Anyone get this "warning" in 3300 maintenance log?

[300Blackout]

I keep getting this periodic warning on new 3300 MXE with 7.1 software. 3300 only has one power supply.

Maintenance 2453 Warning 2015/Jun/24 20:04:55 REDUNDANT Power supply 1 installed.

Yes logged it with Mitel, they never seemed have been able to answer it. Design said they were sure the issue was with the power supply but I swapped it out and still got the error.
I Let the ticket lapse in the end as it was getting no where and wasnt causing the customer any issues.

I see it once in a while as well. Doesn't seem to be hurting anything so I just let it go.
