The fans are not receiving power

•
If the LED is off, check the
power LED on the other
modules to make sure they
are receiving power.
If using a DC power source,
check your power source for
problems.
If using AC power supplies,
take the actions described in
the Meaning or Action

supply LED. If these actions
do not resolve the problem,
check the LED on each power
supply or enter the show
chassis command at any CLI
prompt to determine if a
power supply has failed. If a
power supply has failed, you
need to replace it. For more
information, refer to
