Power: Indicates power is being supplied to the system's power supply units. This LED should normally be illuminated when the system is operating.
3-4 Serial ATA Drive Carrier LEDs
Each Serial ATA 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 notifi ed by your system management software. Please refer to Chapter 6 for instructions on replacing failed SATA drives.
