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 SCSI bus and
the logical arrays. 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 the power supply is functioning normally. It will change to
amber if one of the power supplies in a dual power supply system should fail or is turned
off. If only one power supply is installed, the Power Supply Status LED and PSU Fault LED
will function normally as if both power supplies are installed.
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 their respective disk drive slot. There are
12 Drive Status and 12 Drive Activity LEDs, one group for each disk drive. Refer to “Drive
LEDs” on page 45 for detailed information.
Audible Alarm
An audible alarm will sound when any of the enclosure’s component status changes to an
abnormal state. To silence the alarm, press the Alarm Reset button located on the front
bezel. The corresponding alarm’s LED will remain illuminated until the condition returns
to a normal state.
