4-4 Drive Carrier LEDs
Your chassis uses SAS/SATA drives.
SAS/SATA Drives
Each SAS/SATA drive carrier has two LEDs.
Green: Each Serial ATA drive carrier has a green LED. When illuminated, this
green LED (on the front of the SATA drive carrier) indicates drive activity. A con-
nection 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 notiî‚żed by your system management software.
