Customer has three B179s, and after running for about 24 hours they will start freezing at random intervals. This doesn’t happen right at the 24-hour mark but generally starts happening around then. The B179s will become completely unresponsive and appear to be working until you try to use one of them. We have swapped out everything except the control unit, which is my next step, but I am doubtful this will fix the issue. So I wanted to see if anyone else has experienced this issue. I’ve tried using power bricks instead of PoE from the switch and PoE was shut off on the ports they were connected to while the power bricks were in place. We have taken out a new B179 which did the same thing. I’ve recently replaced the Avaya switch but this still happens. Any ideas would be greatly appreciated.
