[Cisco] Which one should I use as the C891FJ-K9 IOS file?


Question: Which IOS should I use?

If you look at the product list on Cisco’s Software Download site, you can see that there are “C891F” and “C891FJ“.

Checking each IOS file, you can see that the file name is as follows.

  • C891F >>>> “c800-universalk9…

  • C891FJ >>>> “c800j-universalk9…

Answer: Either can be used

c800-universalk9…” and “c800j-universalk9…” have different file names, but the contents of the files are exactly the same. So it doesn’t matter which file you use.
