File Download Information
File name Min. Memory
(MB) Min. Flash
(MB) Date Released
c6k222-ps-mz.122-18.SXD7b.bin 256 64 13-DEC-2006
you need a 64 MB flash and at least 256 MB to be able to load the new image.
Size 26499180 bytes
Another important point I remember is the need for the correct bootloader on the MSFC2 flash.
You may need to update the bootloader in order to be able to run the new ios image.
So also the size of the MSFC2 internal flash matters.
I'm looking inside the end of sale products because sup2/MSFC2 are not sold anymore.
The best practice is to keep the main software image in slot0 and the boot loader image in the MSFC bootflash. Verify whether you have enough space available in the slot0 and MSFC bootflash in order to copy the new image from the TFTP server. You can check the size of the new image on the PC to which it is downloaded
