CBS250-16P-2G transformer noise

I just deployed a CBS250-16P-2G in an office environment and the (what I am pretty sure is) transformer noise is pretty bad. Its a continuous high pitched buzz and the users near it are being driven crazy. I am probably going to seek replacement, but I wanted to see what others have experienced with this switch. Do you think I'll have luck with a replacement unit or is this characteristic of the model?

 

FYI, the PoE workload is minimal.  Total consumption is 10 watts across 3 PoE ports.
