3-4 Drive Carrier LEDs
Your chassis uses SAS or SATA, but not both at the same time.
SAS/SATA Drives
Each SAS/SATA drive carrier has two LEDs.
Green or Blue:
•
Each hard disk drive carrier has either a green or a blue LED,
depending upon the hard disk drives and backplane used. When illuminated,
this LED 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 a SAS/SATA drive failure. If one of the SAS/SATA
drives fail, you should be notified by your system management software.
