Step 1: Make sure that the PGND is properly grounded to the earth.
Step 2: Insert one end of the DC power cord accompanying the router into the power socket on the
chassis rear panel. 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: Check the POWER LED on the front panel of the router. ON indicates correct connection.
