Installing the -48V Converters
To install a -48V Converter in a chassis, proceed as follows. Refer to the system specification
section in this manual for the -48V Converters. Figure 2-4 shows the location of the fuse on
the converter board.
1. Remove the panel covering the rear power slots. You may insert or remove the module in
either slot NS1 or NS2 while power is on or off. You may insert or remove the panel while
power is on or off.
2. Hold the converter by its metal handle and align the PCB edges with the slot rail guides
in the chassis. Gently push the converter in until it is firmly seated in the backplane
connector.
3. When 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 that
the power converter is properly seated in the connector. If so, also check the external
power source and connection to the power supply. If the power converter is properly
seated, and the external power source and power connections are operational, replace the
converter.
4. Replace the panel cover.
