Hi,
I missed that you have already tried reset password BY EMERGENY user.
Then you need to reset by factory default.
When it is impossible to use the management tool due to the loss of the manager username or password,then you need use the Console port to reset the controller to its factory defaults. Process is as follows:
1. Power off the controller.
2. Connect the provided serial cable between the controller Console port and a PC
3. Configure the VT-100 terminal-emulation software (Microsoft Hyperterminal for Windows, or Minicom for Linux) as follows:
• terminal
• Baud rate of 9600
• 8 data bits
• 1 stop bit
• parity: No
• Flow control: No 4. Open an appropriately-configured terminal session.
5. Power on the controller.A system boot message appears.
6. Do not press any keyboard keys. Wait for the LILO prompt to appear. It looks like this:
LILO 22.1 boot:
IMPORTANT:As soon as the LILO prompt appears, press the keyboard space bar to prevent the automatic (non-factory-default) boot from continuing. You must tap the space bar or otherkey within four seconds of the prompt appearing.
7. At the LILO prompt, enter the command
linux factory
and press Enter. The controller restarts with factory defaults settings.Resetting to factory defaults.
