Before you connect power or turn on power to your chassis, you must provide an adequate chassis ground
(earth) connection for the chassis. A chassis ground connector is provided on each Cisco Catalyst CW9800M
Wireless Controller. There is a stud on the rear left side of the chassis.
When installing or replacing the unit, the ground connection must always be made first and disconnected
last
