Grounding Cable and Lug Specifications for a QFX5100 Switch
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
QFX5100 switch, connect a grounding cable to earth ground and then attach it to the
chassis grounding points.
