Hi

I've just installed a triple setup of BE25's and am generally pleased with the setup.
 

The only thing thats bafflling me is the network app is intermittently showing message "The ethernet backhaul speed is low. Please check your ethernet cable connection". There doesn't appear to be any performance issue, though havent carried out any stress testing as yet.

All cables are CAT7 cables. 

On the switch I can see a blue (2.5gb) light for the incoming from the main device, and 1gb for the others. 

Can someone please advise. Is this a known bug? Should i be concerned? even 1gb should be sufficient to make this warning go away?
