To update the firmware at your SwyxServer you have to perform the following steps related to the installed SwyxWare version:

Open the Server Settings within the SwyxWare Administration and select the tab "SwyxPhone Firmware Update". Within this configuration select the option "Get". Hereby the SwyxServer will contact the Swyx FTP server ( which is configured by default and downloads the latest firmware version.

After this you could validate that the new firmware was download by checking the firmware version information:

If the firmware version (V2 R0.64.0) is listed for all SwyxPhones L6xx you can connect the phones with the new hardware revision without any problems.

If you are not able to download the new firmware because your Swyx Server has currently no connection to Swyx FTP server you should deactivate the automatic Firmware Update temporarily to avoid a downgrade of the phones once they are connected to the Swyx Server. 

Please note that the new firmware version (V2 R0.64.0) can only be used with SwyxWare 2011 and higher versions.
