Hello, I just upgraded a PowerConnect 6248 from 3.3.5.5 to 3.3.7.2 and captured the stack trace of a panic over the serial console. I have now reverted back to 3.3.5.5 and would like to submit the stack trace. Email support is not available for me.  Where should I send it? Thanks!
Where can I submit a PowerConnect 6248 panic?
