Disk LEDs
The disk LEDs are visible from the front of the system when the bottom door is
open, as shown in the following figure.
Note – The center support of the disk cage is marked with the slot number for each
disk drive. Starting at the bottom, the disks are numbered from 0 to 19.
When a disk 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 blinking, it
indicates that there is activity on the disk. Some applications may use the LED to
indicate a fault on the disk drive. In this case, the LED changes color to yellow and
remains lit. The disk drive LEDs do not retain their state when the system is
powered off or the keyswitch is turned to the Standby position ( ).
