3-4 SAS Drive Tray LEDs
Each SAS drive tray has two LEDs:
•
Green: When illuminated, the green LED on the front of the SAS drive tray
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 notified by your system
management software. Please refer to Chapter 6 for instructions on replacing
failed SAS drives.
Power
Indicates power is being supplied to the system's power supply units. This LED
should normally be illuminated when the system is operating.
