power supply should light. A problem exists if this LED does not light. Verify that the power
supply is properly seated in the connector. If so, also check the external power source and
connection to the power supply. If the power supply, external power source, and power
connection are okay, replace the converter.

in the power supply backplane. Gently push the converter in until it is firmly seated in the
backplane connector.
3. If the power converter is installed and power is applied, the green LED on the front
panel of the converter should light. A problem exists if this LED does not light. Verify
