Grounding the switch
WARNING!
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 directly connected to the
chassis to form the chassis ground (commonly known as PGND). You must securely connect this
chassis ground to the earth so the faradism and leakage electricity can be safely released to the
earth to minimize EMI susceptibility of the switch.
NOTE:
The power and grounding terminals in this section are for illustration only.
WARNING!
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a
fire main or lightning rod.
To connect the grounding cable:
1.
Attach the two-hole grounding lug at one end of the grounding cable to a grounding point on the
switch chassis (see "
Connecting the grounding cable to the S9804 switch
").
2.
Remove the hex nut of a grounding post on the grounding strip.
