Statement 1046— Installing or Replacing the Unit
When installing or replacing the unit, the ground connection must always be made first and disconnected last.
Warning
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.
2 M4 screws are used to
secure the grounding lug to

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
You start the switch by connecting it to its dedicated power source. If you need n +1 redundancy, you must
connect each of the power supplies to one or two power sources. If you need n + n redundancy, you must
connect each power supply in a switch to a different power source.
