QFX10002 Chassis Grounding Cable and Lug Specifications

Efficient device operation requires proper site planning and maintenance and proper
layout of the equipment, rack or cabinet (if used), and wiring closet.
To plan and create an acceptable operating environment for your device and prevent
environmentally caused equipment failures:
Keep the area around the chassis free from dust and conductive material, such as
metal flakes.
Follow prescribed airflow guidelines to ensure that the cooling system functions properly
and that exhaust from other equipment does not blow into the intake vents of the
device.
Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent
damaging the equipment. Static discharge can cause components to fail completely
or intermittently over time.
Install the device in a secure area, so that only authorized personnel can access the
device.
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
QFX10002, connect a grounding cable to earth ground and then attach it to the chassis
grounding points.
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.
CAUTION: Before switch installation begins, a licensed electrician must
attach a cable lug to the grounding cables that you supply. See
the QFX10002 to Ground" on page
