Okay, because the 17F software is labeled for 112-port, and the single-backplane FXT is 112 ports, I tried loading the 17F software. The key let me do it, and it loaded up okay. I've seen in other cases, where the port count was wrong (e.g., trying to put 480 software on a system with 2 backplanes), the key would reject the software.

So, now I'm wondering: does anyone know if this version is actually compatable with the FXT, or if I need to go back to the last version listed on the CCC under FXT: 17D (the earlier of the two versions of 17D).

The reason I'm asking is because of the new problems I've picked up on an FXT, referenced in this thread .

Thanks, in advance, for the input.

Any system that will take 17A will take 17F as that was a maintenance update not a level update.

What's the difference between the 112 and 480 port versions, then. Keying?

True, I found a 17F version for 96 (labeled as 112) and for 480 (since they are for FXII), but what would I be able to do if I had a FXT 224 or 464? If you go back and look at the software for FXS/FXT, it was different for 112, 224, and 464.
