Two-Post Rack Installation
Before you begin
The Cisco Catalyst 9800-40 Wireless Controller can be installed on a two-post rack, either 19 inch or 23 inch.
We recommend that you allow at least 1 or 2 inches (2.54 or 5.08 cm) of vertical clearance between the
controller and any equipment directly above and below it.
Step 1
On the chassis, ensure that all the screw fasteners on the installed components are securely tightened.
Step 2
Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are engaged or that
the rack is otherwise stabilized
Step 3
(Optional) Install a shelf in the rack to support the Cisco Catalyst 9800-40 Wireless Controller . If you use a shelf, it helps
support the chassis while you secure it to the rack.
If you are using a shelf, place the chassis on the shelf and slightly raise the front of the chassis to align the
mounting bracket holes with the rack post holes while allowing the bottom of the chassis to rest on the shelf.
Note
Step 4
With two people, lift the chassis into position between the rack posts.
Step 5
Align the mounting bracket holes with the rack post holes and attach the chassis to the rack.
Step 6
Position the chassis until the rack-mounting flanges are flush against the mounting rails on the rack.
To allow space to attach the cable-management brackets to the chassis in the rack easily, use the rack-mount
bracket ear holes mentioned in Steps 7 and 8.
Tip
Step 7
Hold the chassis in position against the mounting rails in the equipment rack and follow these steps:
a.
Insert the bottom screw into the second hole up from the bottom of the rack-mount ear and use a hand-held screwdriver
to tighten the screw to the rack rail.
To make installation easier, insert one screw at the bottom of the chassis and the next screw at the top of
the chassis diagonally from the first screw
Tip
b.
Insert the top screw into the second hole from the top of the rack-mount ear diagonally from the bottom screw and
tighten the screw to the rack rail.
c.
Insert the rest of the screws to secure the chassis to the rack equipment.
Step 8
Tighten all the screws on each side to secure the chassis to the equipment rack.
