There are various ways of carrying out a firmware upload, all of which produce the same result:
- LANconfig
- WEBconfig
- Terminal program
- TFTP
All settings will remain unchanged by a firmware upload. All the same you should save the configuration first for safety's sake (with Device/ Configuration Management / Save to Fileif using LANconfig, for example). Before uploading you should also save a version of the current firmware. If you do not have the firmware as a file, you can download it from www.lancom.de.
If the newly installed release contains parameters which are not present in the device's current firmware, the device will add the missing values using the default settings.
