II. 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.
III. Connecting the AC-input Power Cord
Step 1: Check that the PGND is securely connected to the earth ground.
Step 2: 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.
Step 3: Check that the PWR LED on the front panel of the router is on for correct connection.
