Cisco 2960X POE Switch- No Power on Switch

I have a Cisco 2960X PoE Switch, But there is an issue with Power on few ports. When I executed "show power inline" command. Oper status is "off" for all ports. Any solution would be apperciated.

 

Thanks

Just want to checkl, is there any reboot on this switch recently, can show post show version.

otehr sugggestion is to take ay PoE device, like IPPhone, connected to directly to switch and test it.

when you connected PoE device make sure you take show power inline output and post here.

Hello Mubasshir,

 

We have quite a few 2960X models and I noticed that some ports are loosing their POE capabilities. some random POE based AP  have lost power. I tried them on different ports they worked. just bad ports I guess...
