Steve,

To disable auto registration for any of the port set Sid 0 or Sid1 to 0 or empty. This will disable the port and not attempt a registration with CM. If you want to manually add the port in CM, put Sid0 or Sid1 as the mac-address of the appropriate port.

Go to the webpage of the ata device, for instance http://10.1.1.125. From there select the 'SCCP Paramaters' (assuming you are using sccp). Once at the parameters page, set SID1 to 0 and click apply. The event log errors will go away after this.
