Grounding the Chassis
its grounding pad to the rack. Otherwise, you must connect the chassis grounding pad directly to the data
center ground.
Step 1 Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) 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 (see Callout 2 in the following figure). 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
Secure the grounding lug to the chassis grounding pad with two M4 screws (see Callouts 1 and 3 in the previous figure),
and tighten the screws to 11 to 15 in-lb (1.24 to 1.69 N·m) of torque.
Step 4 Prepare the other end of the grounding wire and connect it to an appropriate grounding point in your site to ensure an
adequate earth ground for the switch. If the rack is fully bonded and grounded, connect the grounding wire as explained
in the documentation provided by the vendor for the rack.
