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.
