a Ensure that the power converter (NTMX72) is fully inserted. A major
audible alarm may sound. This alarm is silenced when power to the
NTMX72 circuit card is restored.
Note:

converter to the Reset position. Set the associated circuit breaker on the
FSP to the ON position.
If both the converter FAIL LED and FRAME FAIL lamp on the FSP go

go OFF, hold the switch on the NTMX72AA converter in the Reset
position and simultaneously set the associated circuit breaker on the FSP
to the ON position. Both the converter FAIL LED and FRAME FAIL lamp
on the FSP will go OFF. Go to step 17.
