I am replacing an existing system with a BCM450. Trying to use the existing DN range but the application DN range falls smack in the middle. Tried to reconfigure but it does not work. If you have an application range of 300-399 and try to reconfigure to a range of 100 DN's starting at 400, and ending at 499 it makes the application range 300-499. Also tried to do a cold reset to default the application DN range. That didn't work either. Any help would be appreciated.
