Connecting the grounding cable to the chassis
CAUTION:
The primary grounding point and auxiliary grounding point are located on the left panel of the

point before you mount the switch in the rack.

two-hole grounding lug to the grounding point on the switch. If the grounding cable length or
grounding lug type cannot meet your requirement, make an applicable grounding cable or contact
H3C Support.
The grounding screws provided with the switch are applicable to both the primary and auxiliary
