I have a client with several 3COM superstack II PS Hub 40's. They have had them for 6+ years and now no one knows the passwords to gain entry to manage them. They have tried all the defaults and every password they have. 3COM won't help because they are out of warranty, and the only thing I could find on their site said to RMA the hub or have a 3COM tech come out. Does anyone know a way to reset these hubs to factory defaults?
