Connecting Earth Ground To A Qfx10000 - Juniper QFX10016 Hardware Manual

Connecting Earth Ground to a QFX10000

162
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect the chassis to earth ground before you connect it to
power.
For installations that require a separate grounding conductor to the chassis, you must
attach a protective earthing terminal bracket on the chassis. There are mounting holes
for the terminal bracket on the left-rear side of the chassis to connect to the earth ground
(see Figure 68 on page 164).
Before you connect earth ground to the protective earthing terminal of a QFX10008 or
QFX10016, ensure that a licensed electrician has attached an appropriate grounding lug
to the grounding cable.
CAUTION: Using a grounding cable with an incorrectly attached lug can
damage the switch.
NOTE: Mount your switch in the rack before attaching the grounding lug to
the switch. For the QFX10008, see:

Ensure that you have the following parts and tools available:
An electrostatic discharge (ESD) grounding strap (provided).
Protective earthing terminal lug (provided).
Grounding cable for your QFX10000 (not provided)—The grounding cable must be
6 AWG (13.3 mm²), minimum 90° C wire, or as permitted by the local code.
Grounding lug for your grounding cable (provided)—This bracket attaches to the lower
left corner of the QFX10000 switch chassis next to PSU 5, providing a protective
earthing terminal for the switch. The grounding lug required is a Panduit LCD6-10A-L
or equivalent.
A Phillips screwdriver to tighten the two screws that are mounted on the chassis.
An AC-powered QFX10000 gains additional grounding when you plug the power supply
in the switch into a grounded AC power outlet by using an AC power cord appropriate
for your geographical location. See AC Power Cord Specifications for a QFX Series Device.
