 +====== LED Behavior ======
 +
 +The front and rear LEDs indicate drive status and activity (only the 2big and 5big have rear drive LEDs). This section describes the behavior of the LED indicators.
 +
 +<note tech>​**Technical note:** Even if you have turned off the front LED using the Dashboard, events triggering a red light will always cause the front LED to turn on.</​note>​
