  • 1.  EX4200 won't boot

    I picked up a used EX4200 recently. The switch powers on and immediately displays a ton of  "DMA Error: status = 80" messages in the console. It never gets further than this error.


    What can I do to troubleshoot and fix?

    Yes, thank you. Turns out the switch still had some warranty left on it. I contacted JTAC and they have issued a RMA.
