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 SAS/SATA drive carrier has a green LED. When illumi-
nated, this green LED (on the front of the SAS/SATA 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 notied by your system management software.
