Red: The SES2 compliant backplane activates the red LED to indicate a drive failure. If one of the SAS drives fail, you should be notified by your system management software. Please refer to Chapter 6 for instructions on replacing failed SAS drives.
SATA Drives (6015B-T)
Each SATA drive carrier has two LEDs.
Green: When illuminated, the green LED on the front of the SATA drive car- rier 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 two states. When blinking, it indicates the drive is rebuilding. When solid, it indicates a drive failure. If a SATA drive fails, you should be notified by your system management software. Please refer to Chapter 6 for instructions on replacing failed SATA drives.
