z If there is no ground bar 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 0.5 m
into the earth. In this case, the yellow-green PGND wire should be welded with the
angle iron (steel pipe) and the joint should be processed against eroding. (For the
S9500 series, the grounding screw is on the rear panel. Connect it as illustrated in
Figure 4-7).

z If both ground bar and the conditions for burying the grounding body are not
available, an AC-powered Ethernet switch can be grounded using 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.
