When the controller powers on, the boot firmware checks the SD card for a text file that indicates how it should handle the image on the SD card. Ideally your integrator should create the memory image on the SD card with the "Load on Corrupt Memory" feature selected, or the "Load Always" feature selected.
If they created it with "Load on User Command" feature selected, then you would need Studio 5000 Logix Designer software to go online and issue that command.
I'm not sure why they are flying you an SD card if you have an Internet connection. You could use an SD imaging utility and e-mail or a file drop service. I'm not 100% sure you couldn't just use Windows file transfer and format the card for FAT16.
I wish RA made it easy to put a file directly onto an SD card, but they just don't. You have to compile the program by downloading it to the correct model of controller, and make what is essentially a whole disk image.
