When deploying a project ,we usually forget the console password, making it difficult to access the device .
Situation 1: Forget the console password ,but telnet is working .
Solution: telnet the device and change the console password
[USG2200] user-interface console 0
[USG2200-ui-console0] authentication-mode local user admin password cipher admin
Save the configuration finally.
Situation 2: Forget the console password ,and telnet password.
Solution:step1:reboot the device
Step2 :press “Ctrl+B” when you see “Press Ctrl+B to Enter Boot Menu...” and input password “O&m15213” to enter bootrom menu (NOTE: the passsord here may change with version ,it is advised to check refer the product document if this password is not working )
Step3: press ”ctrl+z” to enter hidden menu ,select “Recover Console Password”.
Step4: exit and reboot
Step5: Connect cable to console port to test .
Situation 3:Console password, telnet password and bootrom password all were forgotten.
On this situation , we don’t have any way to restore the password, please apply a sparepart if possible
Password is very important and easily be forgotten , please save it and don’t try to change the default bootrom password .
