What happens when the Exterior 400IP non-resettable power hours counter reaches maximum?

The Exterior 400IP (and similar units of the same era/firmware type like the Exterior 200) NON RESETTABLE POWER HOURS counter will count to a maximum of 65535 hours.

Once it reaches this maximum it will then 'rollover' back to 1 hour (there is no zero hour) with no errors or issues.

This can also explain why the total non-resettable hours can show a LOWER value than the resettable hours counter.

65535 hours is approx 7.48 years of constant power.
