Dean,
I am sorry I forgot to reply to your email yesterday. So the RSA key is not used to do initial setup. It is used during the re-key process based on the documentation. After you cleared the process try setting the re-key interval to a really low denominator and wait for the re-key period. You should see a failure in the re-key event without the RSA KEY.
