I honestly don't understand why the passive port is even being mentioned here. It shouldn't have any affect on passing, or not passing MoCA.

Granted, if the power goes out. Then the device that is connected to that port won't see the other devices via MoCA. But at that point, why would you care... The power is out. However, if the client has a backup for power... Then the installer shoulda installed this amp on a backup circuit as well.
