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.

1. Uptime of >2 years? Not good.
2. Very old IOS.
My recommendation is to use IOS 12.2(55)SE9.
