If there is no appropriate grounding point on the cabinet, we also can
connect the grounding cable of the router to other grounding bar of the
installation place.
Fire hose and lightning rod grounding of the building are not the proper
grounding location; the grounding cable of the router should be connected
to the engineering grounding of the equipment room.

Install AC Power SPD
The AC power SPD (surge protection device) suppresses the transient overvoltage caused by
lightning inductance shock or other reasons on the power transmission line. When a SPD is
used, the AC power first enters the SPD and then enters the router.
