Appendix B: Configuration or Firmware Upgrade with a USB Drive449config.txtTo perform device configuration using a USB drive, you must: Copy the device configuration file "config.txt" to the root directory ofthe USB drive. Reference the "config.txt" file in the config option of the"fwupdate.cfg" file. See fwupdate.cfg (on page 446).The file, config.txt, is a text file containing a number of configuration keysand values to configure or update.This section only introduces the device configuration file in brief, anddoes not document all configuration keys, which vary according to thefirmware version and your EMX model.You can use Raritan's Mass Deployment Utility to create this file byyourself, or contact Raritan to get a device configuration file specific toyour EMX model and firmware version.Regular configuration key syntax: Each configuration key and value pair is in a single line as shownbelow:key=valueNote: Each value in the file must be separated by a single =character, without any surrounding spaces. As of release 3.1.0, multi-line values are supported by using theHere Document Syntax with a user-chosen delimiter.The following illustration declares a value in two lines. You canreplace the delimiter EOF with other delimiter strings.key<value line 1value line 2EOFNote: The line break before the closing EOF is not part of the value.If a line break is required in the value, insert an additional empty linebefore the closing EOF.
