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 1-3 and Table 1-4 describe the LED signals used to indicate the operation status of a disk drive.
