Disk drive carrier module LEDs
Disk drive status is monitored by a green LED and an amber LED mounted on the front of each drive carrier module, as shown in the
following gure.
The drive module LEDs are identied in the gure, and the LED behavior is described in the table following the gure.
• In normal operation, the green LED are on, and icker as the drive operates.
• In normal operation the amber LED will be:
– O if there is no drive present.
– O as the drive operates.
– On if there is a drive fault.
