O FEX N2K-2248TP-E não é suportado nos roteadores Nexus 7000 Series até o NX-OS versão 6.1(1). A correção para esse problema é atualizar para o NX-OS versão 6.1(1) ou posterior. Depois de concluir a atualização, os FEXs estarão on-line.
A terceira tabela na ficha técnica dos extensores de estrutura Cisco Nexus 2000 Series descreve a versão mínima do código necessária para o N2K-2248TP-E.
