I tried to boot up a c3750G switch after a long time from my store room. I can see all the lights in the front( not the lights on the ports, but only the system oriented lights in the sides) lit and the switch is kind of in a forzen state.Nothing happens beyond that and the lights remain lit. The console connection also seems to be frozen. I cant break using putty, so that I can get to rommon. Pls help is my 3750G busted? Is there anyway I can retreive my switch?
If its failing POST , you have to replace it. If you don't see anything in the console while booting try different speeds on your terminal emulator maybe someone changed the config register otherwise you will have to replace it.The 3750 as long as you are the original owner and it was registered with cisco at the time of purchase should replace it free of charge. Contact cisco on this.
