These indicator lights provide real-time feedback during installation and normal operation, and they can help diagnose configuration, connectivity, and system health issues. ## Understanding the front status indicator lights The front indicator panel provides primary system feedback and is visible to users during setup and operation. The Indicator LEDs use standard traffic-light color conventions (green, yellow, red) to align with Console status reporting. Modulation (solid, pulsing, blinking) provides additional context for troubleshooting. ![](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/Front%20status%20white.png) ### Color and behavior key | #### Primary colors | #### Light pattern | | --- | --- | | #### Green - Working and fully optimized. | #### Solid - Stable state | | #### Yellow - Working, but needs attention or improvement. | #### [Blinking](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/Network_A_blink_10_21_26.gif) - System fault; power cycle required - The status light is on for 1 second and then off for 4 seconds. | | #### Red - Error state and requires action. | #### [Pulsing](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/Network_A_pulse_10_21_26.gif) - Transition or processing (for example, startup or IP assignment) - The status light is on for 0.25 seconds then off for 0.1 seconds. | ## Power indicator | Indicator LED | Description | | --- | --- | | ![The HDX system hub has a status light to indicate when the system is powered on.](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/Power.png) | #### Solid System hub is powered on. #### Off System hub is powered off. | ## Audio bar and microphone pod indicators (Ports 1–6) | Indicator LED | Description | | --- | --- | | ![Icon for the HDX device ports on the HDX system hub. There are 6 HDX device connection ports.](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/HDX%20device%20port.png) | #### Green Solid: An audio bar or mic pod is connected to specified HDX device port. Pulsing: An audio bar or mic pod is physically connected to the specified port, but an update is required. #### Yellow Solid: An audio bar or microphone pod is at the maximum temperature and overheating. Power down the system and wait at least 10 minutes before powering up again. #### Red Solid: An HDX component is connected and calibration is required. Blinking: Power cycle is required. If HDX components have switched ports a calibration is recommended. An HDX component could be overheating. #### Off Audio bar or microphone pod is not connected to the specified port. Confirm Ethernet cable connections and power cycle the system hub. | ## USB indicator | Indicator LED | Description | | --- | --- | | ![HDX system hubs feature a USB port with a status light displayed on the front of the system hub.](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/USB%20trident.png) | #### Green Solid: Successful USB connection and recognized as a USB device. #### Yellow Solid: The system requires a device software update and is not available as an audio device. #### Off No USB connection or the device is not recognized by the operating system. | ## Network status indicators (A and B) | Indicator LED | Description | | --- | --- | | ![HDX system hubs feature 2 network ports - ports A and B.
