Alarm System
All major components (except the fan module) include a local alarm LED.
Fan failure is indicated by the Fan A and Fan B Alarm LEDs on the
MX-34000 Matrix board. (For more information about these and other
LEDs, see
The master alarm indicator is an LED on the front panel (Power/Alarm)
where green indicates normal operation and red indicates an alarm condi-
tion.
The rear panel Alarm BNC operates according to SMPTE standard
269M-1999. When an alarm is asserted, the circuit that is associated with the
Alarm connector will present low impedance to a customer-provided
external current source. See
for an example of a rear panel master
alarm circuit (left) and an example of a customer-supplied indicator circuit
(right).
