Thông thường khi bạn muốn nâng cấp os version của các thiết bị Nexus lên phiên bản cao hơn đồng nghĩa bạn phải upgrade luôn BIOS của nó. Ví dụ như Nxos version 7 thì BIOS bạn cần cũng phải ở phiên bản 4.0 trở lên.
Bây giờ mình sẽ demo upgrade thiết bị Nexus 3064 có BIOS version 1.7.0 lên 2.6.0 như sau. Trước tiên hãy check version thiết bị trước khi upgrade.

Sau khi khởi động xong bạn hãy login vào thiết bị và show boot nó lên, nếu cài đặt boot đang trống thì hãy thực hiện bước dưới. Trường hợp của mình cài đặt boot đang được cài đặt nên mình sẽ bỏ qua bước dưới.
