Installing the Switch Chassis
c) Tighten the 10-32 screws to 20 in-lb (2.26 N·m) or tighten the 12-24 screws to 30 in-lb (3.39 N·m).
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
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.
