    545545Issue:
    546  * A resistor that sinks the backfeed current when POE is plugged in was at 10k and was too little of resistance. This was allowing the POE leakage current to charge up the WAD pin and eventually turning off the PoE.
    547 
    548 Resolution:
    549  * Replace the 10k resistor R198 with a 60.4k resistor
     546 * The PoE controllers wall adapter sense resistor, used for disabling the PoE input when the barrel jack input is used, is not rated properly which could lead to a lower MTBF on this resistor when the barrel jack input is used with voltages above 30V DC.
     547
     548Resolution:
     549 * It is recommended to not use voltage over 30VDC when using the barrel jack input to power the board or to only power the board using PoE.
