Power Status LED
The switch can operate with one or two DC power sources. Each DC input has an associated LED that
shows the status of the corresponding DC input. If power is presen t on the circuit, the LED is green. If
power is not present, the LED color depends on the alarm configuration. If alarms are configured, the
LED is red when power is not present; otherwise, the LED is off.
If the switch has dual power sources, the switch draws power from the power sour ce with the higher
voltage. If the one of the DC sources fails, the alternate DC source powers the switch, and the
corresponding power status LED is green. The power status for the failed DC source is ei ther off or red,
depending on the alarm configuration.
