Configuration register is 0xF

Hi All,

 

I have a C2960S switch where the config reg value is 0xF. This switch is rebooting frequently. 

 

Can anybody tell me about this?

No crashinfo folder present in the flash and "sh version" shows the switch is having power problems.  

Check the power feed or power outlet where the appliance is drawing power from.

Thank you for the info !
