Solution
Check that the power
supply fans are running and
that the air filters are clean
to be sure they are
functioning and providing
sufficient airflow through
the power supply.
If there is not sufficient
airflow, replace the air
filters.
Use the
show chassis
command
environment pem
to view the temperature.
Check the input feed
connectivity and voltage
levels. Voltage range should
be between –40 V and
–72 V.
Replace the power supply.
Install a supported power
supply.
Install a supported power
supply in the appropriate
slot.

set
chassis pem feeds
command. Correct one or
both of the following:
add or remove cables
connected to the power
supply
reconfigure the number
of feeds and the input
current by using the set
