I have 2 Cisco Nexus 5596UP that are running on 5.2(1)N1(4) version. They had new IOS n5000-uk9.5.2.1.N1.9a.bin and it's n5000-uk9-kickstart.5.2.1.N1.9a.bin pre-staged to come up on during a reload. The reload caused them to crash with no console output what so ever. any ideas as to what could have caused this. It was not a significant jump in IOS versions. Thanks
