I verified the current NX-OS software of the Nexus 5K switch to be 7.3(1)N1(1) using the show version command.

There's an upgrade path to follow per the Cisco Nexus 7.3(8)N1(1) Release Notes: 7.3(1) > 7.3(2) > 7.3(8). The said code release also list down the supported hardware such as the Nexus switch platforms, line card modules and Fabric Extenders (FEX).
So I upgraded first to 7.3(2)N1(1) and downloaded the main NX-OS and Kickstart image (BIOS).
I deleted some old image files to give space in bootflash using the delete command. It's best practice to keep the previous image in case you need to roll back or downgrade.
