Fan Status

Fan Status
The Fan Status LED indicates the condition of the cooling fans. The LED will illuminate
green when both fans are functioning normally and will change to amber if either of the
fans fail. The LED will blink amber if an over temperature condition occurs.
Drive LEDs
The Drive LEDs are located on the left side of the front bezel between the ventilation ribs
and comprise the Drive Status LEDs and Drive Activity LEDs. The Drive LEDs are
grouped in pairs and are in the general location of the disk drive slot.
These Drive LEDs assist with identifying array status, the presence of a drive in a drive slot,
and which drives are experiencing I/O activity. Refer to “LED Matrix” on page 47.
Drive Status LEDs
There are twelve Drive Status LEDs. The Drive Status LED is the left LED of each pair of
Drive LEDs. This LED will illuminate steady green when a drive is present in the slot and
powered on. Refer to “LED Matrix” on page 47 for more details.
Drive Activity LEDs
There are twelve Drive Activity LEDs. These LEDs will flash indicating a specific drive is
being accessed, either during read or write activity. The Drive Activity LED is the right
LED of each pair of Drive LEDs.
Drive Carrier LitePipes
On each disk drive carrier are “LitePipes.” They are located on the lower right side of each
drive carrier. The LitePipes present some of the information provided by the front bezel
Drive LEDs, that is, drive activity information and drive fault (failure) or data rebuilding
notifications when the front bezel is removed.
