Installation GuideQX-S6600 Series Ethernet Switches 3 Installing the switch3-10Mounting the switch in the rack (II)Grounding the switchWARNING:Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.The power input end of the switch has a noise filter, whose central ground is directlyconnected to the chassis to form the chassis ground (commonly known as PGND). Youmust securely connect this chassis ground to the earth so the faradism and leakageelectricity can be safely released to the earth to minimize EMI susceptibility of the switch.You can ground a switch by using a grounding strip at the installation site or the AC powercord connected to the switch.
