Generally, the cabinet has a grounding strip. The grounding cable of the switch can
be connected to the grounding strip of the cabinet.
II. Other grounding environment
Note:
The following figures are sketch maps, and just show the way of cable connecting
rather than the real layouts.
Hereafter introduced some methods for grounding the switch in different environment.

If there is a grounding strip in the Ethernet switch installation environment, attach

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.
