Figure 158: Cisco ASR 9904 Router Chassis with Air Baffle in 2-Post 23-Inch Rack
An electrical conducting path must exist between the product chassis and the metal surface of the enclosure
or rack in which it is mounted, or to a grounding conductor. The chassis has two grounding points on each
side of the baffle, however only one ground is required. The other will be grounded through the top and bottom
air deflectors.
Figure 159: Cisco ASR 9904 Router Baffle Ground , on page 150
shows the baffle ground
location on the chassis.
You can ground the baffle by either attaching a grounding lug to the chassis (
Bonding and Grounding Guidelines
), or by using thread-forming mounting screws to establish a metal-to-metal
contact. If you are using screws, remove any paint or other non-conductive coatings on the surfaces between
the mounting hardware and the enclosure or rack. Clean all surfaces and apply an antioxidant applied before
the installation.
