4-4 Drive Carrier LEDs
The SCF424 chassis which support hot-swappable 2.5" and 3.5" SAS/SATA drives
include the following LED indicators.
SAS/SATA Drives
Each SAS/SATA drive carrier has two LEDs.
•
Blue: Each Serial ATA drive carrier has a blue LED. When illuminated, this blue
LED (on the front of the SATA drive carrier) 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 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
This chassis does not support SCSI drives.
