Grounding the Switch
Step 4
If you have attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility
ground.
Grounding the Switch
The switch chassis is automatically grounded when you install the switch properly in a grounded rack with
metal-to-metal connections between the switch and rack.
Alternatively, you can ground the chassis (this is required if the rack is not grounded) by attaching a
customer-supplied grounding cable to the chassis grounding pad and the facility ground. We recommend
using 6-AWG wire.

Step 1
Use a wire-stripping tool to remove approximately 0.75 in. (1.9 cm) of the covering from the end of the grounding wire.
Step 2
Insert the stripped end of the grounding wire into the open end of the grounding lug, and use a crimping tool to crimp
the lug to the wire. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire
out of the crimped lug.
Step 3
Remove the label covering the grounding pad on the chassis. Secure the grounding lug to the chassis grounding pad with
two M4 screws, and tighten each screw to 11.5 to 15 in-lb (1.3 to 1.7 N·m) of torque.
