The Nureva® HDX series systems feature status indicator lights on the front and rear of the CM3 hub. 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.
