If one of it had a switching code, you can do a 'boot system flash primary/secondary' to load the image. In this case, you need to load the switching code first and use the above to boot from the partition.
Your command on that platform is: copy tftp system-manifest 10.1.2.3 FI08080e_Manifest.txt primary switch-image
Download and extract 08080e, but do not worry about all the different platforms it supports... You want all 664 MB of it in a folder. In my case it is c:\TFTP-Root\08080e
Under there are folders like c:\TFTP-Root\08080e\ICX7150, ICX7250, ICX7450, etc.
I personally use Tftpd64 by Ph. Jounin, but there are many great TFTP programs available such as the one from Solar Winds. In my case, I point the "Current Directory" to c:\TFTP-Root\08080e\ in my TFTP program.
On the switch, set an IP on an interface or VE on the same subnet you are on. If you do it correctly, you should be able to ping your computer "ping 10.1.2.3" for example.
This command below assumes your computer is 10.1.2.3
By historical convention, we send the switching firmware to the primary and routing firmware to the secondary on all Fast-Iron type devices. Before upgrading one switching firmware version to another, I would backup "copy" the primary => secondary.
Likewise, if I were running routing firmware, I would boot the secondary. If I were going to upgrade, I would backup secondary => primary
Here is the command to upgrade the Routing firmware (for reference): copy tftp system-manifest 10.1.2.3 FI08080e_Manifest.txt secondary router-image
When done the "show flash" will show:
Stack unit 1:
NAND Type: Micron NAND 2GiB (x 1)
Compressed Pri Code size = 25973456, Version:08.0.80eT211 (SPS08080e.bin)
