protection. For information about lightning protection, see
H3C Network Devices Lightning
Protection Guide
.
To protect against the following types of issues, use a grounding cable to connect the switch to the
earthing facility at the installation site:
•
Bodily injury from electric shocks.
•
Device and power and data line damages.
•
Electrical fires, lightning strokes, electromagnetic coupling interferences, and ESD damages.
You can ground the switch in one of the following ways, depending on the grounding conditions
available at the installation site:
•
Grounding the switch with a grounding strip
•
Grounding the switch with a grounding conductor buried in the earth ground
