Status Indicator LEDs
The Status Indicator LEDs comprise the Power-On LED, Channel Status LED, Power
Supply Status LED, and Fan Status LED. These series of LEDs are grouped on the right
side of the front bezel directly above the Alarm Reset button. The following is a description
of each of these 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 Channel Status LED will illuminate green to indicate a valid status of the FC loop or a
logical array. Should an error occur, the LED will change to amber.
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 supply should fail or is turned off.
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 any of the fans
fail.
Drive LEDs
The Drive LEDs are located on the left side of the front bezel in 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. There are 12 Drive
Status and 12 Drive Activity LEDs, one group for each disk drive.
