If there is a grounding strip in the Ethernet switch installation environment, attach
one end of the yellow-green protection grounding cable to the grounding screw of

z
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.
