If both memory spaces are taken up with customer-specific standard settings and a rollout configuration, then the device cannot be reset to the LANCOM factory settings by using the reset button. If it becomes impossible to access the configuration (e.g. in case of a lost password), then the LANCOM factory settings can only by restored by means of the serial interface.
The serial interface can be used to load firmware into the device. Entering the serial number instead of the configuration password results in the device configuration being reset to its ex-factory settings. In this way you can regain access to the device if it becomes impossible to restore the LANCOM factory settings in any other way.
- Use the serial configuration cable to connect the device to a computer.
- On the computer, start a terminal program such as Hyperterminal.
- Open a connection with the settings 115200bps, 8n1, hardware handshake (RTS/CTS).
- In the terminal program's welcome screen, press the Return key until the request to enter the password appears.
- Enter the serial number that is displayed under the firmware version and press Return again.
- The device now expects a firmware upload. You initiate this in Hyperterminal by clicking onTransfer/ Send file and selecting X-Modem as the transfer protocol.
Note: Uploading the firmware in this way completely deletes the configuration,
including the boot configuration, and returns the device to its ex-factory
settings! This deletes all of the files stored on the device, including
any rollout certificates. For this reason you should only use this option
if you have no other way of accessing the device. The configuration and
boot configuration are deleted even if the firmware upload is interrupted.
