How to reset 2916SFP+ password

Hi. I have a 2916+ baseline switch. I have lost admin password. I tried to enter in failsafe mode via serial connection, but i'm not able to give "ctrl+c" command. I have tried with windows hyperterminal (ctrl+break), with teraterm (alt+b), with putty but with no success.

How can i do?

Thanks to all.

F.

Testing the System SDRAM........PASS

In the terminal connection settins you must check linux keyboard.

Not VT100 as in manual.

I had the same problem with a 2924 SFP Plus.



My solution:



- hit "CTRL / Shift - (minus)" ONCE

- hit ENTER shortly before "Autoboot in 2 seconds" appears
