3-4 Drive Carrier LEDs
The SC946EDJ chassis uses SAS or SATA drives.
SAS3 Drives
Each SAS3 drive carrier has two sets of LEDs, one set of blue and red LED indica-
tors for each drive. The LEDs function as follows:
Each drive carrier has a blue LED. When illuminated in a solid on state, this blue
LED (on the front of the SAS/SATA drive carrier) indicates a SAS drive. A connec-
tion to the SAS/SATA backplane enables this LED to blink on and off when that
particular drive is being accessed.
When the red LED is blinking, it indicates that the system is either building, initial-
izing or rebuilding RAID.
