Installing a Chassis
What to do next
After you have secured the chassis to the rack, you can connect the chassis to the data center ground.
Grounding the Chassis
The switch chassis is automatically grounded when you properly install the switch in a grounded rack with
metal-to-metal connections between the switch and rack.
Note
You can also ground the chassis, which is required if the rack is not grounded, by attaching a customer-supplied
grounding cable. Attach the cable to the chassis grounding pad and the facility ground.
Warning
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.
An electrical conducting path shall exist between the product chassis and the metal surface of the
enclosure or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be
provided by using thread-forming type mounting screws that remove any paint or non-conductive
coatings and establish a metal-to-metal contact. Any paint or other non-conductive coatings shall be
removed on the surfaces between the mounting hardware and the enclosure or rack. The surfaces shall
be cleaned and an antioxidant applied before installation.
Statement 1024 Ground Conductor
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor
or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate
electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.
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.
