Problem
Description: The following alarms, LEDs, and other conditions indicate a problem with the AC or DC power
system:
•
If all AC or DC power supply modules (PSMs) have failed, the system temperature might have exceeded
the threshold, causing the system to shut down. See Step 9 for instructions on how to restart a
high-capacity AC or DC PSM after a shut down due to an over-temperature situation.
•
The yellow PWR OK LED blinks when an AC or a DC PSM is out of the power limit or is in an overcurrent
condition.
•
The red FAULT LED lights when the PSM is not receiving enough airflow to maintain the proper
temperature.
•
The red FAULT LED lights when the AC or DC output voltages are not within range.
•
The yellow INP0 LED blinks when the AC or DC voltage is present, but out of limits. This LED blinks
continuously for approximately a few seconds on and a few seconds off.
