One of DroboPro's many benefits is a series of lights that tell you
everything you need to know, without your having to launch any
application software on your computer. Remember, DroboPro is
designed to actively monitor and protect your data at all times.
DroboPro will automatically take any necessary actions and display
them using the following lights:
Drive Lights
Power Light
Activity Light
Capacity Gauge

Solid Yellow: Add a drive or replace the current drive
with a larger drive soon. DroboPro is running out of
disk space.
Blinking Yellow and Green: Do not remove these
drives or power down. DroboPro is working to
protect your data.
Solid Red: Add a drive or replace the current drive
with a larger drive immediately. DroboPro is critically
low on space.
Blinking Red: Replace this drive immediately. This
drive has failed and needs to be replaced.
