Router Module MKII: LEDs & Switches
The Router Module MKII (980/33) provides the following front panel connections, LEDs and switches:
ACTIVE LED Flashes green when the control system is booted and running.
The ACTIVE LED on each Nova73 module, or DALLIS card,
should blink in time with all other ACTIVE LEDs (at 1Hz). This
shows that the card is synchronous to the rest of the system. If
an LED is out of sync, then check that the card is fitted
correctly, and if the symptom persists, replace the card.
STANDBY LED Illuminates in yellow if the module is in standby.
If you have a main and redundant Router Module fitted to the
Nova73, then one module will be ACTIVE while the other is in
STANDBY .
CHARGE LED Illuminates when the backup power unit is charging.
Off = unit is fully charged.
ALARM LED Illuminates in red when the global alarm is active.
SYNC LEDs These four LEDs indicate the system's sync source :
Flashing green = current sync reference.
Solid green = available redundant sync reference.
