Please read Script Templates section in Lighthouse manual http://ftp.opengear.com/download/manual/current/ and the following article as it explains Script Templates usage, how to upload and apply to specific nodes.
Note: Use the freely available Notepad++ which allows you to save the script with Unix (LF) line endings, not DOS (CRLF) line endings. Ensure any 'single' and "double" quotation marks have not been converted into curly “smart quotes”. Applying scripts with DOS (CRLF) line endings will break node configuration.
