Before installing the chassis in a four-post rack, you must install the rear rack-mount brackets on each side
of the chassis.
Determine where in the rack you want the chassis to be mounted. If you are mounting more than one chassis
in the rack, then start from the bottom up or the center of the rack. The following figure shows the brackets
attached to the chassis
Step 1
Locate the threaded holes on the side of the chassis. Ensure that you hold the rear rack-mount bracket with the ear and
holes facing outward and towards the rear of the chassis.
The following figure shows where to attach the rear rack-mount brackets to the Cisco Catalyst 9800-40 Wireless Controller.

Insert the black screws on one side. Do not fully tighten the screws. The rear bracket holes are slotted to allow for
adjustment. Do not fully tighten the screws until the chassis is installed in the four-post rack.

on the other side of the chassis. Use black screws to secure the rack-mount brackets to the chassis.
Mounting the Controller in the Rack
After installing the rack-mount brackets on the chassis, mount the chassis by securing the rack-mount brackets
to two posts or mounting strips in the rack using the screws provided. Because the rack-mount brackets support
the weight of the entire chassis, ensure that you use all the screws to fasten the two rack-mount brackets to
the rack posts.
