RoboRio Communication Issues

[The_Waffleing]

So a group of 4 guys including myself have been trying to figure out for the last 2 1/2 hours why our RoboRio isn't wanting to communicate with us. I know for a fact that there's an issue with the communication between the RoboRio and the radio itself because of the fact that our Radio LED is displaying nothing. We've tried several different methods in attempt to fix the communication however to no avail. Our PCM, PDP, RoboRio and the 6 Talons SRXs that are being used on our robot are all up to date with their firmware along with re-imaging the RoboRio 3 times. As of right now, my team is currently stumped and I on behalf of them is reaching out to anyone willing to help us come to a solution to this conundrum. Thanks in advance.
