Connect the QFX5200 to Earth Ground
You must install the QFX5200 in a restricted-access location and ensure that the chassis is always
properly grounded. The QFX5200 has a two-hole protective grounding terminal provided on the chassis.
See Figure 49 on page 110. We recommend that you use this protective grounding terminal as the
preferred method for grounding the chassis regardless of the power supply configuration. However, if
additional grounding methods are available, you can also use those methods. For example, you can use
the grounding wire in the power cord for AC power or use the grounding terminal or lug on a DC power
supply. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-
hole protective grounding terminal.
CAUTION: Ensure that a licensed electrician has attached an appropriate grounding lug
to the grounding cable that you supply. Using a grounding cable with an incorrectly
attached lug can damage the switch (for example by causing a short circuit.)
NOTE: Mount your switch in the rack or cabinet before attaching the grounding lug to the
switch. See "Mounting a QFX5200 in a Rack or Cabinet" on page
Ensure that you have the following parts and tools available:
• Grounding cable for your QFX5200 device—The grounding cable must be 14 AWG (2 mm²),
minimum 90° C wire, or as permitted by the local code (not provided).
• (QFX5200-32C and QFX5200-32C-L) Grounding lug for your grounding cable—The grounding lug
required is a Panduit LCD10-10A-L or equivalent (not provided).
