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+ and QSFP+ 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
Earth Ground to a QFX5100 Device" on page
attached lug can damage the switch.
Before connecting the switch to earth ground, review the following information:
A protective earthing terminal bracket is provided in the accessory kit for connecting
the switch to earth ground. This L-shaped bracket attaches to the side of the QFX5100
chassis through the mounting bracket, providing a protective earthing terminal for the
switch. Screws for attaching the earthing terminal bracket are provided in the accessory
kit.
The grounding lug required is a Panduit LCD10-10A-L or equivalent. This grounding lug
is provided in the accessory kit. The grounding lug provided accommodates 14–10 AWG
(2–5.3 mm²) stranded wire.
The grounding cable that you provide for a QFX5100 device must be 14 AWG (2 mm²),
minimum 60° C wire, or as permitted by the local code.
