9124 Password Recovery

Unanswered Question
Apr 20th, 2010

Hi There. I am trying to reset the password on Cisco 9124 that came back from a partner. They haven't provided any of the config information. I am able to get a serial connection running, but I am unable to get a break sequence to work. I have used hypertermincal, minicom, putty, and others. None of them seem to work. No matter where I send the break sequence during the boot up, it doesn't work. Can anyone provide any insight for this?

I have followed the instructions provided on the Cisco site. The only thing that I haven't done is remove the supervisor engine, but I have stand alone switch and I wouldn't know how to do that. The only components that I can remove are the GBICs and the PSs.



I have this problem too.

Hi Matt,

sometimes it's hard to find the correct break combination to boot into single user mode. For me it took some time to find it on a Swedish keyboard layout as the Cisco documentation only says ctrl+].

To verify correct break character run telnet in a MS DOS window. A  correct break would break the session and produce a message like  "Welcome to Microsoft Telnet client...".So you could just test all possible keyboard combinations until you have the right one. Then just follow the correct password recovery procedure:


You need to get to the switch(boot)# prompt to reset password. Press ctrl+] exactly when you see "Loading system software". The message "Switching to runlevel: 1" indicates you are entering switch(boot)# prompt.
