DISK ACCESS Lamp ( )

The DISK ACCESS lamp indicates the status of the hard disk mounted in the 3.5-inch disk bay.
The lamp turns green each time access is made to the hard disk.
When the DISK ACCESS lamp turns amber, it indicates that a hard disk failure has occurred.
Check the hard disk lamp for the status of the failing hard disk.
IMPORTANT: If a hard disk in the server is connected to the internal
disk array controller (which is additionally mounted), the access lamp
signal cable (connected to the connector on the mother board) must be
connected from the disk array controller to the mother board.
