Drive Carrier LEDs
Each SAS drive carrier has two LEDs.
Blue: When illuminated, this blue LED (on the front of the drive carrier) indicates
drive activity. A connection to the SAS backplane enables this LED to blink on
and off when that particular drive is being accessed.
Red: The red LED to indicate a drive failure. If one of the SAS drives fails, you
should be referring to your system management software.
