Just got a new IAP-275-US, trying to add it into a VC cluster with IAP-205-US's, I manually updated the firmware on the 275 to match the 205's (6.5.4.4). When the IAP booted up, it'd consistently elect itself as a new master, so I added these two lines at the apboot prompt:
iap_controller_less 1
iap_master 0
Now the 275 boots & tries to join the VC cluster, but it fails, the VC shows: AP register fail because of regulatory domain mismatch & the 'show log system' is giving me: AP regulatory domains don't match Master-0, slave-200, reason-4
Am I missing something obvious on this? Thanks for the help/advice!
