Grounding the switch by using a grounding strip

CAUTION:
• Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. For
information about lightning protection for the switch, see H3C Lightning Protection Guide.
• Do not connect the grounding cable to a fire main or lightning rod.
• To guarantee the grounding effect and avoid switch damage, use the grounding cable provided
with the switch to connect the switch to a grounding strip in the equipment room.
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.
To ground the switch by using a grounding strip:
Attach the two-hole grounding lug at one end of the grounding cable to a grounding point on the
1.
switch chassis. For more information, see
Remove the hex nut of a grounding post on the grounding strip.
2.
Attach the ring terminal at the other end of the grounding cable to the grounding post on the
3.
grounding strip, and secure the ring terminal to the grounding post with the hex nut.
