Power status and alarm lights
A range of power status and alarm lights are displayed on the front
of the matrix. An alarm reset button (pressed using a pin) is
located above the power status and alarm lights.
Under normal operating conditions, the red alarm lights remain off,
while the green power supply lights stay on continuously.
The status and alarm lights comprise the following:
• Power status light [Power Good]. When lit, this green
status light indicates that the matrix is receiving power from
at least one of the two external 12V power supplies.
• Main alarm light [Alarm]. An alarm source triggers the
red main alarm light and also one of the additional, specific
red alarm lights, allowing you to identify or correct alarm
conditions before they affect the operation of the matrix.
• CPU card alarm light [Config Alarm]. When lit, this red
alarm light indicates a CPU card failure. An audible alarm is
given simultaneously.
• External alarm light [Ext Alarm]. When lit, the red
external alarm light indicates that an external alarm
condition is present.
