Warning

Statement 1046—Installing or Replacing the Unit

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.

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.

To power up the switch, you must connect the power supplies to one or two power sources. The number of

power sources used depends on the type of power redundancy that you require as follows:
