You should remove the standby module then proceed to the password recovery.

After you reach terminat and reset the password you can SAVE your config (to be 100% SAFE), then use write command, then add the standby module back to work.

Hi teymur,

You never lost your configuration, what you need to do is...

1. Make a complete config synch between active and standby supervisor engine (I hope autosync is already enabled)
2. Write the config to NVRAM on standby supervisor engine.
3. Now when you put back the standby supervisor engine, reload the active supervisor engine whcih take the standby be active and active be standby.

Also I would like to infor the password recovery procedure for you...

Try the below procedure with only one supervisor in the chassis.

1) Connect the console cable to the Supervisor IV console port
2) Reset the 4507 by power cycling the unit.
3) Interrupt the boot sequence by hitting CTRL+C
4) Using the confreg command, I set it to skip the boot-up configuration.
5) I issue the reset command to reboot the 4507 again.
