We are experiencing for the third time a a problem at 4506 with RJ module. What happens is that at some moment ports stop working progressively from last to first ports until the entire module stops working. This happend at different equipment and with different IOS versions but all of them were 4506 with WS-X4248-RJ45V module.We tested and even connecting a notebook directly to the por it doesn't show not even eletrical signal (led off).
PS: Available power is more than 60% of total. Attached I'm placing a show tech of one of sitches.
