The following alarms, LEDs, and other conditions indicate a problem with the AC or DC
power system:
If all AC or DC PSMs have failed, the system temperature might have exceed the
threshold, causing the system to shut down.
The yellow LED blinks when a AC or DC PSM is out of power limit or over
PWR OK
current condition.
The red LED lights when the PSM is not receiving enough airflow to maintain
FAULT
proper temperature.
The red FAULT LED lights when the AC or DC output voltages are not within range.
The yellow LED blinks when the AC or DC voltage is present, but out of limits.
