*If Interrupt function is not used, this PM104 line can be used for general purpose Input/Output.
2.9 Low Input Alarm
This output signals the Power Management circuit (PM104) or external circuitry that main input power has failed. The Low Input Alarm signal has a 100K current limiting resistor in a series.
If the PM104 is not installed, then external circuitry can access the Low Input Alarm output on connector
