Hi there I consider the need for Telnet backdoor, no longer necessary to obtain root privileges !
According to the NSA310-3 Users Guide manual, in section: Users Guide : 1.1.4 RESET Button (with my amendment in bold):
Press the RESET button until you hear one beep (after about two seconds – while powered on), then release it. You will hear one more beep after you release the button. This resets the NSA’s IP address and password to the default values.
I tried this myself today, while re-branding the TDC HomeDisk to factory settings.
Is this just to update the wiki , when finding these kind of facts ?
I don't get this. What does the possibility to reset the IP and password to do with getting root access?
