I
The DS1200-3 power supply contains enhanced monitoring and control functions implemented via the I
DS1200-3 I
communication bus is powered either by the internal 3.3V supply or from an external power source connected to the
StandBy Output (ie: accessing an unpowered power supply as long as the StandBy Output of another power supply
connected in parallel is on).
If units are connected in parallel or in redundant mode, the StandBy Outputs must be connected together in the system.
Otherwise, the I

S_INT (Alarm) – (pin D3)
S_INT is used to send a signal to the system that a fault in the power supply occurred. This signal is normally logic level
HIGH. It will go to a LOW logic level when a fault bit has been set in the power supply’s status register. To reset the
S_INT signal back to normal (logic HIGH level), perform one of the following actions - (1) recycle input AC power, (2)
toggle PSON signal and (3) issuance of a CLEAR_FAULTS PMBus

The noise on the address lines A0 and A1 will be less than 100mV peak-to-peak. This noise measurement should be
made at the power supply output connector.
