Nexus 5548 with SFP-10G-LR

I have 2 Nexus 5548 connected by 2 links using SFP-10G-LR Gbics. All the ports are in protocol down state. I`ve already tested the cabling between the DCs - it is monomode and OK. Does anybody knows if it could be a N5K configuration parameter, software relase or something like that?

Nexus 5548 with SFP-10G-LR

Have you tried swapping the positions of the two fibre cores on the fibre fly lead when it is inserted into the two connections on the fibre SPF?
