4-4 Drive Carrier LEDs
Each hard drive carrier has two LEDs.
Blue:
When illuminated, this blue LED (on the front of the 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 red LED to indicate a drive failure. If one of the hard drives fails, replace
it with a compatible enterprise-level hard drive model.
