If there is no grounding strip but earth nearby and the grounding body is allowed to be buried, you
can simply hammer an angle iron or steel pipe no shorter than 0.5m into the earth. In this case, the
yellow-green protection grounding cable should be welded with the angle iron (steel pipe) and the
joint should be processed against eroding.

If there is no grounding strip and no grounding body can be buried, the AC-powered Ethernet
switch can be grounded through the PE wire of the AC power supply. In this case, make sure that
the PE wire of the AC power supply has been well grounded at the power distribution room or AC
power supply transformer side.
