I have a similar problem, the default password was changed by another party. I believe what has to be done is to upgrade the firmware of the card, Follow the procedure "Local PC FTP for ADIX IP SUB". Unfortunately, in my case, the firmware version of the card is the same version of the upgrade I have on hand - so it does not complete upgrade. Although, not 100% certain this will solve the problem, it seems like it should work, if I had a version greater than 2.01. Lately I have been trying to crack the password with a brute force hacking tool lately - no luck there either.
