Great, well thanks for the help! All of the buttons that should be lit up are lit up from what I can tell. I will pull the ccu and see if I can find the other end of these lines purely out of curiosity now. My octopus lights up fine, so these lines must be unplugged from it if they are part of the fiber optic system. I'll let you know what I find after I do a little more digging.
