Lost password

The Password Recovery Procedure enables the user to 
override the current password configuration, and disables 
the need for a password to access the console. 
The password recovery is effective until the device is 
reset. If the password/user name has been forgotten or 
lost, the password must be reconfigured using either the 
CLI commands or via the Embedded Web Interface. 
The Password Recovery Procedure is invoked from the 
Startup menu:
1. Reboot the system either by disconnecting the power 

supply, or enter the command: the following message 
is displayed:

Console #reload

Are you sure you want to reboot the 
system (y/n)[n]? 

2. Enter Y. The device reboots. After the POST, when 

the text “

Autoboot in 2 seconds - press 

RETURN or Esc. to abort and enter prom.

” 

is displayed, press 

<Enter>

. 

The Startup Menu is displayed.

[1] Download software

[2] Erase flash file

[3] Erase flash sectors

[4] Password Recovery Procedure

 within 15 seconds after the bootup process 

from the StartUp menu. If the startup menu option is 
not selected within 15 seconds, the accessibility 
requirements are erased, and the system continues 
to load. The password is defined using the CLI mode. 

4. Enter the CLI configuration mode.

5. Enter the password commands:
