Grounding the Fabric Interconnect
Warning
Statement 1046 Installing or Replacing the Unit
To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be
made first and disconnected last.
Before you begin
Before you can ground the chassis, you must have a connection to the earth ground for the data center building.
Procedure
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.
