The green LED indicates a Floppy Read or Write operation has been done. No green light at all, or a solid green light, indicates a problem. Please contact SFA Support if you are seeing this on your floppy drive emulator.
The red LED indicates that the USB stick is inserted. The red LED should flicker when the USB is inserted. If you don’t have a red light or if the red LED stays solid there is a problem. This is another time in which you should contact SFA Support.
