HDD LED x 4

There are 2 LEDs for each HDD slot. The left LED indicates "Connection" and
the right one indicates "Health/Access".
The Connection LED is only one-color (white). When the HDD is connected, the
white LED will be on. The Connection LED also indicates HDD power status and
disk rebuild status. When the target HDD 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 HDD is not healthy,
the red LED will be on. When the HDD is being accessed, the blue LED will flash.
When HDD is healthy and not being accessed, no LED color will be on.
