II. Connecting AC power cord
Step 1: Connect one end of the chassis grounding wire (coming
with the switch) to the grounding screw on the rear of the chassis and
the other end to the ground nearby.
Step 2: Connect one end of the power cord to the power socket
on the rear panel of the chassis and the other end to an outside AC
power socket.
Step 3: Check whether the PWR LED on the front panel of the
switch is ON. If the LED is ON, it shows the power cord is properly
connected.
Caution:
Before powering on the switch, you should properly connect the
grounding wire.
