2924-SFP Lost Password

Any help would be greatly appreciated! Trying to recover a 2924-SFP with a lost password. Tried the console with Ctrl + B and Ctrl + C to no avail. Documentation for the switch simply states for lost password contact 3Com.

Re: 2924-SFP Lost Password

Hi Claude, I had the same problem and just resolve it.

Try this:



From a console connection



Enter the following key sequence (CTRL/SHIFT - (minus)) ONCE at the appropriate time



Baseline 2924

power cycle the switch

When "Testing the System SDRAM........PASS" is seen

CTRL/Shift - (minus)

When "Autoboot in 2 seconds- press Return or Esc" is seen

Press Enter Immediately

At The Startup Menu

Select Password Recovery

Select Back

Re: 2924-SFP Lost Password

Hi,

 

I have 3com 2924 - SFP PLUS on the desk - with forgotten password.

 

I have downloaded PUTTY, set the VT100+ mode with appropriate com port settings.

 

When I connect to the switch and power it on, I can see booting of the switch.

 

I even connect external keyboard to the laptop I am working on to get the switch reset, but still can't do that.

 

CTRL + B

CTRL + C

CTRL + SHIFT + "-"

 

Left control nor right controls button don't make the magic.

 

I am desperate :(

 

Could anybody make any video of sucessfull reset on youtube please?  Or how to proceed with this?

 

 

Please help

 

Thank you

 

Regards

Jakub

Re: 2924-SFP Lost Password

 I have the same issue on the same model, pressed all possible combinations but the boot sequence just continues until the login.

No possibility to interrupt it. :(
