply. I have tried all 4 SFP+ ports with no luck. We have Dell OEM SFP+ cables on the way so i should be able to test with those.

Hello, 

FYI:  Only the ports on the active controller will work.  The passive ports will always be down until that controller becomes the active. 

 So unless you did a controller failover you didn't actually test all four ports. 

 Are these twinax cables?   Hopefully, the proper Dell cables will resolve it. 

 Regards, 

Don
