2 single green blinks
Configuration from USB stick successfully completed.

4 single red blinks
Factory setting restore started.
NOTE: During the restoring factory settings procedure on RK2x RM2x DM2x routers, the LED continues to flash alternatively red and green. At the end of the procedure, a sequence of red blinks indicate an error during the restoring process.
5 single red blinks
The Runtime execution error: a system restart will follow.
6 single red blinks
The USB stick data format is not correct or an unknown error occurred.
Remote connection
Steady lighted
It activates when at least one
FTRA Manager
Ubiquity Manager
is connected to the router, otherwise it is deactivated.
COM Rx COM Tx
Status and external commands
These LEDs are directly connected to the Rx/Tx serial port signals that show traffic going through network.
