Disk Activity LEDs
The eight Disk Activity LEDs on the front of the cabinet indicate activity, such as reads or
writes, on each of the installed drives. For the rack-mount cabinet, the Disk Activity LEDs
are the upper set of LEDs. For the tower-based cabinet the Disk Activity LEDs are the set on
the right side.
When the InterRAID-8e cabinet door is closed, you cannot view the individual Disk Activity
LEDs on the installed drives. Therefore, the cabinet door has a corresponding Disk Activity
LED for each installed disk drive to allow you to view the activity of each drive with the
cabinet door closed. Refer to the disk drive manufacturer’s specifications for information
pertaining to the Disk Activity LED.
Drive Status LEDs
The eight Drive Status LEDs on the front of the cabinet indicates the status of each of the
installed drives. For the rack-mount cabinet, the Disk Status LEDs are the lower set of
LEDs. For the tower-based cabinet the Disk Status LEDs are the set on the left side. The
following table shows the status indications for disk drives in an InterRAID-8e cabinet
attached to a MegaRAID controller.
