Alcatel_Switch_OS6900-T48C6 || Admin password recover process

Hello Team,

any one know exactly process how to reset Admin password for console only for below model.

OS6900-T48C6 -- if any good documents there please help me out.


Please try the following:

1. reload the switch
2. Hit key to stop autoboot
3. Type the command to reset password to default and reboot :


The OS6900-T/X48 series use the ONIE platform. Thus, the password recovery process is different compared to the rest of the switches.

Step-1: Reboot the switch and break the boot sequence to select 'ONIE'.

Step-2: Select the 'DIAG' option.

Execute the below commands to remove the switch local "user" database and reload.

root@(none):/# cd /mnt/ssd5/system root@(none):/# rm userTable8 root@(none):/# reboot

I’m on a 2260 with a lost password from a work colleague that left.
I was able to reset the password just fine with ‘setAdminPasswordDefault’ but the command ‘boot’ didn’t work. I simply restarted the switch after the reset bit was set but just wondering about the right procedure. This was my log today:
