Attaching a Chassis Ground Connection
Before you begin
This equipment must be grounded. 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 1024
Warning
Before you connect the power or turn on the power to the chassis, you must provide an adequate chassis
ground (earth) connection for the chassis. A chassis ground connector is available on each Cisco CBR-8
chassis.
The grounding wire is always the first to be installed or connected and the last to be removed or disconnected.
Caution
