Installation Manual
H3C S9500 Series Routing Switches
Note:
Rather than specifying the switch model or showing the actual location of the switch
power input or grounding screw, the following figures are primarily intended for
illustrating the switch grounding, either via grounding screw or power input, in specific
grounding environments.
If a ground bar is available, attach one end of the yellow-green PGND wire of the
switch to a grounding bolt of the ground bar and fasten the captive screws.
Caution:
Note that neither the fire hydrant nor lightning rod of a building is suitable for grounding
the switch. The PGND wire of the switch should be connected to the grounding device
in the equipment room. (For the S9500 series, the grounding screw is on the rear panel.
Connect it as illustrated in Figure 3-5).
