Status Indicator LEDs
The Status Indicator LEDs located above the Alarm Reset button, comprise the
Power-On LED, Channel Status LED, Power Supply Status LED, and Fan Status
LED. The following are descriptions of each of the LEDs.
Power-On LED
The Power-On LED signifies that the enclosure is powered on and will be
illuminated green when power has been applied.
Channel Status LED
The LED will indicate the status of the logical array(s), when a RAID Controller is
installed. It will indicate a failed controller by alternately blinking green and amber
when a failure does occurs. It will change to amber when the system detects a
problem with a logical array.
Power Supply Status
The Power Supply Status LED indicates the condition of the power supplies. The
LED will illuminate steady green when both power supplies are functioning normally
and will change to amber if one of the power supplies should fail or be turned off.
A failed power supply can also be identified by the illumination of the amber “Fault”
LED located on the individual power supply.
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.
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.
