160-A power supply or the three-input 240-A power supply is not receiving enough
airflow to maintain proper temperature.
During normal operation:
If the green CB ON and the blue
faceplate are on, the power source is good and the power supplies are functional.
The LED on the faceplate of each two-input 160-A power supply faceplate or

input is receiving source DC power.
To verify that a power supply is functioning normally:
Check the LEDs on each two-input 160-A power supply faceplate.
