WS-C3750-48P poe issue

Hi Guys,

 

 I would like to ask if you have encountered this kind of problem. I have a WS-C3750-48P, all ports were supplying power to ip phones then suddenly only 15 ports can generate POE. Please see details below.

2.  Very old IOS.  

 

My recommendation is to use IOS 12.2(55)SE9.
