Test-Fail Status on N2000 series switch

Hello,

I have had these switches in place for several months now.  We have VOIP phones that the switches provide power to and today there were reports of phones with no power.  After troubleshooting the problem, it looks like most of the ports do not provide power.   Here is the output of show power inline.  Noticed total power is 0 watts and the status on all of the switch ports are Test-Fail. I only copied the first 11 ports but all 48 are all the same.  I have verified that some of these ports do provide power but majority do not.  Any suggestions?

There were no changes made to this switch prior to this issue.  The current firmware of the switch is 6.1.0.6.  

Thanks for any assistance anyone can give me.
