3-4 Serial ATA Drive Carrier LED
Each Serial ATA drive carrier has a green LED. When illuminated, this green LED
(on the front of the Serial ATA drive carrier) indicates drive activity. A connec-
tion to the Serial ATA backplane enables this LED to blink on and off when that
particular drive is being accessed.
Note: The second LED on the SATA carriers is not used.
