Installing the Chassis
You can alternatively ground the chassis (this is required if the rack is not grounded) by attaching a
customer-supplied grounding cable to the chassis grounding pad and the facility ground.
Note
The location of the grounding pad on each switch can be found in the
Note
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.
The switch is grounded when you connect the chassis and the power supplies to the earth ground in the
following ways:
• You connect the chassis (at its grounding pad) to the data center ground. If the rack is fully-bonded and
grounded, you can ground the switch by connecting it to the rack.

Before you begin
Before you can ground the chassis, you must have a connection to the earth ground for the data center building.
If you installed the switch chassis into a bonded rack (see the rack manufacturer's instructions for more
