A customer purchased a TN2302AP HV3 and claims its compatible with w CM 2.1 . The Board is a "lucent board" made in 01 according to the SN. How would we find out the right board to use the vendor is sending another board to my client but I think he is going to send the same type of board which will be the same result. Yes I have tried to add it manually in change circuits but it still sees no board.
