The output shall shutdown when an overcurrent condition is detected.
It will auto restart after 1sec; however if the overcurrent condition is redetected the output will once again
shutdown.
The output will once again re-start, however if the overcurrent condition persists it will latch of after the fifth 60
unsuccessful attempt.
To reset the latch it will be necessary to toggle the PS_ON_L signal (B4) or recycle the incoming DC source.

The output shall shutdown when an overcurrent is detected.
It will auto restart after 2sec; however if the overcurrent is re-detected the output will once again shutdown. 2.2
This cycle will occur indefinitely while the overcurrent condition persists.

DESCRIPTION
Input voltage operating within normal specified range
Input voltage operating in:
1) overvoltage warning, or
2) undervoltage warning range
Input voltage operating:
1) above overvoltage range, or
2) below undervoltage range, or
3) not present
Output
POWER GOOD
Solid Green
Main output and standby output enabled with no power supply warning or fault
detected
Output
STANDBY
Blinking Green
Standby output enabled with no power supply warning or fault detected
Output
WARNING
Blinking Amber
Power supply warning detected as per PMBus STATUS_X reporting bytes
Output
FAULT
Solid Amber
Power supply fault detected as per PMBus STATUS_X reporting bytes
LED fault/warning operation follows PMBus fault/warning reporting status flags and will thus also be 'sticky' (i.e. even if actual fault/warning is cleared, LED will still be in FAULT or WARNING mode until PMBus status flags
are cleared with the CLEAR_FAULTS command
