Disk module indicators (AIC RAID controller)

You must remove the front bezel assembly to see these LEDs. Each disk module has LEDs that indicate status. The LEDs are located on the disk backplane. The following table explains the status conditions indicated by the different LED behaviors. If two or more status conditions occur simultaneously, the LED displays the behavior for the highest priority condition. Priority number 1 is the highest priority.

Use the Device Manager on your computer to identify the RAID controller:

  1. From the Start menu, type:
    Device Manager
    The Device Manager window displays.

  2. Select Disk drives to expand and view the drive information. AIC displays and identifies the RAID controller as AIC.
  3. Close Device Manager.
