			In Gen 1 units, the SD card is locked. The password can be captured by dumping the flash memory of the unit, or by intercepting the communication to the SD card itself during boot.

			In Gen 2 units, the SD card is not locked, as in its contents can be freely read and written.

			An SD card can also be used to update the firmware in the unit.
