Step 1: Make sure that the PGND is properly grounded to the earth.
Step 2: Put the power switch of the router to OFF, then insert one end of the DC power cord
accompanying the router into the power socket on the chassis rear panel, and then connect the other
end of the power cord (with a BGND connector and a –48 VDC connector) to a –48 VDC power supply.
When connecting the DC power cord, notice the labels on the power cord to avoid wrong connection.
Step 3: Place the power switch of the router to the ON position.
Step 4: Check the POWER LED on the front panel of the router. ON indicates correct connection.
