Dell Force10 S4820T password
I'm looking for help.
I bought a Dell Force10 S4820T switch at an auction. It boots up fine, but it has a password I don't recognize. I see it has an old firmware version, FTOS 8.3.19.0. I've searched several websites to find out how to remove the password. I've seen several, but they all mention a higher FTOS version, 9 or 10. Because of this, I can't remove the password. Is there any way to help me with this? I'm not a company. I'm just a regular citizen interested in the switch.

Hello,
Can you see if these commands are available on the menu that you see after you type help?
setenv
saveenv
If you see them, you can follow the procedure on page 75 and 76 to recover from forgotten password by using command “setenv stconfigignore true” to ignore the enable password one time:
https://dl.dell.com/manuals/all-products/esuprt_ser_stor_net/esuprt_force10/force10-s4820_reference%20guide2_en-us.pdf
This will allow to login one time without enable password, but you have to create a new password once you are logged in.
If these commands are not present in the menu, can you list the commands you see.

Hi,
You can try this command following the steps in the reference article:
line console 0
no authentication login
no password
exit
copy running-config startup-config

This isn't the solution. I tried what you sent, but even on the first line:line console 0
no authentication login no password exit copy running-config startup-config. it gives an unrecognizable response. I wrote that I have a FTOS 8 version, while what you sent is for FTOS 9 and FTOS 10. For FTOS 8, I see that when I boot up and abort with ESC and then type help, I get a list of commands where these commands don't appear.
