Description
The power supply is on and operating correctly.
The power supply is in cold standby mode; only the 12 V DC
input is present.
The power supply is uploading firmware.
Warning events are being detected; the power supply continues
to operate. Often these events are because of rising
temperatures. Check the fans and ensure there is proper airflow
through the chassis.
Either the power cord is unplugged or a major error is detected
in the power supply. Examples of a major error are: power
supply failure, an over voltage protection error, an over current
protection error, or a fan failure.
•
If the power cord is unplugged or missing, reattach the
power cord appropriate for your country.
•
If a major error is occurring, Replace the power supply as
soon as possible. To maintain proper airflow through the
chassis, leave the power supply installed in the chassis until
you are ready to replace it.
There is no AC power to any of the power supplies.
