building was buried in the ground during the construction and wiring. Still, you must
make sure of that.

II. Connecting the AC-input power cord
Step 1: Connect one end of the chassis ground wire to the grounding screw on the rear
of the chassis and the other end to the ground as near as possible.
Step 2: Connect one end of the power cord to the power socket on the rear of the
chassis, and plug the other end to the AC power jack of the power source.
Step 3: Check that the PWR LED on the front panel of the switch is ON.
Caution:
Before powering on the switch, connect the ground wire.

3.2.2 Connecting the Ground Wire

Caution:
Correctly connecting the switch ground wire is crucial to the lightning protection and
electromagnetic susceptibility (EMS) of a switch.
The power input end of the switch is connected with a noise filter, whose central ground
is directly connected to the chassis, forming the chassis ground (commonly known as
PGND). This chassis ground must be securely connected to the earth ground so that
the faradism and leakage electricity can be safely released to the ground, enhancing
the EMS capability of the switch.
