Appendix C: Bulk Configuration or Firmware Upgrade via DHCP/TFTP455 config.txt devices.csvNote: Supported syntax of "fwupdate.cfg" and "config.txt" may varybased on different firmware versions. If you have existingconfiguration files, it is suggested to double check with RaritanTechnical Support for the correctness of these files prior to using thisfeature.2. Configure your TFTP server properly. See TFTP Requirements (onpage 455).3. Copy ALL required configuration files into the TFTP root directory. Ifthe tasks you will perform include firmware upgrade, an appropriatefirmware binary file is also required.4. Properly configure your DHCP server so that it refers to the file"fwupdate.cfg" on the TFTP server for your EMX.Click one or more of the following links for detailed DHCPconfiguration instructions, based on your system and the IP addresstype. DHCP IPv4 Configuration in Windows (on page 456) DHCP IPv6 Configuration in Windows (on page 466) DHCP IPv4 Configuration in Linux (on page 473) DHCP IPv6 Configuration in Linux (on page 475)5. Make sure all of the desired EMX devices use DHCP as the IPconfiguration method and have been directly connected to thenetwork.6. Re-boot these EMX devices. The DHCP server will execute thecommands in the "fwupdate.cfg" file on the TFTP server to configureor upgrade those EMX devices supporting DHCP in the samenetwork.DHCP will execute the "fwupdate.cfg" commands once for IPv4 andonce for IPv6 respectively if both IPv4 and IPv6 settings areconfigured properly in DHCP.TFTP RequirementsTo perform bulk configuration or firmware upgrade successfully, yourTFTP server must meet the following requirements: The server is able to work with both IPv4 and IPv6.In Linux, remove any IPv4 or IPv6 flags from /etc/xinetd.d/tftp.Note: DHCP will execute the "fwupdate.cfg" commands once forIPv4 and once for IPv6 respectively if both IPv4 and IPv6 settingsare configured properly in DHCP.
