DISK LED x 4
There are 2 LEDs for each disk slot. The left LED indicates “Connection” and the
right one indicates “Health/Access”.
The Connection LED is only one-color (white). When the hard disk is connected,
the white LED will be on. The Connection LED also indicates hard disk power
status and disk rebuild status. When the target disk is being rebuilt, the white
LED will blink.
The Health/Access LED is dual-color (red/blue). The red color is for Health
condition. The blue color is for Access condition. When the hard disk is not
healthy, the red LED will be on. When the hard disk is being accessed, the blue
LED will flash. When hard disk is healthy and not being accessed, no LED color
will be on.

The difference between a flashing LED and a blinking LED is that flashing
refers to the read/write activity and blinking refers to slow but regular pulses.
Please see “LEDs: Red” under Q&As section for more information.
SAFE REMOVAL OF THE RAID SYSTEM
Safe removal of the RAID System from the host controller is highly
recommended, especially when switching interfaces. In order to safely remove
the RAID System from the host controller, one would need to eject the device on
the actual host controller system.
