For installations that require a separate grounding conductor to the chassis, the switch
must be adequately grounded before power is connected to ensure proper operation
and to meet safety and electromagnetic interference (EMI) requirements. To ground a
QFX10000 modular chassis, connect a grounding cable to earth ground and then attach
it to the chassis grounding point on the rear of the chassis beneath.
WARNING: The switch is pluggable type A equipment installed in a
restricted-access location. It has a separate protective earthing terminal
provided on the chassis in addition to the grounding pin of the power supply
cord. This separate protective earthing terminal must be permanently
connected to earth ground for installations that require a separate grounding
conductor to the chassis.
WARNING: To comply with GR-1089 requirements, all intra-building copper
cabling used for SFP+, QSFP+, and QSFP28 ports must be shielded and
grounded at both ends.
