AC power socket (recommended)
You are recommended to use a three-terminal single-phase power socket with ground contact, which
must be grounded reliably. Normally, the ground contact of the power supply system in a building was
buried during construction and cabling. Still, before connecting the AC-input power cord, you must make
sure that the power supply of the building is well grounded.
Connecting the AC power cord
Step1 Make sure that the PGND is securely connected to the earth ground.
Step2 Insert one end of the power cord accompanying the router into the power socket on the chassis rear
panel, and fix the cable onto the cable-retention clip with a cable strap. Connect the other end of the
cable to an AC power source at your installation site.
Step3 Place the power switch of the router to the ON position.
Step4 Check that the PWR LED on the front panel of the router is on for correct connection.
Connecting the DC Power Cord
DC power supply
Rated voltage range: –60 VDC to –48 VDC
The following figure illustrates the power socket and switch for a DC-powered router:
