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, the
Ethernet switch with AC power supply can be grounded through the PE wire of
the AC power supply. In this case, make sure the PE wire of the AC power
supply has been well grounded at the power distribution room or AC
transformer side.
