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 ground wire 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, and the
Ethernet switch is AC powered, you can 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.
