Password reset
Password recovery method to reset the admin password.
- .Use a console cable to connect to the CLI, and enter username “recover” and password “recover” to place your unit in password recovery mode. The unit will remain in password recovery mode for a maximum of 30 seconds, before it returns to the CLI login prompt.
- . During the 30 seconds, perform a hard reset on the unit while it is still in password recovery mode by switching it off (pulling the power on it), waiting a few seconds, and switching it on again.
- . When the unit has rebooted following the hard reset enter a new password for the “admin” user account.
- . Enter enable to leave password recovery enabled, or enter disable to turn it off. You are now logged in as the default “admin” user. WARNING: If you enter disable here, you will not be able to perform password recovery again! I have not figured out a way to get around this… It is best to leave it enabled!
Factory reset
Reset Factory Defaults
Use admin login (not manager). Use procedure above if you have lost the admin username. The manager username does not have as much access rights to perform the steps below.
Once logged into the CLI, use command: gettingStarted – this will allow you to set IP address, amongst a couple other minor things. Follow prompts, and apply settings, reboot. Done.
For full factory reset/defaults, issue command: system, control, initialize. Then type Yes to proceed.
