Drive Carrier LEDs
The SC811 chassis uses SAS/SATA or SCSI drives, but not both.
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 to indicate an SAS/SATA drive failure. If one of the SAS/
SATA drives fail, you should be notified by your system management software.
SCSI Drives
Each SCSI drive carrier has two LEDs.
•
Green: When illuminated, the green LED on the front of the SCSI drive carrier
indicates drive activity. A connection to the SCSI backplane enables this LED
to blink on and off when that particular drive is being accessed.
•
Red: The SAF-TE compliant backplane activates the red LED to indicate a drive
failure. If one of the SCSI drives fail, you should be notified by your system
management software.
