I use 3750 for 16 PCs and 12 IP Phone 7960G. PC client still work but I can’t use or activate PoE on my IP Phone anymore. I try to give command = “power inline consumption <miliwatts range 4000 – 15400>” but still failed.
does anyone know whats the problem??

This is a hardware problem. I have fixed a few switches with that problem WS-C3760-48PS-S and WS-C3560-48PS-S. Check my services auction on eBay. Item number 320264282221.
