SAS Drive Carrier LEDs
Each SAS drive carrier has two LEDs.

When illuminated, the green LED on the front of the SAS drive carrier
indicates drive activity. A connection to the SAS SCA backplane enables this LED
to blink on and off when that particular drive is being accessed.
Red:
A SAF-TE compliant backplane is needed to activate the red LEDs,
which indicate a drive failure. Please refer to Chapter 6 for instructions on replacing
failed SAS drives.
