NOTE:

The Boot ROM stores the Bootstrap for booting the router.

The memory is used to store the communication data between the system and the CPU when the system
is running.

The CF card is used to store the software system and configuration file. The CF card LED blinks when the
system is reading/writing data from/to the CF card. In this case, do not remove the CF card, otherwise
hardware and software damage may occur.

Do not unplug the USB device during USB data transmission; otherwise, data loss or even hardware
failures may occur.

The USB interface does not support hot-swapping of USB modems from Sierra Wireless.
