SATA Drive Carrier LEDs
Each Serial ATA drive carrier has two LEDs.

When illuminated, the green LED on the front of the SATA drive car-
rier indicates drive activity. A connection to the SATA backplane enables this LED
to blink on and off when that particular drive is being accessed.
Red: The red LED indicates two states. When blinking, it indicates the drive
is rebuilding. When solid, it indicates a drive failure. If a SATA drive fails, you
should be notifi ed by your system management software. Please refer to Chapter
6 for instructions on replacing failed SATA drives.
