Release Image
Note: Starting from 10.5(3)F, Cisco NX-OS no longer provides a separate EPLD image. Instead, the EPLD image is bundled with all NX-OS images and so the image sizes are correspondingly larger.

● The 64-bit Cisco NX-OS image filename with “nxos64-s1-dpu” as the prefix (for example, nxos64-s1-dpu.10.5.3s.F.bin) is supported and it is mandatory on N9324C Smart Switches.
Note: The 32-bit image is no longer supported.
