         Blinking Yellow and Green: Do not remove these drives or power down. Your Drobo device is working to protect your data.

Power Light

 

         Green: The power is on and your Drobo device is ready.

         Yellow: Your Drobo device is in the process of powering on.

         Red: Your Drobo device has overheated. Safely power down your Drobo device, disconnect the data cable and then the power cable. Let it cool down and then restart.

Activity Light

         Blinking Green: Data is actively being transferred between your computer and your Drobo device. Do not remove or add drives during this process.

Capacity Gauge

         Blue: Displays the percentage of your Drobo device that is full, in 10% increments. There are 10 capacity gauge lights. So, for example, if your Drobo device is 30% full, three blue lights display.
