TIP: Because the rear support anchors are attached to the chassis
grounding points, it is best to connect the chassis to earth ground while
performing this step. See
“Connecting Earth Ground to a QFX3008-I
Interconnect Device” on page 174 for more information.

Supported Platforms
QFX3000-G
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, we recommend that the QFX3008-I Interconnect device be adequately
grounded before it is connected to power.
Two pairs of threaded inserts (PEM nuts) are provided on the QFX3008-I Interconnect
device for connecting the device to earth ground. The first pair is sized for M6 screws and
is located below the wiring tray on the bottom left corner at the rear of the chassis. The
second pair is sized for UNC ¼-20 screws and is located below the second wiring tray on
the bottom right corner at the rear of the chassis. The grounding points are spaced 0.625
in. (15.86 mm) apart. The grounding lug required is a Panduit LCD2-14A-Q or equivalent.
