3. Keep the upside of the RPS plug on top and plug it in the RPS DC receptacle (see callout 1 in Figure
20 ). (If you plug it with the upside down, the insertion is not smooth because of the specific
structure design of the RPS DC receptacle and the RPS plug.)
4. Use a flat-blade screwdriver to attach the two screws on the RPS plug clockwise to secure the plug
to the RPS DC receptacle (see callout 2 in Figure 20 ).

5. Connect the other end of the +12 VDC RPS power cord to the RPS power source.
6. Verify that the RPS LED on the front panel of the switch is ON. If yes, the power is correctly
connected.
