SAS Drives
Each SAS drive carrier has two LEDs:
Green: When illuminated, the green LED on the front of the SAS drive carrier
indicates drive activity. A connection to the backplane enables this LED to blink on
and off when that particular drive is being accessed.
Red: The SES2 compliant backplane activates the red LED to indicate a
drive failure. If one of the SAS drives fail, you should be notifi ed by your system
management software. Please refer to Chapter 6 for instructions on replacing failed
SAS drives.
