Installing the Chassis
Before you begin
Before you can ground the chassis, you must have a connection to the earth ground for the data center building.
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. We recommend 6-AWG wire for the U.S. installations.
Step 2
Insert the stripped end of the grounding wire into the open end of the grounding lug. Use a crimping tool to crimp the
lug to the wire, see 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 the previous figure. 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 the facility ground.
Starting the Switch
To power up the switch, follow these steps:
Before you begin
• Verify that the switch is fully installed and secured to a rack.
• Verify that the switch is adequately grounded to the facility earth ground or to a grounded rack.
