3. Secure the grounding lug to the protective earthing terminal with the washers and screws.
4. Dress the grounding cable and ensure that it does not touch or block access to other switch components.
WARNING: Ensure that the cable does not drape where people could trip over it.
Step 4: Connect Power to the Switch
We ship the QFX5120 switches with two power supplies preinstalled. Each power supply is a hot-removable and
hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running: You can install power
supplies in the slots next to the fan modules without powering off the switch or disrupting switch functions.
