Chapter 4 - Managing and Monitoring
Fan Status
45
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. These LEDs will flash
to indicate disk I/O activity.
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.
