I'm updating the firmware on several different model of ICX switches that I have, but I'm running into a bit of confusion. For the ICX7650-48p, the recommended firmware is the 08.0.95g ufi version, but the zip file contains both a TNR08095gufi.bin and a TNS08095gufi.bin file. I can't find anything in the release notes that specifies a difference between these two versions. Is there a difference? What situations would call for either version being applied over the other?
