3com 4200g lost bootrom password

[OCDtech]

Hi,

I have a 4200g and I am trying to reset it to factory defaults.  During startup, I push Ctrl+B when prompted, however it asks for a password.  Is there any way to bypass this or reset it somehow?

thanks for your time,

The password wouldn't be:

login: admin

password: (let it blank)

Hi,

I have a bad issue on 4200g 3COM switch, I can't telnet (either port com or IP) to the switch when still have access via web. I tried user : admin and the password I used before which I didn't change. This issue began when I changed the default doamin.

pls any help !
