The Channel Mode LED indicates the status of the
array subsystem by changes in its color and state.
When illuminated steady green, the LED indicates
normal array activities.
When the LED changes to amber (flashing or steady) it
indicates abnormal activities, for more information see
LED Descriptions described later in this guide.

The Power Supply Status LED indicates the condition
of the power supplies by changes in its color. The LED
will illuminate steady green when all the power
supplies are functioning normally and will change to
amber if one of the power supplies should fail. The LED
will also switch to amber if the power system is in a
non-redundant state. A failed component can be
identified via the Operator Control Panel and the lack
of a “DC Good” LED located on each power supply unit.

The Fan Status LED indicates the condition of the
cooling fans by changes in its color. The LED will
illuminate green when all of the fans are functioning
normally and will change to amber if any of the fans
should fail.
When a failed component is present, use the Operator
Control Panel to identify the failed fan, see Hardware
Menu described later in this guide. The fans are
identified on the rear door panel via placarded
markings.
Alarm Speaker
An audible alarm will sound when any component’s
condition changes to an abnormal state. The Status
Indicator LEDs will provide a general area of failure by
the LED condition (color and/or state), and the failed
component can then be identified using the Operator
Control Panel.
To silence the alarm, access the control panel and
select “Turn Off Alarm”, see Main Menu described later
in this guide.
