3-4 Drive Carrier LEDs
Your system supports SAS or SATA, but not both at the same time.
SAS/SATA Drives
Each SAS/SATA drive carrier has two LEDs.
•
Green: Each drive carrier has a green LED. When illuminated, this green LED
(on the front of the drive carrier) indicates drive activity. A connection to the
SAS/SATA backplane enables this LED to blink on and off when that particular
drive is being accessed.
•
Red: The red LED indicates a SAS/SATA drive failure. If one of the SAS/SATA
drives fail, you should be notified by your system management software. (Re -
quires software support.)
