Alternate Method to Ground QFX5200-32C-DC Systems
Ensure that you have the following parts and tools available to ground the chassis using this method:
• M5 pan-head screw x .08 mm with integrated washer (not provided)
• M5 lug (not provided)
• 12 AWG (2.5 mm²) standard wire, 90° C wire or heavier (not provided)
• Number 2 screwdriver (not provided)
To connect earth ground to a QFX5200-32C-DC power supply:
1. Have a licensed electrician aached the M5 grounding lug to the grounding cable that you supply.
CAUTION: Using a grounding cable with an incorrectly aached lug can damage the
switch.
2. Ensure that all grounding surfaces are clean and brought to a bright nish before grounding
connecons are made.
3. Connect one end of the grounding cable to a proper earth ground, such as the rack in which the
switch is mounted.
4. Place the grounding lug that is aached to the grounding cable over the protecve earthing terminal
on the DC power supply.
5. Use a screwdriver to secure the grounding lug to the protecve earthing terminal with a M5 pan-
head screw with integrated washer.
6. Dress the grounding cable and ensure that it does not touch or block access to other device
components and that it does not drape where people could trip over it.
We recommend that you connect earth ground to a QFX5110 DC chassis using the "Connect the
QFX5200 to Earth Ground" on page 109 method. However if you can’t access the chassis using the
