Grounding The Chassis - Cisco Nexus 3400 Series Hardware Installation Manual

Grounding the Chassis

1 Three customer-supplied screws (typically M6 x 10
mm screws or the appropriate screws for the rack) to
hold each side of the chassis to the two-post rack.
Step 5
Use the second person to secure the three customer-supplied rack-mount screws (typically M6 x 10 mm or other appropriate
screws for the rack) on each center-mount bracket to attach the chassis to the rack. Tighten each screw to the appropriate
torque setting for the screws (for M6 x 10 mm screws, use 40 in-lbs [4.5 N·m] of torque).
Grounding the Chassis
The switch chassis is automatically grounded when you properly install the switch in a grounded rack with
metal-to-metal connections between the switch and rack.
You can also ground the chassis, which is required if the rack is not grounded, by attaching a customer-supplied
grounding cable. Attach the cable to the chassis grounding pad and the facility ground.
Warning Statement 1024 Ground Conductor
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or
operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is available.
Warning
Statement 1046 Installing or Replacing the Unit
