I’ve had customers lock themselves out of their system by loosing both the IP and Menu password. Since by default, the serial port is also protected by a password, the device becomes completely locked and standard factory default doesn’t reset passwords.

Reset Password on C/EX-Series Endpoint
Step 1: Connect a serial cable to the system at 38400, 8, N, 1
Step 2: Reboot the system (power cycle it)
Step 3: Once Endpoint boot up, log in with the user "PWREC".
Please note that this user is only available a short period of time after reboots. Logging in with this user will reset the password of the root user.
If newer version of software is in used on C-series Endpoint then you will be ask "DO YOU REALLY WANT TO PERFORM A FACTORY RESET? [Y/N]".
Execute "Y" to precede factory reset that will reset admin password as well (changed the password reset approach for security reason).

Thank you. that is a great thing to know... but as I said. What do you do if the serial port is also locked by a password. remember that by default, even the serial port requires a login. If you lose both menu and IP password... and the serial port is set by default with a request for login.... Is there anything you can do or do you have to go with an RMA at this point?

Hi Tomonori,
Currently I have a C60 with TC7.3.7.01c84fd, I don't have admin password for GUI, root.
I need to get access to GUI.
IF I apply pwrec command, all the config will be delete or just admin password?
regards

It's not possible to just reset the admin password, you have to perform a factory reset of the endpoint, note the root account is disabled starting with TC7.1 and replaced with a "remotesupport" account that must be enabled by contacting TAC. You can do a factory reset via RS232, the process is outlined in thread password-recovery. The "pwrec" user is only available when running TC6 and earlier software, TC7 and later software uses a "factoryreset" user.

Factory reset: OK
Based on your comment ,because of the version the codec was not set to factoryreset
eventhough the log show Factory reset:Ok.?
I have not still reset the equipment, but I want to be sure if the config remains.
regards

If you do a factory reset it should clear out the configuration completely as if the endpoint was never installed/configured.
Because you're running TC7.x software, try the "factoryreset" user.

after the reload I noticed the codec was send to factory default eventhough I applied just pwrec command

PWREC is special user account to reset password/factory reset the Endpoint.
This process doesn’t use any of user configured password (no password will be asked while login as PWREC).
