CHAPTER 2
Elements on A850
25
All three LEDs are on while the device is in reset state or booting
the (Linux) operating system kernel.
The PWR and RUN LEDs are on and the USR LED is off while the
A850 is initialized (the CF card is checked, the configuration is
loaded and various services are started).
The activity LED flashes for 0.1 seconds if there is an RTU com-
mand sent or if the answer is received.
The “Error mode” LED pattern is used if there is a serious hard-
ware error (unable to read CF card).
The “No configuration mode” LED pattern is used as factory
default (as long as there is no root password configured and no
basic network configuration given).
The “Battery low power” LED pattern is used while shutting down
the Gateway due to low battery.
