Device Status LEDs

The LED states shown in the following table are determined through user-configurable threshold values for the Cell LED Amber / Green light, and modem enabled / disabled information.

Status LEDs
LED Condition
	LED Off	Amber Flashing	Amber Solid	Green Flashing	Green solid
Power	Device is off.		On a dual power supply system: Only one PSU is connected.		On a single power supply system: The power is connected. On a dual power supply system: Redundant power is connected.
Heartbeat	Device has halted.	Device is booting.		Normal operation.	Device is halted.
Network	No active network connection	Device is failover starting.	Device is in failover.	Normal network connection is stopping, or normal network is up and failover is stopping.	Network is connected.
Cellular Interface	Cellular is not in use.	Cell is starting and signal is below threshold. The LED signal threshold config is set to 50%.	Cell is connected and signal is below threshold. The LED signal threshold is set to 50%.	The cell is starting and signal is above, or equal to the threshold.	Cell is connected. and signal is above, or equal to the threshold.
IOIO				Any serial activity is received, on either console/usb console or device serial ports.
OM Devices Cloud / Internet	LSP is disabled and there are no existing Lighthouse enrollments.	LSP is currently running on the device.	An error occurred while running LSP.	The device can reach the lighthouse instance and is attempting to enroll. If a lighthouse is unreachable the LED will not start.	The device is enrolled and connected to a lighthouse. There will be a short delay between the UI status reported and the LED changing to solid green.
