You may own an earlier firmware revision on your 8166A. While the 8166A is booting it checks automatically compliance of firmware and modules installed. In case of non-compliance you will be notified to update the firmware.

To make the 8166A compliant with newer modules by updating the firmware, you do not need to return them to Keysight Technologies.
