These indicator lights provide real-time feedback during installation and normal operation, and they can help diagnose configuration, connectivity, and system health issues. **Note**: Indicator LEDs use standard traffic-light color conventions (green, amber, red) to align with Console status reporting. Modulation (solid, pulsing, blinking, flashing) provides additional context for troubleshooting. ![](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/base64-converted-image-1780351951817.png) > [!NOTE] > **Note:** Use our network connectivity tool to diagnose configuration issues. If the network passes the connectivity test and power cycling the device does not help, please contact [Nureva support](https://www.nureva.com/contact-us/support). ## Understanding the front status indicator lights The front indicator panel provides primary system feedback and is visible to users during setup and operation. ### Color and behavior key **Primary colors** - Green: Working and fully optimized - Amber: Working, but needs attention or improvement - Red: Error state; requires action **Light modulation** - Solid: Stable state - Pulsing: Transition or processing (for example, startup or IP assignment) - Flashing: Major error condition - Blinking: System fault; power cycle required ## Power indicator | Indicator LED | Description | | --- | --- | | ![](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/cm2.front.status.lights.explained.power.white_04.24.jpg) | **White – Off**: Hub is powered off. **White – Solid**: Hub is powered on. | ## Audio bar and microphone pod indicators (Ports 1–6) | Indicator LED | Description | | --- | --- | | ![](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/cm2.front.status.lights.explained.port1.green_04.24.jpg) | **Green – Solid**: Audio Block or Mic Pod is connected and running normally. **Green – Pulsing**: Device is physically connected, but firmware is still loading and the device is not yet initialized. **Off**: No Audio Block or Mic Pod connected to this port. | ## USB indicator | Indicator LED | Description | | --- | --- | | ![](https://cdn.document360.io/1ff82979-b9bd-4d03-9c0e-683bae60b79a/Images/Documentation/cm2.front.status.lights.explained.usb.green_04.24.jpg) | **Green – Solid**: USB is connected to an in‑room PC and correctly enumerated as an audio device. **Amber – Solid**: Recovery mode;
