Hot Swap Hard Drive Indicators

Each of the hot swap hard drives has two LED indicators:
•
Status Indicator
This LED indicates the drive operating condition: normal, warning, or failure.
•
Activity Indicator
This LED indicates the disk drive access activity. This LED indicator is controlled by the
disk drive directly. When a drive is accessed, the LED indicator shows a green light.
Table 1-2 and Table 1-3 describe the LED signals used to indicate the operation status of a
disk drive.
