7.12.1.4 Disk Drive LEDs

The disk drive LEDs are visible from the front of the system when the left door is open, as shown in the following figure.

When a disk drive LED lights steadily and is green, it indicates that the slot is populated and that the drive is receiving power. When an LED is green and flashing, it indicates that there is activity on the disk. Some applications use the LED to indicate a fault on the disk drive. In this case, the LED changes color to yellow and lights steadily. The disk drive LEDs retain their state when the system is powered off. A yellow indicator also results in the yellow general fault indicator being lit on the system front panel.
