Device Status LEDs
The LED states shown below are determined through infod status and config-server data. The config server holds a configurable threshold value for the Cell LED Amber / Green light, and modem enabled / disabled information.

Power |
Device is off. | On a dual power supply system: Only one PSU is connected. |
On a single power supply system: 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 config is set to 50%. |
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. |
Note: The amber LED signal threshold config is set to 50%.of normal signal strength.
Note: OM1200 series devices do not have a cloud LED, therefore, no LED indication is available for LSP or Lighthouse.
