FEX 2000 AA Mismatch

We installed two nexus 5500 switches with different NXOS . N5K1 has 5.2.1.N1.4.bin and another N5k2 has n5000-uk9.5.1.3.N1.1a.bin. As soon as we connected the Nexus 2000 fex in to it , it gave error :


Error : AA Version Mismatch

101 FEX-TOP-Rack1 AA Version Mismatch N2K-C2248TP-1GE SSI16070L2R
107 FEX-Rack7 Connected N2K-C2248TP-1GE SSI1602034H
Solution :- downgrade 5.2.1.N1.4.bin to n5000-uk9.5.1.3.N1.1a.bin
