48V is out of range (47.0V)

Hey Guys,

I've been getting this error message in the logs on one of my switches. Is this something I should be worried about, or do something? What does this actually mean?

I have a WS-12-250-AC which has been giving this exact message for years now but it hasn't given us any trouble. I'm not actually sure how long its been showing this error, but the switch is probably 5 or 6 years old at this point. PoE load is about 50 - 60 watts. This particular switch is indoors and the fan is still working too.
