There was a recent hardware change to the Motorola AP5131 and AP300 which requires a specific version of software to operate properly. In the little information I’ve been able to dig up Motorola makes reference to a “Isotope HW” change. Anyone know what the that is?
In any event if you are ordering/deploying any new AP5131 or AP300s you’ll need to be mindful of this change and ensure that you are running the appropriate software releases and/or you have applied the specific patches.
You can find the release notes concerning the AP5131 right here.
