The System Status Light

For All Edgeports except the Edgeport/1
Red This light signifies a loss of USB communication with the host. If the loss is due to unplugging the unit, when it
is reconnected the light will blink red a few moments before turning green. Otherwise, the light indicates a problem
with the drivers, which may need to be reinstalled. The red light will also blink during installation until the
installation is complete.
Amber This light signifies serial port activity on the Edgeport. The amber light may also flash briefly during
installation.
Green This light indicates the serial ports are successfully set up and the Edgeport is operating normally.
